Re: About the Cocoa-Java bridge

There's an article here about getting the JavaBridge to work for arbitrary Cocoa classes.
Its for Jaguar/Project Builder. Perhaps it'll still work on Panther/Xcode, with tweaking.

Please go file a bug on this. Lots of people want it to be supported, but there's no sign of Apple doing this yet.

In AppleScript Studio, one can use the 'call method' command to call any method
of any object in Objective-C, and not just for Cocoa classes but any code, even
Objective-C code you have written yourself. For example:

call method "sharedWorkspace" of class "NSWorkspace"

call method "numberWithInt:" of class "NSNumber" with parameter 10

It would be wonderful if there was something equivalent in Java. JNI can do
this, but you have to write a dylib, load it, and all this fun stuff. Currently
we have the Cocoa-Java bridge, but it is limited to the classes that have been
wrapped, and not all of them have been, and specialized APIs like the Address
Book API or the NSAppleEventManager class are not available through Cocoa-Java.

I don't know why bridging from AppleScript to Objective-C is a matter of one
command, when in Java it's a matter of a set of classes. Maybe it's because the
Cocoa-Java bridge wraps classes instead of just implementing a way to call them?
