Hi, I have this so far which works Ok but it means the "output" window
opens in a new window/frame and as such cannot be closed by clicking on
the normal close glyph (minimize and maximize/restore work fine) until my
Tomcat server is closed down which does so unwillingly, even by closing
the parent servlet window which opened the "output" window in the first
place. Is there a way to display the "output" window in the current
servlet window rather than in a new window/frame as I think this would be
better? Any ideas why the "output" window won't close properly? Thanks.

} catch (JessException ex) {
ex.printStackTrace();
} catch (Exception ex) {
throw new ServletException(ex);
