Qt Jambi, Trolltech releases Qt for Java

Hardingfela writes "Trolltech has released a preview of its long awaited Java bindings for Qt 4. "Qt Jambi technology integrates Qt with the Java programming language, providing new possibilities for both Java and C++ programmers. This technology enables Java developers to take advantage of the powerful features of Qt from within Java Standard Edition 5.0 and Java Enterprise Edition 5.0" More information on the Jambi press release and tech details in the Jambi whitepaper.

Now only if GTK+ decently supported Windows operating system versions, actually used native style/widgets, and weren't so mind-numbingly bad at performance. The native Java 6 Swing GUI stuff is actually faster than GTK+ now, despite still being in beta (try it yourselves and see!). "GTK+ enthusiasts" tend to be rabid about 'everyone should use this!', but it's overwhelmingly lackluster in performance and memory usage. People should make their own analysis and look into alternatives, not just take the GTK+ word for it. Qt is very well performing, very well behaving (it effectively wraps around native platform widget/engine stuff), and looks like a dream. GTK+ is (disclaimer: in my personal opinion) almost as bad as old X11 apps that just use ancient versions of Motif or Athena. GTK+ just doesn't blend in very well, and (again, opinion) leaves everything to be desired over more robust and compatible libraries.

Been Using This

I've been playing around with this for a few hours. Running some of their demos, things seem very snappy, and the applications look better than most Swing/AWT applications. I've always been fond of the way Qt works, and I think it will be nice to have the option of using it with Java.
Of course this is still a developer preview. After playing around with it for about 4 hours, I still can't get an application to launch, except for the demos that it ships with. This is probably due to my own ineptitude, but if I'm having trouble with it, I'm sure other developers will as well. I suspect that once there is an official release, things will be made easier (or the documentation will be made clearer) and there won't be so many problems.
PS: If anyone has played around with this and had success, maybe you can help me out. I created a project in eclipse, added the qtjambi.jar file into the classpath, set the PATH to qtjambi-linux-preview/bin and LD_LIBRARY_PATH to qtjabmi-linux-preview/lib, whenever I try to launch an application, I get
failed to load library: 'qtjambi'
Exception in thread "main" java.lang.UnsatisfiedLinkError: no qtjambi in java.library.path
...
Anyway, I think it will be really nice once I can figure out how to use it properly.
