Hi Dharmendra, Thank you for the answer. I tried the way you said, but the "response" variable is non-final too. I think that my apporoach is not right, because I don't see the connection between the web page(the jsp page) and the frame. When something happens in the frame, I can't find a way to tell the web page to do something. The JSP is first shown to the user and after that the Frame. I don't know how to get it work, maybe i'll try to make the frame as applet, the applet has the funcionality to communicate with the page in which is loaded. This boolean function, that I call when the button is pressed, reads from the hdd, and I don't know whether I can use it within the applet, but I'll try.
