Problems retrieving the home interface
Jimmy Chan
Just wondering if anybody would have any clue to the cause of my
problem. Here's the portion of the code that tries to retrieve the home
interface:
java.util.Hashtable properties = new java.util.Hashtable(2);
properties.put(javax.naming.Context.PROVIDER_URL, "iiop://"+
receiverName + ":" + portNumber + "");
properties.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY,
"com.ibm.ejs.ns.jndi.CNInitialContextFactory");
initContext = new javax.naming.InitialContext(properties);
} catch (javax.naming.NamingException e) {
System.err.println("Error retrieving the initial context: " +
e.getMessage());
System.exit(0);
}
// 2. lookup the home interface using the JNDI name
// ---------------------------------------------
try {
java.lang.Object o = initContext.lookup(beanName); // this is the
JNDI name
if (o instanceof org.omg.CORBA.Object) {
// Stops in next line for some odd reason!!!!!!!
commuteHome = (ECARemoteServiceHome)
javax.rmi.PortableRemoteObject.narrow((org.omg.CORBA.Object) o,
ECARemoteServiceHome.class);
}
Here's the error I'm getting when the line "commuteHome = ......." is
executed:
