Hi there,
I need help with debugging the following error that I get on a remote machine. JBoss resides on a different JVM and the client on another redhat box. Here is the error:

javax.naming.NoInitialContextException: Cannot instantiate class: org.jnp.interfaces.NamingContextFactory [Root exception is java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFactory]
at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:652)

And here is my client's getInitialContext code:
public static Context getInitialContext() throws Exception {
Properties prop = new Properties();
prop.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
//prop.put(Context.INITIAL_CONTEXT_FACTORY,"org.jboss.naming.HttpNamingContextFactory");
prop.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
prop.put(Context.PROVIDER_URL,"http://lid32.rhythm.com:8080/invoker/JNDIFactory");
return new InitialContext(prop);
}

The following are in my CLASSPATH on the client side:
j2ee.jar j2ee-svc.jar jbossall-client.jar jboss-client.jar jboss-common-client.jar jbosssx-client.jar jboss-system-client.jar jnp-client.jar log4j.jar

Thanks in advance.
