I have an application in which: Frame1 issues the request. Servlet does it's thing. Frame1,Frame2,Frame3 need to be updated based upon Servlet data. I don't know how to get multiple frames to be updated by one servlet. Any ideas will be helpful I'm at a loss right now. Thanks in advance.
Here is a note on that which I clipped from the comp.lang.java.programmers newsgroup. It was originally written by Phil Hanna. "Yes, it works. <FRAME SRC="/servlet/MyServlet"> will invoke MyServlet at its doGet() method, just as it would if it were in a hyperlink that was clicked, like <A HREF="/servlet/MyServlet">click here</A>. If the servlet is not already loaded, the init() method is called first - no different than any other servlet invocation. A neat trick is to have the *same* servlet generate the <FRAMESET> and each of the frames: <FRAMESET> <FRAME SRC="/servlet/MyServlet?frame=1" NAME=... > <FRAME SRC="/servlet/MyServlet?frame=2" NAME=... > ... </FRAMESET> Check the "frame" parameter at the top of the doGet() method. If it is null, generate the <FRAMESET> block, otherwise, generate frame 1, 2, or whatever. --- endquote
