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. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4072614#...
