Drools - Home
Drools - Home
Drools is an augmented implementation of Forgy's Rete algorithm tailored for the Java language. Adapting Rete to an object-oriented interface allows for more natural expression of business rules with regards to business objects.
More importantly, Drools provides for Declarative Programming and is flexible enough to match the semantics of your problem domain. The various parts that compose a rule may be extended to lend domain-specific sense to the rule.

CementJ
CementJ
CementJ alpha will be released soon…………...
CementJ is a Java™ API that provides functionality needed by most Java™/J2EE™ applications that isn't yet provided by the JDK specification directly. In other words, this API is a foundation that fills the gaps between the JDK and applications you code. Functionality includes:
*
Base abstracts for Data Transfer Objects, Data Access Objects, Bean/RMI clients, Application exceptions, and others that can be easily extended and used.
*
Many static utilities that turn many common tasks into coding one-liners (JDBC, Date routines, EJB routines, etc.)
*
A JDBC layer that provides enhanced exception information for easy problem diagnostics and performance tuning information.
*
Collection augmentations and enhancements.
*
Many other generic/useful common utilities.
All utilities in CementJ adhere to the following principles:
*
All utilities strive to be one-liners to save you coding time.
*
No complex or lengthy set-up procedures that cost you time.
*
All exceptions originating from CementJ are Runtime exceptions -- we don't force you into numerous try/catch blocks unless you want them.
*
All arguments are validated with meaningful error messages to reduce the number of derivative exceptions and save you time.
CementJ is featured in the forthcoming book The J2EE Architect's Handbook : How to Be a Successful Architect for J2EE Applications to be released by DVT Press in June, 2004.

JSP dynamischer Inhalt in Custum Tag Attribute : Error
Ich habe beim Einfuegen eines dynamischen Inhalts (Request Time Expressions a la <%= variable %> in einen Custum Tag die Fehlermeldung:
etc erhalten. Hier ein paar andere Links die im Netz zu diesem Thema zu finden waren:
Re: einfache jsp Problem: "c_rt.tld"
Scheinbar hat folgender Eintrag in der web.xml etwas damit zu tun:
#
#
#http://java.sun.com/jstl/core_rt
#/WEB_INF/c_rt.tld
#
#
Mail Reader Servlet / c_rt.tld
=> Lösung:
Entscheident war wohl das einfügen eines speziellen Tags innerhalb der TAG Definition:
(Ich hatte leider Probleme den ganzen XML Code hier in Blogger schoener zu posten, das mit der Textarea hat auch nicht richtig geklappt - leider)

User/PW Protection for MS ACCESS and Java JDBC connections
1) First get a new MS ACCESS database
2) make the database password protected by using the Tools/Security/User-Level Security Wizard.
By doing this a file secured.mdw for example is created
3) Create a User Data Source which points to the mdb file and choose the system database option and select the mdw file there. Enter no user and password in the user data source definition (under advanced options)
4) Connect to the database via JDBCODBC Bridge as usual and enter user and password during getConnection
The important hint for this doing was found at
dBforums - JDBC Microsoft Access
