I wrote a very simple stateless session bean to test the IDE.
It only has 1 business method and i followed the steps in the java boss IDE tutorial to set up the jndi-name etc and it deploys fine.

Then i wrote a simple client application in java, that is supposed to call that 1 method.
But i get a problem with initializing the Naming Context. i took the method from the o'reilly book"Enterprise JavaBeans" 2002 edition.
it works as follows

public static Context getInititalContext() throws NamingException{
 Properties p = new Properties( );
 try {
 p.load(new java.io.FileInputStream("C:/jboss6/server/default/conf/jndi.properties"));
 } catch (FileNotFoundException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 } catch (IOException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 }
 return new InitialContext(p);
 }

but running the code i get

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(Unknown Source)
 at javax.naming.InitialContext.getDefaultInitCtx(Unknown Source)
 at javax.naming.InitialContext.init(Unknown Source)
 at javax.naming.InitialContext.<init>(Unknown Source)
 at Client_1.getInitialContext(Client_1.java:48)

Yes, jboss6\client\jnp-client.jar is in my classpath.

any idea why else it wont find the class? im desperate :O
