    Classcast exeception - Classloading ?

    Axel Tischer Newbie

      Hi

       

      I'm trying to run a webapplication in AS7.3 but getting a strange Classcast exception:

      >Cannot cast an instance of "class de.passd.database.PassdConfig (loaded by instance of org.jboss.modules.ModuleClassLoader(id=55))" to an instance of "class de.passd.database.PassdConfig (loaded by instance of org.jboss.modules.ModuleClassLoader(id=234))"<

      Both classes are deployed in the same war archiv.

       

      The code looks like:

      package de.passd.svn;

      import de.passd.database.PassdConfig;

      ....

      Iterator<de.passd.database.PassdConfig> it = cfgList.iterator();

      while (it.hasNext()) {  

        Object o=it.next();

        de.passd.database.PassdConfig entry =  (de.passd.database.PassdConfig) o;

      .....

       

      The same code is working fine in GF4.0

      I read this Class Loading in AS7 - JBoss AS 7.1 - Project Documentation Editor, it says "The war is considered to be a single module, so classes defined in WEB-INF/lib are treated the same as classes in WEB-INF/classes. All classes packaged in the war will be loaded with the same class loader."

      What's wrong ?
