Using your second below method but without including the parameter operation
in the
query string should accomplish. So the code would look like:
return new ActionForward(mapping.findForward("success").getPath() +
"?versionId=" + versionId);
Any calls to request.getParameter("operation") should return null after
that.

It isn't clear what you are trying to achieve; however one thing that jumps
out is your use of request *attributes* as opposed to request *parameters*.
When you append a URI thusly:
foo?operation=bar&baz=gak
you are providing *parameters* and not attributes.

Subject: reset a request parameter to null
Hello, all,
What is the easiest way to set the request paramter to null?
I have OneForm and TwoForm, both of which have a field of "operation". After
OneAction is finished, the request will be forwarded to TwoAction. The wierd
thing is that I cannot reset the "operation" parameter. I tried in the
OneAction:
request.setAttribute( "operation", null );
OneForm.setOperation( null );
request.removeAttribute( "operation" );
return new ActionForward( mapping.findForward( "success" ).getPath()
+ "?operation=&versionId=" + versionId );
All above approaches do not work. The last one comes really close to set
operation="". Does anybody have a decent way to set the parameter to null?
Thanks. Denis
