    JB6 + JSF1.2 class loader or config problem?

      Hi All,

       

      I'm migrating an application from JB 4.2 to JB6 and have noticed some issues using Mojarra 1.2 and facelets.

       

      I deploy my app as an .ear archive, and it contains (among other things) 3 different war files. Each .war file uses facelets, and each one declares a .taglib.xml file.  The application deploys just fine to JBoss.

       

      The problem I'm seeing is when I go to the context mapped by B.war for the first time it parses the facelets tags, but it is also parsing the .taglib.xml file from A.war and C.war. The taglib for A.war uses a <handler-class> for one of its tags, and this causes an error to be thrown by B.war since the class specified isn't contained in its classpath. If I change the build for B.war to include the class being called in A.war's taglib things work just fine with no errors.

       

      Here is the error I see when I visit the context of B.war:

      A.war is "PermitExpress.war", and B.war is "PEMobileWeb.war". From the above you can see when I visit the B.war context it is parsing the taglib from A.war.

       

      Additionally, both A.war and B.war use Richfaces, while C.war doesn't. However, when I visit the context of C.war for the first time it gives errors trying to parse all the RF and A4J taglibs:

      As with B.war, in the case of C.war if I update the build to include the richfaces jar files in WEB-INF/lib for C.war then I dont' get the errors, but this is a bit ridiculous since C.war doesn't use richfaces.

       

      I should also note that although I get these errors in the log files everything seems to work just fine, it just clutters up my logs.

       

      So I'm not sure if this is due to a problem with my configuration or if it is a class loading issue with the JSF deployer? I've tried changing the classloader isolation value in JBOSS_HOME/server/<server>/deployers/ear-deployer-jboss-beans.xml but changing that value has no effect.

       

      Can anyone tell me what is wrong here?

       

      Thanks in advance!

          I think you've run into this issue:

          https://issues.jboss.org/browse/JBAS-7600

           

          This is a problem with the legacy facelets implementation.  We try to supress the error message because it doesn't actually cause any operational issue.  But it looks like yours got through the filter we added to jboss-logging.xml.

            <!-- Limit the verbose facelets compiler -->
  <!-- Also suppress error with legacy facelets (JBAS-7600) -->
  <logger category="facelets.compiler">
     <level name="WARN"/>
     <filter>
        <not>
           <match pattern="Error\sLoading\sLibrary.*jsf-libs/jsf-impl"/>
        </not>
     </filter>
  </logger>

           

          So to work around, either add to this filter or upgrade to JSF 2.

            Thanks, Stan. I'll play around a bit with the logging config and see if I can get it filtered out.

              Just to follow-up, I followed Stan's suggestion and changed the filter to read

               

              {code:xml}<match pattern="Error\sLoading\sLibrary.*"/>{code:xml}

              and now I don't get the errors in my log files.

               

              Thanks again for the tip, Stan!
