Netscape talking to Java App(lett)

I am looking for a way to send all/any Netscape Events (as pressing the Back Button or selecting an item from the bookmarks) to a Java Applikation or any Programm for that matter, regardless of the loaded page.

Please note the direction! I do know about the remote mechanisms availiable.

Also I am not talking about a way to manipulate the browser
in such a way that it will do anything for me. Quite to the contrary am I trying to manipulate another program by pressing any of Mozillas buttons. Like a hook in most of emacs functions: whenever a file is loaded and you want to add a new functionality, you add your function to the call-list for (find-file)

An Applet can't tell the browser what it should do, except for the few defined API calls (showDocument(), showStatus()). What you need is JavaScript, ie. pseudoJava that is interpreted and executed by the browser itself. It can be used to do quite a bit with the browser, but I'm not sure it can be used to communicate with an applet. There's a topic for JavaScript right here, so you'll probably get a better answer there.

My answer wasn't too well formulated, after the second reading. I will try again.

You cannot use Java to tell the browser anything, except for those few standard calls. This also means that you cannot tell the browser to "send me an Event whenever this widget is used". This is actually, a bit stupid, since a lot of intelligent agents and other statistical programs could then be created, if the applets could access information such as how the user navigates, what pages are loaded etc.

But this is unavailable, possibly because of security issues. The only information you can get it locate other applets in the page and communicate with them.

I for one haven't dwelled in JavaScript, but if anything could be used to extract the information you want, that should do it. But as for relaying that information to an applet - I'm sceptical.

Sorry for not being able to give you the answer you're looking for.
