Susan, I wrote a applet that uses a servlet and used the following method to pass the form data to the applet. What the class does is takes the data passed to it by using a property and url encodes it, it then appends the jsessionid if it needs to and posts it to the servlet.
Hope it help.

You could always just do it the easy way and generate a page with just a form and the form data filled in then put a javascript at the bottom of the page that submits the form. The user doesn't notice and it's simple.

Try using the HttpURLConnection class in the java.net package. Before opening a connection you need to call the setRequestMethod() function and set the method to POST. -----Original Message----- From: Susan M. Orndorff [mailto:[EMAIL PROTECTED]] Sent: Monday, October 08, 2001 12:32 PM To: JRun-Talk Subject: Way to post form data without a form? I am using an applet to call a servlet named OrderPage which returns an html page. To do this I am using URL newUrl = new URL("https://hostname.com/store/OrderPage?Item=teaCustomer=Nancy";) getAppletContext().showDocument(newUrl, "_self"); When I do this, the parameter string (?Item=teaCustomer=Nancy) shows in the address window. I do not want these parameters to show. I have been told there is a way to post data like a form would, but without using a form, that is, to do it automatically from within the program, without ANY user interaction. Does anyone know how this is done? Thanks for any help...
