How to specify class name in environment or system property

Question

Hi,
Iam learning ejb. I was practicing the stateless session bean. I wrote a sample hello world application. While executing the client am getting the following error.
{color:#ff0000}Exception in thread "main" javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
at javax.naming.spi.NamingManager.getInitialContext(Unknown Source)
at javax.naming.InitialContext.getDefaultInitCtx(Unknown Source)
at javax.naming.InitialContext.getURLOrDefaultInitCtx(Unknown Source)
at javax.naming.InitialContext.lookup(Unknown Source)
at hw.HelloClient.main(HelloClient.java:20){color}
My Client program:
{color:#3366ff}package hw;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.*;
import java.util.*;
public class HelloClient {
public static void main(String[] args)throws Exception {
Properties prop = System.getProperties();
Context ctx= new InitialContext(prop); {color:#800000}// {color}{color:#800000}(Line no :20) here only error is pointing{color}
Object obj = ctx.lookup("HelloHome");
HelloHome home = (HelloHome)javax.rmi.PortableRemoteObject.narrow(obj,HelloHome.class);
Hello hello = home.create();
System.out.println(hello.hello());
hello.remove();
}{color}
please suggest me a solution.
note: iam using eclipse ganymede and jboss app server

Hi,
You need to create a ejb-jar.xml and jboss.xml files to deploy the application on the servers.
Also, put these lines of codes after getting System Properties.
prop.put(Context.PROVIDER_URL, "iiop://localhost:[port_no]");Thanks,
