- by JavaDeveloper
My client class code
Hashtable hs = new Hashtable();
hs.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
hs.put(Context.PROVIDER_URL, "jnp://10.20.52.41:1200");
hs.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
Context context = new InitialContext(hs);
System.out.println("-----");
try {
Example helloWorld = (Example) context
.lookup("Example");
helloWorld.display("HelloWorld");
} catch (NamingException e) {
System.out.println("naming exception occoured");
e.printStackTrace();
}
My session bean code
public class Example implements javax.ejb.SessionBean
{
//method here..
}
