I have jboss 4.2.1 GA with Eclipse 5.5 and trying to run the calculator example given on the jboss site. I have created the bin and here is my client:
public static void main(String[] args) {
try {


Context context=new InitialContext();
AdviceRemote bean = ( AdviceRemote) context.lookup("com.andy.ejb3.AdviceRemote/remote");
System.err.println(bean.getAdvice());
} catch (NamingException e) {
e.printStackTrace();
}

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

If I use something like,

properties.put("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
properties.put("java.naming.factory.url.pkgs","=org.jboss.naming:org.jnp.interfaces");
properties.put("java.naming.provider.url","localhost:1099");

Context context=new InitialContext(properties);

I get:
javax.naming.NoInitialContextException: Cannot instantiate class: org.jnp.interfaces.NamingContextFactory [Root exception is java.lang.ClassNotFoundException:


Please help!
