[jboss-jira] [JBoss JIRA] Commented: (JBAS-5646) @EJB does not work in servlet

    [ https://jira.jboss.org/jira/browse/JBAS-5646?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12452937#action_12452937 ] 

Gerbrand van Dieijen commented on JBAS-5646:
--------------------------------------------

Hello, I got the error too when using JBoss 5.0.0.GA

I could work-around the problem by adding a mappedName parameter to the @EJB annotation with the JNDI name:

Bean snippets:

@Stateless
public class MyBean implements MyBeanInterface {
...
}

@Local
public interface MyBeanInterface {
...
}


MyServlet extends HttpServlet { 
    @EJB(beanInterface=MyBeanInterface.class,mappedName = "MyBean/local")
    private MyBeanInterface myBean;
..
}

With the mappedName the bean was injected succesfully in my servlet.

> This was not an issue in 5.0.0.Beta4.  I pulled the trunk to get the fix for another bug and this cropped up.  Basically, I declare an interface POJO and prefix it with @Remote.  I then declare a stateless EJB which implements that interface and prefix it with @Stateless.  Finally, I create a servlet and prefix an attribute declaration of the interface type using @EJB.  None of the annotations have any parameters.
> See the Forum reference for the log dump (first post) as well as the java code (third post).  I apologize if this is a duplicate...I see some other issues which look close, but I was not sure.
> Work-around:
> Add 'mappedName="EJB3Test1/CoverageWCBean/remote"' to the @EJB annotation in the servlet.  This gets me past the "java.lang.IllegalStateException: Resolution should not happen via injection container" problem, but then this problem crops up:
> 23:41:28,159 ERROR [FieldBeanProperty] failed to set value jboss.j2ee:ear=EJB3Test.ear,jar=EJB3TestEJB.jar,name=CoverageWCBean,service=EJB3 on field private ic.poc.wc.CoverageWC EJB3TestServlet.wc
> java.lang.IllegalArgumentException
> 	at sun.reflect.UnsafeObjectFieldAccessorImpl.set(UnsafeObjectFieldAccessorImpl.java:63)
> This problem is then worked around by setting CallByValue=true in the Naming service (jboss-service.xml) and then it works (EJBTHREE-983 might be related to this problem).  Note that I tested this in GlassFish and it all works fine with just the annotations without any parameters as it did under 5.0.0.Beta4.
