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

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?

Answer 1

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")
