- Extremely basic JNDI question 2007-08-09 - By dbronk

I'm almost ashamed to ask such a basic set of questions, but I'm simply having
problems. I'm pretty new to JBoss, been using just Tomcat. What I'm doing is
creating a datasource and placing a custom pojo bean into jndi. And, I want
these to be only accessible by certain web contexts. In Tomcat, this really
could not be any easier. I simply do the following in the server.xml...
<Context path="/myApp" ... >
<!-- Datasource -->
.... all the normal datasource params ...
<!-- My Bean -->
Now to use the datasource normal Spring stuff. To get my RPSClient object I
need only:
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
RPSClient rpsClient = (RPSClient) envCtx.lookup("rps/RPSClient");
Done!
Okay, how would I do the same for JBoss? I have successfully got a datasource
going in jboss jndi, but it is at application server level, not context level.
I've had zero success in placing a simple custom java object (a config object
really) in jndi.
My main issue with the datasource is that after I war up my application it is
named MyApp.war. Great, works fine. But after working on the war, we want to
deploy it to QA so we simply copy/paste the war file to MyAppQA.war, then
MyAppUAT.war, etc. So now we may have several different versions running in
the same JBoss instance. Since each are looking for jdbc/TestDB they all get
the same database. This is bad. With tomcat since we defined the datasource
in the context, we pointed each (same name, but context sensitive) to a
different db. done!
Thanks, and sorry for what I hope to be a very basic and easy thing to do.
