I met the same problem.
and the same code runs correctly in a java eclipse.
============= the code ===================
public class MainFrame {
public static void main(String[] args) throws Exception {
Properties props = new Properties();
props.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
props.setProperty("java.naming.provider.url", "localhost:1099");
InitialContext initCtx = new InitialContext(props);
Rankgrade rankgrade = (Rankgrade)initCtx.lookup("RankgradeBean/remote");
}
}
=========== the excepiton ====================
