Notifying java object from C / C ++ code?

I am wondering if it is possible to notify ( notify()) a java object with native code?

For example, let's say we have a thread in java that is waiting for a signal, as shown below.

void _do_something() throws Exception{
   synchronized(__lock_){
      __lock_.wait();
   }
}

Then is it possible to notify an object __lock_from its own code ?! Should I pass the object __lock_to c-code? as and how the C code calls the method notify(). Any help is appreciated. Thanks in advance.

This is very convenient for inline code. You need to use JNI though ...
