I need to know what should be the additional deployment descriptor necessary for EJBs otherthan "application.xml, web.xml and ejb-jar.xml".
That is similar xml file to the "weblogic-ejb-jar.xml" we are using in weblogic server. It is better if someone can provide me an sample code.
for an EJB you need only two deployment descriptors,
jboss.xml (same as weblogic-ejb-jar.xml file in weblogic) file.
The other files you have mentioned, application.xml, web.xml etc are not exactly part of an EJB.
You can do without them also.
It seems yo are migrating ur application from weblogic to jboss!! ;-)
