Using Java JTree navigation menu & frames in a browser: is there a way to track the pages being displayed in
ther target frame?

I would like the JTree to reflect where
in the site the user was at any minute,
even if they use the browser button. Have experimented with applet & cookies,
but got alot of strange errors using the
netscape.javascript.* package.

Any thoughts or assistance would be
appreciated and compensation is possible
for complete solutions.

according to my own experience ALL the browser JavaVM implementations use ClassLoader per URL - so if you load both applets from the same Codebase / Archive you can share static variables etc.
another option is AppletContext.getApplet() which is somewhat tricky (because both applets may be loaded from different classloaders, so you can exchange only 'standard' Java objects ...

but it seems that you'll always have problems if the user has opened several browsers to the same site ... maybe some JavaScript will help you ...

well - I can't give you code solution, but I'll help you if you have any problems ... that's an interesting question :)

what about using 1 x 1 applets inside all pages that will inform the main applet about page name ... it will work fine if there is only one browser window pointed to that site (otherwise, you'll need some JavaScript)

Hi Heyhey,

Is inter-applet communication
reliable in your experience? If
so then this may be a solution.

Do you know how applets on different
frames would locate each other, that's
not browser specific?

Thanks in advance,
Bill Rowe
