EJB Session bean is not bound in JBoss 5 in EAR packaging

Question

I have a dynamic web project which I deploy in EAR format on JBoss 5. Using ant I compile and deploy the ear file on application server. If I deploy EJB and war (client) independently then everything work but when i try to package in ear session bean does not bound. My EJB code and client(Web) are in same project I do not have Independent EJB modules in project. I tried adding jar out of business interface in WEB-INF lib and even in lib directory of ear file but nothing worked. I want to know If EJB jar is not in the class path and how to set order of modules in ear file?

Have you tried injecting the EJB by adding @Stateless(name="manageStudentSessionBean") to the EJB module instead of just @Stateless and in your servlet use the annotation @EJB(name = "manageStudentSessionBean") above the entry private ManageStudentSessionBeanLocal manageStudentSessionBeanLocal = null; — JGlass
Thanks for help but sadly it did not work. Does ejb module goes into the class path? You know when I try to deploy war and ejb module independently by adding ejb module in the class path to war then it works. — Virendra Singh Rathore
I dont believe it needs to go into classpath. Do you have a web.xml in the WAR's WEB-INF folder, as per the linked article "For the injection to take place in a web module, your web.xml should use the 2.5 version of the web-app xsd" - can you try creating that file with the XML they show in the important section? — JGlass
@JGlass I have added web.xml structure in the question and yes it uses 2.5 version. I think client should have the ejb module in the class path in order to deploy and compile. — Virendra Singh Rathore
Understood on the web.xml. I believe with the JBoss class loader, the EJB Module would already be in the classpath - are you referring to adding it as a class patch entry in the web apps META-INF/MANIFEST.MF file? None of my projects have this listing, but a number of them were in the process of being upgraded to JBoss 7. What output in the server.log file is shown when you deploy the application? — JGlass

When we package an EAR file out of EJB modules then lookup method for the client changes slightly. We can always check it in the console what path we should refer to for injection.Look up method for EJB injection in Servlet for EAR packaging would be something like this.

@EJB(mappedName="YOUR_EAR_NAME/ManageStudentSessionBean/local")
