[jboss-user] [Beginner's Corner] - Error using UnifiedInvoker

[maciekcom]

Hi,

I've configured UnifiedInvoker for JNDI as dscribed here:

http://www.jboss.org/community/wiki/JNDIOverHTTPWithUnifiedInvoker

My jndi properties:


  | 
  | java.naming.factory.initial=org.jboss.naming.HttpNamingContextFactory
  | java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
  | java.naming.provider.url=http://localhost:8180/unified-invoker/JNDIFactory
  | 

My web.xml:

<?xml version="1.0" encoding="UTF-8"?>
  | <!DOCTYPE web-app PUBLIC
  |    "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
  |    "http://java.sun.com/dtd/web-app_2_3.dtd">

  |         <description>A servlet that exposes the JBoss JNDI Naming service stub
  |         through http. The return content is a serialized
  |         MarshalledValue containg the org.jnp.interfaces.Naming stub. This
  |         configuration handles requests for the standard JNDI naming service.

  |         <url-pattern>/JNDIFactory/*</url-pattern>

  |          </config>
  |       </attribute>  
  |    </mbean>
  | </server>

When I'm trying to acces JNDI I got:
