    JBoss 5.1EAP classpath/classloading problem

    Rohit Kamboj Newbie


      I have an JSF-Seam based application which works perfectly on JBoss 4.3. I am facing two issues when trying to migrate this application on JBoss 5.1EAP.


      1. Not able to find messages_en.properties (resource bundle) : The properties file is in the following hierarchy:

           MDU.ear --> MDU.war --> WEB-INF --> classes --> messages_en.properties


          The above works perfectly fine on JBoss 4.3. However on JBoss 5, somehow the application is not able to find the resource bundle.


           So if my messages_en.properties has say the following entry:

           mykey.error=This is a sample message


           The code <h:outputText value="#{messages['mykey.error']}"/> on JBoss 4.3 displays 'This is a sample message' on UI. However on JBoss 5, I am getting 'mykey.error' on UI. Somehow I feel JBoss 5 is not able to load the resource file even if the same is present in WEB-INF/classes.


      If I keep messages_en.properties directly under MDU.ear then it works fine.


      2. I am exporting an excel using seam excel which has a link to stylesheet. On jboss5, the application is not able to parse the path of the stylesheet. Following is the code:


           <e:link URL="#{request.contextPath}/stylesheet/mdu-excel.css"/>


           The stylesheet is kept at MDU.ear --> MDU.war --> stylesheet --> mdu-excel.css


           The above works perfectly on JBoss 4.3. However on JBoss 5, I get the following exception:

           The stylesheet however is available at that path because I can pull up the contents of the css on my browser if I hit http://localhost:8080/stylesheet/mdu-excel.css


      If however I keep the stylesheet directly inside MDU.ear and refer it using "/mdu-excel.css" then it works.


      Please suggest.
