Dear CS,
When you are tring to deploy your application,i guess due to a network problem the server is not getting connected properly.Please check your <url-pattern> specified and try installing your web-server and deploy your application once again.If there is an initial-context problem then please check your servlet coding.

Two things.

First, when you build the InitialContext, you should use this construct:
Properties props = new Properties();
props.put("java.naming.factory.initial", "com.sun.jndi.cosnaming.CNCtxFactory");
props.put("java.naming.provider.url", "iiop://localhost:3700");
InitialContext initialContext = new InitialContext(props);


Second, you should start your program like this

java -Dorg.omg.CORBA.ORBInitialHost=localhost -Dorg.omg.CORBA.ORBInitialPort=3700 client.SimpleSessionClient
