Hi guys... I've been searching this forum and tried different things to solve this problem, but no luck at all. I'm gettn this exception:

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(NamingManager.java:640)
at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:243)
at javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:280)
at javax.naming.InitialContext.lookup(InitialContext.java:347)
at example.cmp.client.MyClient.main(Unknown Source)

What I've tried to do is the following:

1o.) insert these two lines in my main class:

System.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
System.setProperty("java.naming.provider.url", "localhost:1099");

No luck

2o.)
My client jar file is the following:

MyClient.class
jndi.properties
Manifest.fm

inside my Manifest I have included the following:
Manifest-Version: 1.0
Created-By: Apache Ant 1.5Beta3
Main-Class: example.cmp.client.MyClient
Class-Path: jnp-client.jar jndi.jar log4j.jar

but no luck at all...

what am I doing wrong?
