I am using the ParameterMap in request in an authentication mechanism.
Therefore I need to do the following:

add a mapping of parameters to the request.getParameter(). I do the following:

import org.apache.catalina.util.ParameterMap;
...

      System.out.println("ParameterMap is a: "+
request.getParameterMap().getClass().getName());
        try{
          ParameterMap map = (ParameterMap)request.getParameterMap();
          map.setLocked(false);
          map.putAll(values.getParameterMap());
          map.setLocked(true);
        }catch(Exception e){
          e.printStackTrace();
        }

This gives the following output:
ParameterMap is a org.apache.catalina.util.ParameterMap
And a ClassCastException in this line:
        ParameterMap map = (ParameterMap)request.getParameterMap();

So it seems that they reference to two different class-definitions, but I
am using the same catalina.jar everywhere. (included it in the WEB-INF/lib dir)

If I put catalina.jar in the WEB-INF/lib dir, then the above error is
reported, else a ClassNotFoundException is thrown.

I'm using tomcat-4.1 and found the class in the catalina.jar file. Where
else is it?


Thanks
