Hi All,
My environment: wsad 5.1.1 J2EE 1.3
I'm trying to run this scenario for test purpose:
Servlet -> Messaging Bean -> EJB Session bean
The servlet starts the the Messaging Bean using a Connection factory and queue.
In the web-deployment descriptor I have declared them as refererences.
This works fine.
I get the messaging bean to start, but then I get an exception in messaging bean
doing lockup for the Session Bean.
In the EJB deployment the 2 EJB beans are declared.
I'm confused over how I should do a lockup to the session bean from the messaging bean
1. Should I create a new InitialContext ?
Context ctx = new InitialContext();
2. I have tested with this:
Context ctx = new InitialContext();
String name = "ejb/jmstest/ValidationBeanLocalHome";
Object objref = ctx.lookup(name);

and this:
Context ctx = new InitialContext();
String name = "java:comp/env/ejb/jmstest/ValidationBeanLocalHome";
Object objref = ctx.lookup(name);

Help regarding this deeply appreciated.

Now I am super curious what sports would be like if we allowed drugs and tiny ads.
