[Configuration] XMLConfiguration cannot read from XML from jar

           Summary: [Configuration] XMLConfiguration cannot read from XML
                    from jar
           Product: Commons
           Version: 1.0 Beta 2
          Platform: All
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Configuration
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: jromanda@infophase.com


In the current RC1 codebase, the XMLConfiguration class cannot read an xml 
configuration file packaged in a jar file. The PropertiesConfiguration class 
handles this correctly using an InputStream rather than a File object, but the 
XMLConfiguration does not.

Here is a patch for XMLConfiguration that lets you put XML files into a jar 
file.
