    Runtime.getRuntime.exec question

    I have the following

    Process o = Runtime.getRunt ime.exec("java stuff",en);
    where en is -f CH-ResultsDB.. picked that up somewhere,
    anyways
    this code is run in a thread and i would like it to run every hour or so.
    The program that is called is a popupwindow which asks for some information
    from the user which then is send on to a server.
    But the problem is when i run the program by itself so not via the runtime
    command it works fine, but when i run it with a thread it sleeps before a
    user has time to fill out the form and therefore crashes, i dont get a error
    messgae but it doesnt seem to respond anymore...

    Any ideas?

      edit: The program doesnt crash however the window that is called up( the
      form) doesnt respond anymore after i try to send the information. The thread
      runs like normal
      And when i run the program alone it works fine.

          found out some more.... the program which is called crashes when i try
          establish the socketconnectio n. again when i run it by itself it works
          fine... is there a way so that i can have two extends at the end, the reason
          why i have two programs at the moment is becuase one is extends JFrame and
          the other extends Thread...
          Might it have to do with the fact that the thread is alredy asleep? if yes
          how might i prevent for the first program to continue until the called
          program is done?

              not sure I understand all the details
              of your question (might help if you
              post some snippets of your code) but
              just in case your problem turns on
              this point I am wondering if you would
              want to try defining one class to
              extend JFrame and implement Runnable,
              rather than having two classes extending
              JFrame and Thread?

                  He could just use "extends JFrame implements Runnable", then pass the object
                  to a "new Thread(Runnable )" (Sorry, original post is gone)
