EJBCA - The J2EE Certificate Authority - Welcome

EJBCA - The J2EE Certificate Authority - Welcome: "EJBCA is a fully functional Certificate Authority. Based on J2EE technology it constitutes a robust, high performance and component based CA. Both flexible and platform independent, EJBCA can be used standalone or integrated in any J2EE application.

EJBCA is an enterprise class PKI, meaning that you can use EJBCA to build a complete PKI infrastructure for your organisation. If you only want to issue a few single certificates for testing, there are probably options that will get you started quicker, but if you want a serious PKI we recommend EJBCA.

You can use EJBCA to issue certificates for different purposes such as:

* Strong authentication for users accessing your intranet/extranet/internet resources.
* Secure communication with SSL servers and SSL clients.
* Smart card based login to Windows and/or Linux.
* Signing and enrypting email.
* VPN connections by issuing certificates to your VPN routers such as OpenVPN, Cisco, Juniper etc.
* Client VPN access with certificates in users VPN clients.
* Single sign-on by using a single certificate to secure logon to web applications.
* Creating signed documents.
* Issue citizen certificates for access to government resourses, used in passports etc.
* ... and many many more ..."

The most part of the site development and maintenance processes is the content (mainly texts) modifications in accordance with changeable customer requirements. There is CMS necessity which can allow shifting this routine work from technical to content specialists (advertising manager, linguist, translator etc.) who usually has not HTML knowledge or even to the customer representative who possesses most up-to-date and precise information in application domain."

DataVision Home

DataVision Home: "DataVision is an Open Source reporting tool similar to Crystal Reports. Reports can be designed using a drag-and-drop GUI. They may be run, viewed, and printed from the application or exported as HTML, XML, PDF, LaTeX2e, DocBook, or tab- or comma-delimited text files. The output files produced by LaTeX2e and DocBook can in turn be used to produce PDF, text, HTML, PostScript, and more.

DataVision is written in Java and runs almost anywhere. It can generate reports from databases or text data files. Any database with an available JDBC driver should work: Oracle, PostgreSQL, MySQL, Informix, hsqldb, Microsoft Access, Progress, and more. Columns read from text files can be separated by any character.

Report descriptions are stored as XML files. This means you can not only use the DataVision GUI but you may also edit reports using your favorite text editor."

Google Answers: Protect/encrypt java class (jar) files from theft

Google Answers: Protect/encrypt java class (jar) files from theft: "Obfuscator can not help protect your Java code from decompilers. Obfuscator can hide valuable names but not hide your logic or algorithms. There are a number of Java de-compiler products on the market that do this task such as Mocha, DJ Java Decompiler, Jad, WingDis, DejaVu, open source decompiler Jreverse Pro, Cavaj Java Decompiler, JCavaj Java Decompiler, Decafe Pro, SourceAgain ... etc. They produce readable source code even though your classes have been obfuscated. http://www.excelsior-usa.com/jetprotection.html Excelsior JET JVM offers a solution but actually it recompile your java source code and that is not Java program anymore. The only solution is to create a java secure class loader which does encrypting/ decrypting classes in the memory. We got the solution and is preparing patent it. The secure class loader already apply to SETECS products written in JAVA. It is proven as secure and efficient solution so far."

JavaNCSS - A Source Measurement Suite for Java

JavaNCSS - A Source Measurement Suite for Java: "Ever wondered how many lines of code or how many classes there are in the Sun JDK? Curious about the size of your own projects - or do you want to keep track of your work-progress. That's what JavaNCSS is for.

JavaNCSS is a simple command line utility which measures two standard source code metrics for the Java programming language. The metrics are collected globally, for each class and/or for each function.

Here is an example about what JavaNCSS prints out for the Sun JDK 1.1.5 java.* source tree (update: JDK 1.5 api source tree consists of 569'830 ncss).

JavaNCSS can optionally present its output with a little graphical user interface. To interactively select Java source files for counting, Jacob (a Java class browser and project manager) can be used for this purpose.

JavaNCSS can also be used out of an Ant build.xml script as it comes bundled with an Ant task written by Steve Jernigan. The JavaNCSS Ant Task is documented on a separate page.

You can always find the newest version of this page at: http://www.kclee.de/clemens/java/javancss/"

Terracotta - Enterprise-class clustering for Java

Terracotta - Enterprise-class clustering for Java: "Clustering the JVM, Not the Application
Terracotta DSO is a runtime solution for clustering JVMs, instead of the application. By extending the Java heap, Terracotta DSO creates one “clustered” JVM that shares object state and behavior. Tuning the clustering behavior can now be done at runtime without code changes. Developers can focus on business logic, not infrastructure."

Marthon User Guide

Marthon User Guide: "Marathon is a general purpose tool for both running and authoring acceptance tests geared at the applications developed using Java and Swing. Included with marathon is a rich suite of components to help you interact with your application at the User Interface Level (GUI).

Marathon tests are scripted using Jython, a 100% pure java implementation of the programming language Python -- the emphasis being on a extremely simple, highly readable syntax that customers, analysts, testers and developers can all be comfortable with. But don't let the simplicity fool you. Python is a mature, full-featured programming language, so testers and developers don't need to sacrafice anything in terms of the power and creativity with which they can express their tests.

To aid with the regression testing of existing applications, Marathon comes bundled with a recorder to capture events as you use and interact with your application. These events are then converted into a valid Marathon test which can subsequently be played back."

Topic: JavaLanguage
Vijendra Singh, Mar 14, 2006
Hi, If someone has good command over writing .jj or.jjt files. I need some help in writing code. I need to incorporate in my sqlParser.jj and ultimately sqlParser.java files; so that they can read and parse :- "create view as select * from tablename" statement. This sqlParser.jj files are generating ASCII_char_stream instead Simple_char_stream, but i don't think it will create any problem. So just like it parsers create table...statement,delete,alster tables etc. It sholud also parse view without giving any error. I am giving this file with some modification i tried to do for views but grammar is mistaken please give me some useful way to solve this Thanks Vijendra

Jxp - Introduction

Jxp - Introduction: "Jxp (Java scripted page) is a script-processor/template-engine that can execute template files containing text java code. It contains a parser to parse the script file into an abstract syntax tree and a tree processor (JxpProcessor) that will process the syntax tree to execute the code using reflection API to produce output. Some of the main features of Jxp include:

* Java as template language. Why learn another one? ;)
* support common java language 1.4 constructs (partial 1.5 syntax support on jdk 1.4)
* practical template sources management framework
* support caching of parsed syntax tree to eliminate reparse of template
* a servlet implementation to enable web-scripting
* extensible processing context for defining built-in function on the scripts

Below is an example of a script file"

iScreen - The Java Object Validation Framework

iScreen - The Java Object Validation Framework

iScreen is a Java Object Validation Framework, suitable for validating Java Objects (including JavaBeans) to ensure that they are "valid" according to some definition (usually via configuration). The term 'iScreen' means "information screen," where 'screen' means to protect or conceal. Information, represented by Java objects, are passed through the screen. If they are considered acceptable (i.e. valid), then nothing occurs. If not, then an exception is thrown, allowing the application to notify someone or something of the invalid information.

JAAS Tutorial: Single Sign-On mit Kerberos gegen Windows Domain

JAAS Tutorial: Single Sign-On mit Kerberos gegen Windows Domain

Ein Verzeichnisdienst ermöglicht die zentrale Verwaltung von Ressourcen und ein Single Sign-On über verschiedene Systeme. Die dafür notwendigen Schnittstellen bietet der Java Authentication and Authorization Service (JAAS) und der Java Naming and Directory Service (JNDI).

Dieses Tutorial beschreibt, wie ein Single Sign-On mit JAAS und dem Kerberos Version 5 Authentifizierungsprotokoll umgesetzt werden kann. Als Verzeichnisdienst wurde der Active Directory Service (ADS) von Microsoft verwendet. Mit dem Beispiel wurde das folgende Szenario abgebildet:

* Ein User authentifiziert sich über das Kerberos Version 5 Authentifizierungsprotokoll bei einer Applikation.
* Anschließend wird mittels LDAP aus dem Active Directory des Domänencontrollers die Benutzerrollen des Users ausgelesen.
* Als Beispiel für eine Autorisierung wird, abhängig von den Rollen des Users, die Umgebungsvariablen java.home und user.home ausgegeben.

Tobago

Tobago: "The goal of Tobago is to provide the community with a well designed set of user interface components based on JSF and run on MyFaces.

Tobago is more than just a tag library. The following statements characterize Tobago and make it different from other frameworks:

* The focus of Tobago is to create business applications without the need for HTML design. The development of Tobago pages follows more the development of conventional user interfaces than the creation of web pages.
* The UI components are abstracted from HTML and any layout information that does not belong to the general page structure. The final output format is determined by the client/user-agent.
* A theming mechanism makes it easy to change the look and feel and to provide special implementations for certain browsers. A fallback solution ensures that as much code is reused for new themes as possible.
* A layout manager is used to arrange the components automatically. This means, no manual layouting with HTML tables or other constructs is needed.

The development of Tobago started in 2002."

Multithreaded Job Queue - The Code Project - Threads, Processes & IPC

Multithreaded Job Queue - The Code Project - Threads, Processes & IPC: "In many of our applications we just want to get some thing done asynchronously. This is where some times we prefer to use job queue. Where we can just assign or add a job to the job queue and then it is the job queue's responsibilities to complete the job. This gives the flexibility to the main thread to concentrate on some thing else where the jobs can be processed at the background. If the job queue can be multithreaded and can process multiple jobs at the same time, it is better.

This article describes such an implementation of job queue. This implementation has the following features :

* The job queue is multi threaded, so many jobs can be processed simultaneously. The job queue uses a pool of threads to execute the jobs.
* The job queue supports priorities. The jobs with high priority will be added before the jobs with lower priority, in the queue. So they will be processed before other lower priority jobs.
* The job queue can be paused, so that no new job can be processed from the time of pause. But the user still can add jobs to the queue. The jobs will be processed once the user choose to resume the job queue.
* The number of threads that will be used by the job queue to process the jobs can be increased or decreased at run time.

spawn JVM via RMI

Creating an Activatable Remote Object: "The RMI daemon, rmid, provides a Java virtual machine* (JVM) from which other JVM instances may be spawned."

This technique can be used to implement fail-over scenarios. Using the rmid to spawn a JVM you have to keep in mind that, if you are using just ONE rmid, this would be single point of failure (SPOF)!

Another possibility to start a NEW JVM is to use the classes provided in the ANT framework. If you have a look to the source code of the Ant Task and trace back to the point where a new JVM is startet you will find the class Execute, with which it is possible to start a completly new JVM (FORK).

EMMA: a free Java code coverage tool

EMMA: a free Java code coverage tool: "EMMA: a free Java code coverage tool

Code coverage for free: a basic freedom?



Until recently, the world of Java development had been plagued by an absurd discrepancy: Java developers had excellent free IDEs, free compilers, free test frameworks but had to rely on code coverage tools that charged an arm and a leg in license fees. As a Java pro, I would like to use the same free coverage tool regardless of whether it is a massive commercial project at work or a small fun project at home. I've created EMMA to be that tool.

EMMA is an open-source toolkit for measuring and reporting Java code coverage. EMMA distinguishes itself from other tools by going after a unique feature combination: support for large-scale enterprise software development while keeping individual developer's work fast and iterative. Every developer on your team can now get code coverage for free and they can get it fast!

Chances are, you've come here already knowing what coverage is all about and are, in fact, wondering what EMMA offers and why it is worth checking out. Explore the rest of this site to see why."

OSWorkflow - OSWorkflow Overview

OSWorkflow - OSWorkflow Overview: "OSWorkflow is fairly different from most other workflow systems available, both commercially and in the open source world. What makes OSWorkflow different is that it is extremely flexible. This can be hard to grasp at first, however. For example, OSWorkflow does not mandate a graphical tool for developing workflows, and the recommended approach is to write the xml workflow descriptors 'by hand'. It is up to the application developer to provide this sort of integration, as well as any integration with existing code and databases. These may seem like problems to someone who is looking for a quick 'plug-and-play' workflow solution, but we've found that such a solution never provides enough flexibility to properly fulfill all requirements in a full-blown application."

Active JMS

Active JMS: "Activating Java Message Services!

The Java Message Service 1.0.2 API has become the standard for MOM products large and small and its implementation ranges from expensive commercial products to freeware and even open source projects. As its name suggests, however, it only provides a standard Java API. This means that:

* There are no widely accepted standardized, non-Java, non-proprietary messaging APIs.
* Support for non-Java access to many JMS systems is very limited.

These two facts often present a problem for an organization, as they often need to have non-Java clients participate in a JMS network. Until now these organizations had few choices—they could use the JMS vendor’s proprietary ActiveX client (if the vendor offered one), or they could use a general purpose 3rd party Java-ActiveX integration tool. Neither of these solutions is ideal, however, because they are contrary to the ‘open’ nature of the JMS specification itself. You get tied down to a particular vender once again!

The Active JMS open source project was created to solve this problem by offering a freely available, non-proprietary, open source ActiveX JMS client API. With it, you can access a large majority of the JMS functionality without compromise."

JMX4Ant

JMX4Ant


Welcome to the JMX4Ant. JMX4Ant is a set of optional Ant tasks that allows interactions with JMX MBeans.

Like many other programmers, I find Ant to be an extremely handy tool to use in automating away the daily drudgery of routine development tasks. In J2EE development, one kind of drudgery that I have a special dislike for is the creation and management of J2EE resources that my applications depend upon.

My motivation therefore was to provide tasks for J2EE resource creation and management from Ant that I use to build/deploy application. (e.g. create my JDBC pool and JMS queues/topics before I deploy my entity and message driven beans...), but the tasks are general enough for much broader use (i.e. general purpose J2EE server and application administration).

If you have questions, comments, or suggestions for improvements please feel free to contact me directly, or post to one of the JMX4Ant lists on Sourceforge.

Version 1.2 of JMX4Ant contains a number of important new features and some bug fixes as well. One of the most requested enhancements for JMX4Ant that is now part of v1.2 is support for WebLogic's Targets property, and addTarget method. This enhancement allows JMX4Ant to deploy and undeploy the resources that are created to a particular target server. For more information on v1.2 features, refer to the Change History section of this document.

The JTR Java Test Runner Project

The JTR Java Test Runner Project: "JTR, acronym for Java Test Runner, is a Java framework that helps developers in building stress test suites. JTR has been devised with some targets in mind:

*

ease of use
*

extendability
*

high configurability
*

modularity
*

rapid development
*

providing J2EE developers with those facilities they usually need
*

ready to use logging facilities
*

Inversion of Control: let the JTR framework inject runtime properties into your runners
*

complete control of the exceptions potentially raised during your test runs

I decided to start devising & coding JTR since I was looking for a framework that could have helped me in building a complex J2EE test environment. The need came out one day at work: I had to stress test a J2EE application and after looking around for suitable testing frameworks I simply decided to start out writing my own one. This approach does not means the JTR framework either is or will be closed with respect to other testing frameworks. Infact it is my firm willing to integrate it with the most popular ones out there nowadays in the next future.
More information covering the most interesting details of the aims sketched above is provided in the reminder of this document (Project Details)."

XStream - About XStream

XStream - About XStream: "XStream is a simple library to serialize objects to XML and back again.
Features

* Ease of use. A high level facade is supplied that simplifies common use cases.
* No mappings required. Most objects can be serialized without need for specifying mappings.
* Performance. Speed and low memory footprint are a crucial part of the design, making it suitable for large object graphs or systems with high message throughput.
* Clean XML. No information is duplicated that can be obtained via reflection. This results in XML that is easier to read for humans and more compact than native Java serialization.
* Requires no modifications to objects. Serializes internal fields, including private and final. Supports non-public and inner classes. Classes are not required to have default constructor.
* Full object graph support. Duplicate references encountered in the object-model will be maintained. Supports circular references.
* Integrates with other XML APIs. By implementing an interface, XStream can serialize directly to/from any tree structure (not just XML).
* Customizable conversion stategies. Strategies can be registered allowing customization of how particular types are represented as XML.
* Error messages. When an exception occurs due to malformed XML, detailed diagnostics are provided to help isolate and fix the problem."

ClassEncrypt Software

ClassEncrypt Software: "ClassEncrypt is a program that can encrypt a developer's class files to prevent malicious users from stealing the source code. The program uses a modular design to allow the developer to create different encryption modules for the program to use. This software does not prevent the developer's software from being pirated.

The software comes with a default module that encrypts and decrypts using the Blowfish algorithm that was created by Bruce Schneier. This software is meant to be a barrier of protection for Java developers who want to market their software. It is not at all foolproof since the software enables the encrypted class files to still run using the regular JVM. It does, however, slow down any reverse engineering that someone may try on the developer's software."

jcoverage

jcoverage

At jcoverage we are about productivity. Our suite of tools and technologies aim to reduce the 'code - test - diagnose - fix' cycle.

If you are using code coverage tools, you are also writing tests. We believe that you can improve your test development productivity at the same time.

Once you have coded, your tests and coverage analysis should run quickly so you can check outcomes and deliver changes as required from test feedback. It should also be able to easily test units in isolation rather than testing system as a whole.

You can start by downloading jcoverage/gpl, our free code coverage tool. Get started and see how much of your code is being covered by tests.

Once you have seen what our free coverage tool can do for you, why not use the fully supported jcoverage commercial edition.

Where your testing is less than adequate, you can improve your test quality and coverage through the use of our mock object technologies, included in our flagship product jcoverage+.

jcoverage+ includes our standard jcoverage technologies and introduces more rigour and finer granularity to your testing, allowing you to simulate and test for scenarios that otherwise would be impossible to test automatically.

Enterprise Java Community: The Power of JAAS: Security System Alternatives

Enterprise Java Community: The Power of JAAS: Security System Alternatives

Purpose

I attended the CIO Forum a several months ago and sat in on a presentation on Identity Management, which is considered by C-level executives one of the hot technologies. From a C-level executive’s perspective, this presentation falls generally under the domain of Identity Management. At the Forum, the speaker briefly discussed RBAC (Role Base Access Control) and anecdotally mentioned that it is a “hard nut to crack.”

This article is an extension of a recent article I published on TheServerSide.com, Exploring J2EE Security for Applications using LDAP. That article identified key interfaces within a J2EE compliant application server that need to be configured in order to build secure applications focusing on RBAC, which is an integral part of Identity Management.

However, the article did not discuss, in detail, alternatives to using LDAP directly for Java Authentication and Authorization Service (JAAS) security, such as a Trust Association, one of the more popular system alternatives. Essentially, the power of JAAS is in its ability to use almost any underlying security system. One of those approaches is to use a Trust Association Interceptor (TAI) instead of direct LDAP access.

aisland: Home

aisland: Home: "AIsland's goal is to provide a framework to build and distribute agents.

The framework exposes objects (graphic module, audio module, neural network, fuzzy logic ...)
to an agent developer, who can glue these modules together using a scripting language, initally JavaScript.

Mobile Agents travel between different AIslands. If an Agent requests a module unknown to an AIsland,
the platform will ask the user for permission to load code from another peer. AIslands can persist trust relationships.

The inital version builds on Java and fat clients, facilitating a Java Swing GUI and a BSF/ Rhino engine,
to script against modules sitting on an JMX component bus hosted by an Avalon based micro kernel.

A port to small devices (J2ME - Java phones) is a future option.

An Agent is represented by an XML document and is distributed as a JXTA Codat.
Agents contain script code, which is interpreted by an AIsland (a JXTA peer) in a secure manner.
Host file systems are protected against malicious agents.

Agents and AIslands communicate using JXTA.
Network access through proxies for HTTP (SOAP) and SMTP is supported as well."

The Ajanta project is aimed at building an infrastructure for mobile agent execution that incorporates security and robustness features as an integral part of the design. The system is being implemented using Java."

An introduction to agents

An introduction to agents: "Summary
Agents draw on and integrate many diverse disciplines of computer science, and although agent technology has not yet hit prime time, it is gathering its share of investment money. Find out what all the uproar is about in this month's column, which examines agents -- what they are and what problems they solve. Columnist Todd Sundsted also shows you how to lay the foundation for a simple agent architecture in Java, which you'll develop in upcoming installments of How-To Java. (2,200 words)"

MindTunnel - A java implementation of an SSHD

MindTunnel - A java implementation of an SSHD: "MindTunnel v0.96

MindTunnel, release 0.96 - Dec 06, 1998

MindTunnel is an entirely FREE(*) SSH (currently v1.5) server program
written in pure Java. It was implemented for fun (or for completeness
of the mindbright ssh-package :-) and is not intended to be a
replacement for 'the real thing'. However, it can be used as a minimal
sshd, supporting only tunneling (i.e. port-forwarding). It has
RSA-authentication as the only means of authentication, the
'authorized_keys' file has changed to be handled in a central place

for all users (hence you don't need to give the users shell-accounts
on the server-machine).

(*) Only restriction is that you can't derive commercial work from it
without our written permission."

A Java API to read, write and modify Excel spreadsheets

A Java API to read, write and modify Excel spreadsheets: "Java Excel API - A Java API to read, write and modify Excel spreadsheets

This is the home page of Java Excel API - open source Java API which allows Java developers to read Excel spreadsheets and to generate Excel spreadsheets dynamically. In addition, it contains a mechanism which allows java applications to read in a spreadsheet, modify some cells and write out the new spreadsheet.

This API allows non Windows operating systems to run pure Java applications which can both process and deliver Excel spreadsheets. Because it is Java, this API may be invoked from within a servlet, thus giving access to Excel functionality over internet and intranet web applications.

Features

# Reads data from Excel 95, 97, 2000 workbooks
# Reads and writes formulas (Excel 97 and later only)
# Generates spreadsheets in Excel 2000 format
# Supports font, number and date formatting
# Supports shading and colouring of cells
# Modifies existing worksheets
# Supports image creation
# Preserves macros on copy
# Customizable logging"

Phex - What is Phex? / Features

Phex - What is Phex? / Features: "Phex is a file sharing program running on the Gnutella Network. It will run on Windows, Mac OS X, Linux, Solaris, and other operating systems supporting Java 1.4.

* Phex is a FREE of spyware and adware
Phex never containd any kind of spyware, adware or any other kind of bundled software. (Softpedia award)

* Multi-plattform support
Whether you use Windows, MAC OS X, Linux (a gentoo-ebuild is avaible via portage) or Solaris Phex is able to run on them all. All you need is a operation system that offers a Java 1.4 Runtime Environment.

* Multi-source downloads (Swarming)
Often the file you like to download is available on several different hosts. Phex will request different segments of the file from each host in parallel. After successfully downloading a segment Phex will merge it with the other segments of that file. This results in a much higher download speed. If a host is too slow the segment is split during download and given to another host. To make sure you never run out of hosts Phex is able to find new download hosts by itself with the automatic search functionality and features the Download Mesh.
You can choose for each download whether the segments should be chosen according to their availability (rarest first, BitTorrent-Style), their place in the file (earlier segments first, useful for previewing the file) or randomly.

* Advanced configuration options
Phex offers very advanced configuration options. Much more than many other clients can offer. Especially advanced user can configure Phex according to their needs and are able to tune and see the effect of different settings.

* Passive searching and snooping for files
With the passive search functionality Phex is able to constantly monitor the traffic that goes through the network and collect search results that match your passive search term. Also Phex snoops the traffic for new download candidates you need to finish your downloads faster. This type of searching is also useful for longtime monitoring of available files on the network.

* Other features include:
o Multiple searches.
o Ultrapeer and compression technology for reduced bandwidth.
o Integrated chat.
o Browse host support.
o Bitzi metadata lookup.
o MAGMA support.
