Java EE (Java Enterprise Edition) General Discussion

I'm building a call tracking app wich works in a browser with two frames, the top portion is to enter call information and the bottom portion is to display call information. I have a submit button on the top frame which writes call info to the database and then displays it in the bottom frame. So of course the forms target attribute is "BottomFrame". I then want to display a servlet in the top frame that indacates that the call has been recorded and that the App's status is idle. I can call a request dispatcher and display the iidle status servlet, but i can't get it to display in the TopFrame. Can this be done with the click of one button?
