Hi All
I am facing a problem while trying to get the Initial Context. I am using
OpenEJB as a local server i.e the
org.openejb.client.LocalInitialContextFactory class to get the Initial
Context but i get this exception. Stack Trace follows
Exception Caught in InitialContext
Javax.naming.NamingException: Attempted to load OpenEJB. Cannot embed
OpenEJB. Exception: java.lang.Exception Cannot initialize OpenEJB. OpenEJB
has encountered a fatal error and cannot be started: The Assembler
encountered an unexpected error while attempting to initialize:

The code for ClientForHelloWorld.java File is:
package com.niit;
import javax.rmi.*;
import javax.naming.*;
import java.util.*;
public class ClientForHelloWorld
{
public static void main(String[] args)
{
System.out.println("Hello World!");
try
{
Properties p= new Properties();
// p.put(Context.INITIAL_CONTEXT_FACTORY,
"org.openejb.client.LocalInitialContextFactory");
//i had tried both the above commented statement and
the next on uncommented statement
p.put("java.naming.factory.initial","org.openejb.client.LocalInitialContextF
actory");
//i had even tried to specify the openejb.home
parameter in diffrent ways: Using System.setProperty and by specifing it in
Properties object
//
p.put("openejb.home","c:\\openejb\\openejb-0.9.2");
Context ctx=null;
try
{
ctx = new InitialContext(p);
//Here i stuck in the exception
}catch(Exception e)
{
System.out.println("Exception caught
in Initial Context");
e.printStackTrace();
}
//Lookup the bean using it's deployment id
Object obj = ctx.lookup("HelloWorld");
System.out.println("After Context Lookup");
//Be good and use RMI remote object narrowing
//as required by the EJB specification.
HelloWorldHome ejbHome = (HelloWorldHome)
PortableRemoteObject.narrow(obj,HelloWorldHome.class);
//Use the HelloHome to create a HelloObject
HelloWorld ejbObject = ejbHome.create();
//The part we've all been wainting for...
String message = ejbObject.helloWorld();
//A drum roll please.
System.out.println( message );
} catch (Exception e)
{
e.printStackTrace();
}
}
}
The code for my Bean Class is:
package com.niit;
public class HelloWorldBean implements javax.ejb.SessionBean
{
private javax.ejb.SessionContext cntxt;
public void setSessionContext(javax.ejb.SessionContext ctx)
{
cntxt=ctx;
}
public javax.ejb.SessionContext getSessionContext()
{
return cntxt;
}
public void ejbCreate() throws javax.ejb.CreateException
{
}
public void ejbActivate()
{
}
public void ejbPassivate()
{
}
public void ejbRemove()
{
}
public String helloWorld()
{
return "Hello World!!";
}
}
Please help me out of this exception......
Thanks and Regards
