[jboss-jira] [JBoss JIRA] Commented: (JBAS-6054) @EJB injection in JSP fails for local interface

[Ondrej Medek (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBAS-6054?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12477400#action_12477400 ] 

Ondrej Medek commented on JBAS-6054:
------------------------------------

This issue is still in 5.1.0GA. It annoying when the EAR name changes, one has to change all mappedNames in the JSP pages.

> I will attach a sample for this problem.
> To verify the code:
> The attached EAR contains EJB, Web and ApplicationClient projects, one EJB "GeometricModelBean" with remote and local interfaces. The web project uses injection, the application client performs a JNDI lookup.
> The JSP  tries to inject a local and a remote interface in "GeometricModelTest.jsp" (http://localhost:8080/StatelessWeb/GeometricModelTest.jsp)
> <%!
>   @EJB()
>   GeometricModelRemote geometricModel;
>   @EJB()
>   GeometricModelLocal geometricModelLocal;
> %>
> The local interface injection will fail with this exception (from server console):
