Hi,
I am running WSAD 5.1.1. I created a entity bean with a local home interface and i try to call it from my web module.I defined the EJB local reference in the Web Deployment Descriptor
<ejb-local-ref id="EJBLocalRef_1098372394984">
<ejb-ref-name>ejb/XMLMsgs</ejb-ref-name>
<ejb-ref-type>Entity</ejb-ref-type>
<local-home>com.msgejbs.XMLMsgsLocalHome</local-home>
<local>com.msgejbs.XMLMsgsLocal</local>
<ejb-link>XMLMsgs</ejb-link>
</ejb-local-ref>

and i am trying to access this bean from the web module.When i use this code
Context initial = new InitialContext();
Object objref = initial.lookup("ejb/XMLMsgs");
XMLMsgsLocalHome home = (XMLMsgsLocalHome)objref;

It gives me this error
============================
avax.naming.NameNotFoundException: Context: localhost/nodes/localhost/servers/server1, name: ejb/XMLMsgs: First component in name ejb/XMLMsgs not found. Root exception is org.omg.CosNaming.NamingContextPackage.NotFound: IDL mg.org/CosNaming/NamingContext/NotFound:1.0

===========================================
and i also tried using this

Context initial = new InitialContext();
Object objref = initial.lookup("local:ejb/XMLMsgs");
XMLMsgsLocalHome home = (XMLMsgsLocalHome)objref;

( I read somewhere that with WSAD you have to prefix it with local: )
but then i start getting the following error..
=======================================================
javax.naming.NameNotFoundException: Name "ejb/EmailMsgs" not found in context "local:".

Hi Tarun,
Try to prefix the lookup call with a "java:comp/". This could solve your peoblem.

initial.lookup("java:comp/env/ejb/XMLMsgs");

Let me know if this helps.
