Hi Andy, I am still not sure if the way I package and deploy EJB 3 ear file is correct. EJB 3 has done away with ejb-jar.xml, but there are other xml files like application.xml, jboss.xml, jboss-app.xml, jboss-web.xml....and so on..... here is the exploded structure of my EAR file: | tmp60740MyEjb3.ear-contents/ | ->META-INF/ | ->application.xml | ->jboss-app.xml | ->MANIFEST.MF | ->MyEjb3-exp.war/ | ->META-INF/ | ->MANIFEST.MF | ->WEB-INF/ | ->jboss-web.xml | ->web.xml | ->index.jsp | ->MyEjb3.war | ->MyEjb3.jar | | MyEjb3.jar when unzipped, further has: | ->META-INF/ | ->MANIFEST.MF | ->persistence.xml | ->com/ | ->mustafa/ | ->ejb3/ | ->HelloWorldBean.class | ->HelloWorldLocal.class | Please let me know if the location of XML files or anything else is wrong. btw, I do not see any use of jboss.xml ?
