If it is so urgent please take some time to work out the correct forum for your question, this forum is to discuss the getting started documentation.
Also as this is a JBoss forum not a Weblogic forum it might be helpful if you describe the functionality that you are after rather than assuming that everyone knows what that feature does in WebLogic.
I came to know that there is no folder like APP-INF/lib in JBoss. So the thing that we have to do is, put an entry for all common jars in application.xml as an ordinary java module. It works fine.
