> I have an EAR that contains multiple WAR files. The first webapp to be accessed works fine. Any web request to the 2nd WAR to be accessed causes the following error:
> WARN [VFSScanner] Error handling item 'login/index.page.xml': java.lang.NullPointerException: Cannot find URL from classLoader for login/index.page.xml, loading from org.jboss.web.tomcat.service.WebCtxLoader$ENCLoader at 1ed964f 
> FileDescriptor.java calls:
>    Resources.getResource(name, ServletLifecycle.getServletContext());
> Which returns a static reference to the ServletContext which is overwritten by the last webapp to be initialized.
>    private static ServletContext servletContext;
>    public static ServletContext getServletContext()
>    {
>       //don't throw an exception if null, because of unit tests
>       return servletContext;
>    }
> The 2nd webapp to be initialized will have a reference to the first webapp's ServletContext.
