Look up EJB in JNDI


I am trying to use an EJB from a web dynpro application. The EJB is given a name as "MaterialBatchBean" as follows:












When I try to look up this EJB using the following codes, it always complains about the incorrect path:

InitialContext ctx = new javax.naming.InitialContext();

MaterialBatchHome mbHome = (MaterialBatchHome) javax.rmi.PortableRemoteObject.narrow(ctx.lookup("java:comp/env/ejb/MaterialBatchBean"),MaterialBatchHome.class);

Does anyone know what is wrong here? Your help is appreciated!

    Hi Hart,

    You can check the exact path of your EJB from the Visual Admin. In the Visual Admin, go to service EJB Container -> Beans. Then drill down to your ejb project and your ejb. You can then see the path from the JNDI Name field on the right.

    Also, rememeber that you need to set the reference to this EJB from your Web Dynpro project properties when you lookup ejb from your code implementation and not using model.

      Hi guys,

      Looks like I am the one who should apologize...

      No fighting or offending please, at least not on a word by which nothing bad was really meant.

      It is very hard not to agree with Detlev's viewpoint of helping others through SDN forums. I believe this is what all the other SDN members, or we say, SDN friends think.

      Back to my previous question, I did have an impression that the prefix "java:comp/env" is not needed anymore, but this is only my assumption, not a conclusion made from Detlev's posting.

      With Vladimir's note, I am now much more clear about this.

      Thanks again my friends!
