Has anyone used a java-based gui to call Juce library?

Hey, nice to meet you all!

I just start using juce for 2 weeks, and a general question occur to me then:
Has anyone used a java-based gui to call Juce library? Or is there any suggestion on the Java / c++ integration?

Well Android is java-based. You just have to get handy with the JNI, which is a pain to use, but does the job.
