One of the developers on my Team came up to me with the folloing scenario, whilst deploying module a webapps to weblogic, one of them would not deploy due to an error "could not istantiate DataSource <datasource name>" ... altough this DataSource isn't declared in that specific app.

 

It could be I am pointing out the obvious, altough If I'm not the following should save you some time.

I am mentioning this for on a large Cluster like ours which consists fo several machines, build & deploy lifecycle can take over an hour-three depends on the environmens site & location (automation or not ...), so why spend valuable time on it ?

 

Scenario:

EJB 3 Interceptors tutorial
  • This is a short tutorial for EJB 3 interceptors, and its purpose is to explain the concept of an interceptor and what is it good for.
  • The content of this tutorial is a shrinked version of a tutorial posted here: http://www.mastertheboss.com/en/jboss-server/177-ejb-interceptors-in-depth.html
  • which also contains code example.
  •  
  • EJB 3.0 interceptors allow you to add functionality to business methods of your session bean without modifying the methods' code.
  • An interceptor is a method that's executed before any of the bean's business methods are invoked.
  •   
  • How does it work ?

Calling EJB3 SLSB with Spring : what syntax ?

I find the Spring 2.5 manual (chapter 18) unclear regarding the syntax that EJB3 clients need to declare in order to be able to call a remote SLSB EJB3.
Should we use a SimpleRemoteStatelessSessionProxyFactoryBean (like I was used to doing with EJB 2.1) ?

Or should we use the <jee:remote-slsb> tag ?

JBUG 4 - EJB 3 Development in Jboss environment

EJB 3 is one of the most important innovations introduced in Java EE 5.0. EJB 3 promises to simplify enterprise development, abandoning the heavyweight EJB 2.x, facilitate test driven development, and focus more on writing plain old java objects (POJOs), without sacrificing the mission of enabling business application developers to create robust, scalable, standards-based solutions. This lecture highlights what EJB 3 has to offer and key points of using the EJB 3.0 API with JBoss environment..
