While recently reading through a leading national newspaper, I happened to notice a slick, full-page advertisement for a new enterprise-class server. Made by a leading hardware manufacturer, it was one of those N-way Intel Xeon rack-mount systems that are in a whole league by themselve...
A 'StackOverFlow' message is usually indicative of an error in the application code of the user, an error in the Java Virtual Machine, or in BEA WebLogic Server itself. This message is usually seen right before a Java Virtual Machine core dump or the WebLogic Server process just 'goes ...
Another discussion based on a weblogic.developer.interest.transaction posting this month. It's a newsgroup that always proves to be a good source of information for the world at large when it comes to transactional behavior (and a good source of inspiration for me when the article time...
Mercury Interactive's LoadRunner is a leader in the performance-testing market. Its ability to create large volumes of data is legendary, and its ability to monitor the systems being tested provides great value. The J2EE Transaction Breakdown Diagnostics Module, LoadRunner, brings deta...

Workflow and state machines are, as argued in my earlier article, 'State Machines and Workflow' (WLDJ, Vol. 3, issue 1), complementary implementation strategies for process-oriented applications. The state approach is a powerful abstraction for the succession of milestones found in man...
The rising business trend toward using open source software platforms has brought an increase in the number of critical applications deployed on Linux and BEA WebLogic. For many organizations, in fact, WebLogic deployments are their first major Linux installation.
The novel Dune, by Frank Herbert, a classic in science fiction, is littered with great references and quotes. One such quote is: 'Knowing there's a trap is the first step in evading it.' With this in mind I can't help but think of the future for BEA WebLogic. The trap I refer to is the...
Web applications are an important part of the Java 2 Enterprise Edition (J2EE) platform because the Web components are responsible for key client-facing presentation and business logic. A poorly designed Web application will ruin the best business-tier com-ponents and services. In this...
