NoInitialContextException + OC4J + Really Urgent help needed

[Chandu Dharmadhikari]

Hi All

I'm using Oracle Application Server(OC4J) for J2EE. i created an application of Stateless Session Bean on j2sdkee1.3.1, & it is working fine on it. Same Application (an .ear file) i deployed on OC4J. But it is giving an error NoInitialContextException, fails at lookup.

The code is as follows to call beans
<%
InitialContext ic = new InitialContext();
Object ob = ic.lookup("ejb/beans.SimpleSessionBean");
%>

"ejb/beans.SimpleSessionBean" is a JNDI name for session bean

if i used another method
<%
Hashtable env = new Hashtable();
env.put (Context.INITIAL_CONTEXT_FACTORY,"com.evermind.server.rmi.RMIInitialContextFactory");
........
%>
Though i've oc4j.jar in "J2EE_HOME"\lib directory, it throws an error ClassNotFoundException :com.evermind.server.rmi.RMIInitialContextFactory

Application contains a method getEchoString(String):String & an index.jsp page calling a bean's method.

i created ejb-jar.xml manually. The contents are as follows
--------------------------------------------------
<?xml version="1.0"?>

<!DOCTYPE ejb-jar PUBLIC '-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 1.1//EN' 'http://java.sun.com/j2ee/dtds/ejb-jar_1_1.dtd'>

Chandu,
Just a suggestion...
Instead of this:

InitialContext ic = new InitialContext();
Object ob = ic.lookup("ejb/beans.SimpleSessionBean");

try this:

InitialContext ic = new InitialContext();
Object ob = ic.lookup("java:comp/env/SimpleSessionBean");

Good Luck,
Avi.

Hi Avi
Thanks for reply.

Already I've tried these options. Plz tell me how to set classpath for application bcoz this error might be due to oc4j.jar may not be in the class path. And also i want to import some other classes written by me which i'm not able to import.

Thanks in Advance

I may be able to help you further.

Avi.
