RE: Struts - Not instantiating Action class.
Hi How multipart/form-data is handled by Struts? My speech application is sending 2 data, one is String and other is binary data (wave file). All these exist in request parameter. When strut workflow is initiated using getRequestDispatcher() does not seem to giving same request parameter. The request parameter does not contain multipart data. Since speech application does not have any view (UI), I am not able to understand how will I ask Strut to set my ActionForm with individual multipart data using setXXX methods. Any suggestion ?

Sashi, What I would do to get around all this is just create your regular actions and such. Then in the JSP that you are calling just forward to the action needed. Something like this in the jsp will do the trick. %@ page language=java % %@ taglib uri=http://jakarta.apache.org/struts/tags-logic; prefix=logic % logic:redirect forward=processAction/ Then although you invoke a jsp you automatically are pushed into the struts workflow. Process action can then do whatever with the request params that you need to do. Alternatively (I cant remember if logic:redirect loses the request params) you can do this in the initial JSP. %@ page language=java % % req.getRequestDispatcher(processAction.do).forward(request, response); % or, a third solution: write a servlet filter that specifically is mapped to your initial JSP, and in that filter forward to the processAction.do Of course in all of these processAction.do and processAction should be renamed to whatever you have in your actionMappings. At any rate one of those three should get you to your goal.

RE: Struts - Not instantiating Action class.
Hmm 1) Why can't it use the XX.do of struts? Its just a resource as far as an external system is concerned. 2) How do you know the action is not instantiated? Are you getting an error message in tomcat? Can you send that along if so. Without an error message I would be want to think that the action is being instantiated, you are just not seeing the results you expect. 3) Have you tested your action with some type of unit test to make sure it is really working? A pretty good example of how to test struts actions can be found in Matt Raible's equinox (it's a minimalistic webapp for training vs appfuse which is for production use).
