JNI callback and jar

[Mic]

Hi all,

I have been dragged with this problem for 3 days... I wrote
a JNI bridge function that does call back to a function
inside a callback class. The java application is archieved
in a jar fiile...

location -
caller in jar: one\two\three\caller.class
callback in jar: one\two\three\callback.class

To be able to callback at the JNI, FindClass need to locate
the callback class... so the class name is passed by using
its "full qualified" name, as I thought...

"one.two.three.callback"

However, FindClass returns NoClassDefFoundError

I have tried to set the classpath environment...

When you invoke FindClass, you need to spell the classname like this:

(*env)->FindClass(env,"one/two/three/callback")

i.e. don't use dots like in your example.

This can only be a guess. Next time, post real code!
