I'm modifying a JSP/servlet site that I didn't develop, so I'm kind of new to this. I'm trying to pull contact info from a bean on my site, and I can do that just fine. I need to use it to submit a form on another website's webpage (done in ASP, but I don't think that matters). I wanted to populate the text fields on that external form, but I don't think that's possible, b/c in the source those fields' values are hardcoded like this: value="" If you know of any way to trick it, I'm all ears. Meanwhile, my preference was to populate the fields and not submit it so that users could view the info before submitting, but that's not necessary, b/c the next page is a confirmation page (so I'm assuming I can post the form data from within my Java code and so just take my users straight to that external confirmation page). For another project, I used the Apache Common HTTPClient, but in this case, I'd rather not, b/c I don't yet even know how to compile all the site (I only know how to make changes to the JSPs). I figure it should also be pretty easy to submit a form in JSP, even if it's on another site. Am I right? I'm not sure how to, though--it seems a little bit hairy, especially the part where I need to open up that confirmation page after submitting the form. Do I just use GET or POST to submit a form and have the HREF include target='_blank', or is it a bit trickier than that? If you have a good idea about how to code this, I'd love to see it! Thanks, Stephen

Wow - I have no clue what you are trying to do. Perhaps a better explaination and some sample jsp/asp would help! There are many "tricks", but I don't want to jump the gun and mislead you!

This seems familiar. If I can paraphrase your problem: Your new JSP application wants to send data to a pre-existing application that you cannot change and cannot see its source code. One tricky solution is to make your new application construct the HTTP code, containing your new application's data, and send that (HTTP code) to the external application. Then similarly listen for its HTTP response. That application will see and transmit exactly what it normally does when a person interacts with its forms. But this is very tricky. If your problem is actually that you CAN make a few changes to the old application in order to make your new application communicate with it better, here's another approach. What ever data you need to get from the old form, put it into the session object. Your new application should forward to the old app form so that they then share the same session object. As a result, your new app can get and set values in the session object that the old will also see. - just a humble suggestion.
