If the data is valid, it sends the user back a redirect to a servlet url to give them the data file generated for their input (It is a CSV file). Right now, I am taking all of the fields from the ActionSupport class and appending them manually to the redirect url so I can have their values in the servlet. This becomes tedious if there are many fields in the ActionSupport class. Is there a way to grab the instance of the ActionSupport class from the servlet? If so, I could eliminate the need to append the fields. I can probably use a session variable to temporarily hold the ActionSupport instance, but it seems there should be a more Struts-centric way to get it. Any suggestions? My first suggestion would be to get rid of the redirect to a separate servlet and serve the CSV response directly from the action. Is there a reason you can't do that? There's no way your servlet can get the action class instance, since action instances are request scoped; the instance no longer exists in the new request the servlet receives. Your options in this case (or any other case where you want to use data from one request in a subsequent request) are pretty much limited to either including the data in the redirect URL's query parameters, as you are doing, storing them in the user's session, as you suggested, or persisting them somewhere else, such as a database.

Laurie: I alyways use a redirect after a form post to avoid the stupid page expired warning if the user hits the reload button. I think we will save the ActionSupport instance in the session and get it back from there. Thanks, Neil -- Neil Aggarwal, (214)986-3533, www.JAMMConsulting.com FREE!
