> Subject: forcing browser refresh from JSP/servlet
>
>
> It's slightly obscure but my problem is as follows:-
>
> I have a JSP page which allows the browser to submit a query to the
> server
> and populates the page returned with values retrieved from a javabean.
>
> This works fine but as well as refreshing the page after a request I
> also
> want to refresh the browser every time the javabean's properties change.
> These properties can change at any time so I need a way that the server
> can
> force the browser to refresh but using meta tags in the JSP page is no
> good
> since I don't have any advanced warning of when the bean properties will
> change.
>
> As I understand it
>
> 1. an applet can refresh a page in a browser
> 2. a servlet can call a method of an applet using HTTP
> 3. a servlet can pass a request to a JSP page
>
> so I would seem to need some kind of servlet/JSP to applet
> communication.
> The applet doesn't need to do anything except force the JSP page to
> refresh.
>
> Can anyone give me some pointers? Any samples would be particularly
> useful.
