I am migrating my application from Websphere to JBoss.
My whole application is in app folder.(I have defines csc as env variable which points to my app)
Can anyone tell me where I can spceify classpath of my application in configuration files in JBoss. Like in websphere I sepecify in variable,server,library and resources.xml's to different jars or DB connection in my application folder.So in Jboss what are the corresponding files or do I need to create new xml's.


You might want to start with the JBoss documentation.
It's quite comprehensive and tells you what all the files are and how they work.
