[jbossseam-issues] [JBoss JIRA] Updated: (JBSEAM-4316) Classloader cannot find XML files in multiple WARs

[Reind D (JIRA)]

     [ https://jira.jboss.org/jira/browse/JBSEAM-4316?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Reind D updated JBSEAM-4316:
----------------------------

    Attachment: jbseam-4316.tar.gz


1) tar -xzvf jbseam-4316.tar.gz

2) Deploy jbseam-4316.ear to jboss 5.0.0.GA.

3) Access http://localhost:8080/a/

Note the following error in the server log:

WARN  [VFSScanner] Error handling item 'index2.page.xml': java.lang.NullPointerException: Cannot find URL from classLoader for index2.page.xml, loading from org.jboss.web.tomcat.service.WebCtxLoader$ENCLoader at 1193d1f


Notes:
a) This ear packages a jboss-seam.jar that includes the patch attached to this ticket.
b) Very minimal configuration in *xml
c) no class files, only 3 xhtml files.

> 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.
