EJB查找失败

Question

Am trying to lookup an EJB and when am doing so, getting error as
While trying to look up comp/env/ejb/UserImpl in /app/webapp/BSWeb/131433158

RestImpl: `

@Produces("application/json")
@Consumes("application/json")
@Path("UserSession")
@Stateless 
public class UserSessionManagerImpl {
@Context
HttpServletRequest httpServletRequest;
@Context
HttpServletResponse httpServletResponse;
@POST
@Path("retrieveUserProfile")
public RetrieveUserProfile retrieveUserProfile (RetrieveUserProfileRequest request)
{
try {
InitialContext ctx = new InitialContext();
IUserSessionManagerIntf manager = (IUserSessionManagerIntf) ctx.lookup("java:comp/env/ejb/UserSessionImpl");
replyVO.retrieveUserProfile();
} catch (Exception namingException) {
namingException.printStackTrace();
}

My EJB

@Stateless(name = "UserSessionImpl", mappedName = "ejb/UserSessionImpl")
@Local
public class UserSessionImpl implements IUserSessionManagerIntf {
retrieveUserProfile(){
....
}

Can some one help on this. Am using this in a rest implementation. On ejb lookup it fails

Answer 1

Have you tried to put:

@EJB(name="ejb/UserSessionImpl", beanInterface = IUserSessionManagerIntf.class)

on your UserSessionManagerImpl class? mappedName property is vendor specific. You should not assume that you'll find your bean with mapped name under java:comp/env . Instead you can use my above suggestion or global JNDI names (or vendor-specific functionality - check in docs).
