Java EE servlet error - duplicate URL pattern

Question

I'm in the process of making a prototype banking application for one of my assignments. I've successfully created the persistence API, EJBs, and all required tables. However, when I create the WebClient for my application and integrate that with the Enterprise application and try to run it, I get the following error:

java.lang.IllegalArgumentException: Servlet [RegistrationPortImpl] and Servlet [RegistrationRequesterPortImpl] have the same url pattern

The WebClient only has the default index.xhtml file on it and I have not yet integrated to managed beans with it.

I just wanted to check if my application would run after the integration with enterprise application before I make any advances.

You can add the entry metadata-complete=true in the web-app tag like this:

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  xmlns="http://java.sun.com/xml/ns/javaee"
  xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
  http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
  version="3.0"
  metadata-complete="true">

This post suggests something similar. This entry disabled the scan for Servlet 3.0 specific annotations and web-fragments in /WEB-INF/lib. See here, here and here.

Maybe you could check the URL patterns in your web.xml and what libraries your app use.
