An interesting article on on AppFuse: AppFuse: Start Your J2EE Web Apps by Matt Raible. AppFuse tries to make it as simple as possible to build, test, and deploy your J2EE Web application. It virtually eliminates setup and configuration, which are often the hard parts. Tools like Ant, JUnit, […]

Core J2EE patterns, Abstract Factory: unit testing with Struts


During development of your Struts-based web tier, you want to be able to test your page flow, action forms and validation independent of your persistency layer, which may be implemented with any Object Relational framework. That is were the abstract factory design pattern comes in handy. Suppose we want to […]

Useful Eclipse-related links

In Nancy Chen Junhua’s article on Developing Struts with Easy Struts for Eclipse she has some interesting pointers to documents on “Eclipse Aided Development” on IBM’s developerworks. In my experience, the articles found on IBM’s developersworks are of good quality. Articles for Eclipse users in the Open source projects zone. […]

Struts and Resource Bundle problems

admin 1

Working my way through the first chapter of Jakarta Struts Live book, I could not get my own application working, failing at the <bean:message key=”welcome.databaseSelection”/> The annoying thing was that the JSP page containing this statement remained blank! Inspection in the Tomcat log files showed that there was a problem […]

A Practical Guide for Integrating EJB and Struts

admin 1

Playing with EJBs at home and programming with Struts at work recently, I wondered how you would integrate those, preferrably with the Eclipse environment: EJB and the Struts framework each have received plenty of coverage individually, but what about leveraging EJB and Struts together? This tutorial lays out a complete […]

Logging quickstart: Log4j and Jakarta Commons logging

admin 1

Jakarta Commons logging is a wrapper around Log4j (Log4jLogger), the Java native logging system(Jdk14Logger) and the built-in fall-back logger SimpleLog. Depending on which one is on the classpath, that logging system is addressed transparently via the easy-to-learn commons logging API. Recipe:

MySQL, stored procedures and callable statements

The stable 3.x versions of MySQL don’t support stored procedures. Consequently the associated JDBC driver can’t support callable statements.

This […]

Logging with J2SDK 1.4 API or Log4J ?


According to this article: After examining the standard logging API, my opinion is to stick with the log4j package if you are looking for a robust logging implementation. The logging API is adequate, but it is missing many of the features available in log4j. For instance, log4j already has a […]
