Simon Kitching commented on BETWIXT-57:
---------------------------------------
Ok, I've made this default to "true". I've also ensured that when set to false,
lookup is relative to the classloader that loaded Betwixt, not the one that
loaded Digester. See r495842, r495843.
> Class loader problem in JBoss version 4.0.4GA
> ---------------------------------------------
>
> Key: BETWIXT-57
> URL: https://issues.apache.org/jira/browse/BETWIXT-57
> Project: Commons Betwixt
> Issue Type: Bug
> Environment: JBoss application server version 4.0.4GA. Probably
> affects most versions of JBoss
> Reporter: Surjit Sen
> Priority: Critical
>
> When using betwixt in a JBoss application, "Class not found" exceptions get
> thrown when Class.forName methods are called in classes
> org.apache.commons.betwixt.digester.ElementRule and
> org.apache.commons.betwixt.digester.ClassRule. Specifically the Class.forName
> method uses the system class loader to load classes and in JBoss the
> classpath normally does not contain the application jar files. The fix is
> very simple. The Class.forName method calls in both the classes were replaced
> with the following code lines in ElementRule and similar changes were made in
> ClassRule as well. This fix ensures that the appropriate class loader is used
> for loading classes and is similar to the fix made in log4j.
> ClassLoader loader =
> Thread.currentThread().getContextClassLoader();
> if (loader == null) {
> loader =
> Class.forName(implementationClass).getClassLoader();
> //Class clazz = Class.forName(implementationClass);
> }
> Class clazz = loader.loadClass(implementationClass);
> descriptor.setImplementationClass(clazz);
