blank page returned from validate

I'll preface this by saying that i am extremely new at using struts. Finally got around the various error and display issues and now i'm just not getting anything. when i submit the form i get a blank page (/testing.do), i was under the impression that it would return to the page indicated in the input parameter of the action-mapping. The following is the code that i'm using, any input would be appreciated.

thanks for your help

ok... figured it out... if you are going to override validate make sure you aren't being a moron and overriding the wrong one... override the one that takes javax.servlet.http.HttpServlet as an argument. Secondly, something that really irritated me initially, your form elements must start with a lower case character and if you are using a ActionForm it will automatically try to compare parameters (introspection) by prefacing your form elements with get/set and changing your first character to uppercase... as a result make certain that you aren't thinking of that in your validate and just focus on the form element names (i didn't change them when i changed the forms)....

hope this might help someone...
