links on ejb2, ejb3, jms integration layer practical examples.

What do you mean by saying "integration layer"? do you mean the code that connects (integrates) EJBs and JMS servers? If yes, then I do not think that the connection between these system should be in their own layer.

I am looking for practical good examples, best links on ejb2, ejb3, jms technologies preferably using eclipse and jboss application server. please advise

I cannot advise if you don't tell me what you mean by "integration layer".

i read as java provides client technologies, server technologies, integration technologies to solve business problems.

I thought  integration technologies includes ejb2, ejb3, jms etc where i am not very strong yet. So I am looking for good links, practical examples on those technologies. i may be wrong in calling them integration layer.

With the term integration they probably mean SOA, BPEL and workflows. These are higher level languages which you basically model and programme the flow by using specific tools and by dragging and dropping icons. There are several tools that do this, for example search for WLI (Weblogic integration) or Oracle JDeveloper to have an idea what I am talking about.

Oh. I am looking for some more links like below to practice
