    Seam app scans components.xml included in other ears?

    Guillaume Jeudy Master

      Hi,


      I'm using Seam 2.0.1.GA with JBoss 4.2.2 GA. I have 1 same app (EAR and 1 WAR bundled) and a separate EAR (non-seam app).


      Both ears use scoped class-loading with the following jboss-app XML config snippets:


      <jboss-app>
            <loader-repository> 
            seam.jboss.org:loader=seam-rdm
            </loader-repository> 
      </jboss-app> 
      



      <jboss-app>
            <loader-repository> 
            a.b.c:loader=rdl-clientapp
            </loader-repository> 
      </jboss-app>
      



      Both EARs include a JAR that contains a seam.properties and components.xml containing a seam component with the same name. When Seam loads it detects the components.xml in both EARs and fails with an exception:

           ... 138 more



      The code in Initialization detecting the components.xml files is the below:


       resources = Thread.currentThread().getContextClassLoader().getResources("META-INF/components.xml");
      



      Is this expected behavior? I was under the impression that both EARs were completed isolated from each other, to me it seems like the contextClassLoader is shared between both EARs...


      Has anyone come across this problem before ?
