It’s a J2EE project. There’s a EJB .jar and a webapp .war rolled up into a .ear file. When exploded, the web stuff is under
[Jboss]/deploy/exploded_ear/exploded_war/
We are not using any special launch configuration, and we are using the built-in JBoss4.x server. We set the Default Output Folder under Java Build Path to point at the exploded Jar directory under JBoss and hot-code replace for those classes is working great. Now we just need to get the JSPs to do the same.
