      Description

      When used in an EJB application deployed on Sun app server 8.1 (platform edition
      8.1 build b28-beta), ConfigurationFactory throws a java.lang.ClassNotFoundException:
      org.apache.commons.configuration.Configuration.

      Sun includes Digester in at least one of the jars included with the platform,
      appserv-rt.jar, so presumably Digester is being loaded by the System
      classloader. This makes Digester unable to find classes loaded by the EJB
      classloader (in this case, classes in configuration-1.0.jar) unless Digester's
      useContextClassLoader variable is set to true.

      This patch modifies ConfigurationFactory to set useContextClassLoader to true on
      the digester.
