Nirav,
JNDI problems can be resolved by having a
resource –ref smething like :
----Begin------------
<resource-ref>
<ref-name>testbank</ref-name>
<resource-link>testbank</resource-link>
</resource-ref>
--End----------------
in ur code it shd be like -> ……
……ctx.lookup(“testbank”);
Thanks,
Santosh.

Subject: Re: EJB trouble
One of the problems is that you have an
ejb-local-ref from the web app to the ejb. This can only be deployed if
the web app and ejb app are in the same ear.
Thanks david....this is learning for me. I removed the local ref, but now I
think there is something wrong with my code. This is how I am accessing my
bean:
<%
helloWorld.HelloWorld helloBean = null;
try {
javax.naming.Context
ctx = new javax.naming.InitialContext();
helloWorld.HelloWorldHome helloHome = (helloWorld.HelloWorldHome )
ctx.lookup(helloWorld.HelloWorldHome.JNDI_NAME);
helloBean =
helloHome.create();
request.getSession(true).setAttribute("HelloBean", helloBean);
%>
The Bean says : <%=
helloBean.sayHello()%>
<%
} catch (Exception e) {
%>
Error : <br>
<%
e.printStackTrace(response.getWriter()); %>
<%
}
%>
This is the stack trace:

I think there should be some more involved in finding the bean in the
JNDI....or is there something required in the bean code to register it? I am
not familiar with the concept of JNDI. Can someone suggest where I can learn
how to lookup EJBs from?
Thanks in advance for your patience :)

Nirav
