Re: Java Applet Embedding in Tiger


Hi Scott!  Thanks so much for your reply!

Unfortunately, I'm not in a Cocoa app, but a Carbon app (sorry, I should have mentioned that).  All I need is something really lightweight.  I want to say: Here's an applet, here's a window, run the applet in that window (basically what Applet Launcher seems to do).  For OS 9 I used JManager to do this (I was told, in those days, I was one of probably only three people that used JManager.  Oh such fun! ;-)).  Just to be clear, I can't actually use Applet Launcher (or appletviewer) because I need to do this embedded within my application.  My application has Java byte code that it wants to run as an applet, so it just wants to open a window, and run the applet in that window.  Sometime in the uncertain future, we might want to embed the applet in separate window (a window with other stuff in it), as opposed to it running in its own window, but that's not something I don't need to worry about right now.

I just started poking around in Interface Builder to see about using the "WebView" object it provides, but alas, that only seems to be available for a Cocoa app.  I assume that corresponds to the "WebKit" you mention.

The only reason I mentioned the Java Applet.plugin was that the Apple Java 1.4.2 release notes said that's what to use since there's no JManager anymore and the Java Embedding Framework has been deprecated.  But it sounds like Java Applet.plugin provides way more than I need, from what you said.  Is there documentation for that thing anywhere?  I haven't been able to find any.

So, if you could help me find some way to do what I need (my very lightweight applet-in-a-window) in the Carbon environment, it would be MUCH appreciated.

Thanks so much for your help!

-Eric
