ClassCastException

           Summary: ClassCastException
           Product: Tomcat 4
           Version: 4.0.1 Final
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: Unknown
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: revadir@yahoo.com


I get the following exception when I use getClass().getResource("");  This bug 
happens to be exactly the same as Bug #3855.  I made sure there is only 
instance of jndi.jar (as the resolution for that bug suggested), but to no 
avail.  This works just fine in tomcat 3.2.2.

The code is
    /** meta schema directory */
    private static final String METASCHEMA_DIR =
        QbQueryManager.class.getResource("").getPath() + /*MSG0*/"/metaschema";

This is an attempt to get the real path to a directory in which the .class file 
for the class that has this static field exists. (Refer Bug #3855 again for 
more details).
