Janardhan, welcome to Java Ranch!
If you deploy an EAR, the EAR should have a structure like this:
xxx.EAR
+-- xxx.war
+-- xxx.jar (contains EJBs, for example)
+-- META-INF/application.xml (references both xxx.jar and xxx.war)
The EAR can be deployed as either an archive file, or as an exploded directory. Either way, it must have the .ear extension.
If this does not help, post the content of your EAR (use "jar -tf xxx.ear"), the contents of your application.xml file, the full path for the deployed EAR file or exploded directory, and the URL you are using in the browser.
