LiveConnect and XUL Runner on Mac
Mike Desjardins
I am trying to use LiveConnect to call some Java functions using LiveConnect
on OSX. I've done some googling and it seems a bit ambiguous whether or not
this even works anymore - I understand there was a lot of code cleanup
around Mozilla 2.x and LiveConnect. Complicating things is the fact that
Apple insists on shipping its own version of Java. But I'm hoping that this
should still work.
I've tried the basic recipe from the Mozilla site:
var clazz = java.lang.Class.forName("com.getbuzzbird.myClass",true,loader);
var method = clazz.getMethod("myMethod",[]);
method.invoke(null, []);
and I've even tried just a simple
var fooble = new java.lang.String("Fooble! Fobble! Foible!");
and both result in xulrunner's unceremonious death:
MacBookPro:~/_play/buzzbird> ./bang.sh
### MRJPlugin: getPluginBundle() here. ###
### MRJPlugin: CFBundleGetBundleWithIdentifier() succeeded. ###
### MRJPlugin: CFURLGetFSRef() succeeded. ###
JavaVM: requested Java version (1.5) not available. Using Java at
"/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home" instead.

Any ideas? If LiveConnect doesn't work, is there another way that I can
call into Java code from XULRunner without LiveConnect?
Thanks,
