Hi All,
I'm Using Websphere Application Server 3.5.4. I'm able to succeessfully deploy an EJB, but when I run the following client code It gives me "ClassCastException"
-------------------------------------------------------
InitialContext ivjInitContext = null;
bgc.ipt.ejb.IPTLeasedLinePriceEstimatorHome beanHome = null;
bgc.ipt.ejb.IPTLeasedLinePriceEstimator remote = null;
// Get the initial context
try {
Properties properties = new Properties();
// Get location of name service
properties.put(javax.naming.Context.PROVIDER_URL,
"iiop://bharani_kumar:900/");
// Get name of initial context factory
properties.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY, "com.ibm.ejs.ns.jndi.CNInitialContextFactory");

ivjInitContext = new InitialContext(properties);
Object homeObject = null;
homeObject = ivjInitContext.lookup("bharani");
//System.out.println(ivjInitContext.lookup("bharani").getClass().getName());
beanHome = (bgc.ipt.ejb.IPTLeasedLinePriceEstimatorHome) javax.rmi.PortableRemoteObject.narrow(homeObject,
bgc.ipt.ejb.IPTLeasedLinePriceEstimatorHome.class);

} catch (Exception e) { // Error getting the initial context
System.out.println("Error: "+e);
e.printStackTrace();
}
----------------------------------------------------------------
The following is the exception I get

Error : java.lang.ClassCastException
java.lang.ClassCastException
at com.ibm.ejs.ns.jndi.CNContextImpl.isContextLocalCheck(CNContextImpl.java:1340)
at com.ibm.ejs.ns.jndi.CNContextImpl.doLookup(CNContextImpl.java:764)
at com.ibm.ejs.ns.jndi.CNContextImpl.lookup(CNContextImpl.java:590)
at javax.naming.InitialContext.lookup(InitialContext.java:349)
at EJBClient.main(EJBClient.java:30)
Interactive Session Ended
I have tried setting the classpath Deployed EJB jar file as someone mentioned before. But The problem still exists.
Please Help Me!!!
Thanking you in anticipation,

Try:
ivjInitContext = new InitialContext(properties);
Object homeObject = null;
homeObject = ivjInitContext.lookup("bharani");
//System.out.println(ivjInitContext.lookup("bharani").getClass().getName());
beanHome = (bgc.ipt.ejb.IPTLeasedLinePriceEstimatorHome)homeObject;
because you already have the home interface after you look it up with context.lookup()
Hope it works.

Hi Francisco,
The problem here is, It fails at
homeObject = ivjInitContext.lookup("bharani");
It prints the same line number in Stack trace too. But If I give a message after that line it doesn't print that.
But If I give some arbitrary name, in stead of a JNDI name (ie. if I give ivjInitContext.lookup("bharani765765")), It appropriately throws NameNotFoundException. That does mean that I'm getting the right context and my "lookup" call goes to my EJB server. I dont know what's happening inside, which throws this ClassCastException.
Somebody Please help me.
