Hello
I have the following problem. In Java I have a class named nlo, it has
as its members three objects of type nla (say nla1, nla2, nla3). The
class nla has a method setx(). I would like to access the method
nla.setx() from C++ using JNI. The arguments of my native function is
something like this (generated by Javah):

JNIEXPORT void JNICALL
Java_br_com_vrtech_JEqs_JNLPSolver_solveNLPnative
 (JNIEnv * env,
 jobject obj_this)

I have done the code bellow but I can go on since I don't know how to
access  a method of an object that is a member of another.

   jclass cls
   jmethodID mid;
   jfield fnlp1;

   refe  = env->PushLocalFrame(20);

   cls = env->GetObjectClass(obj_this));

   fnlp1 = env->GetFieldId(cls, "nlp",  "methodsignature");

How to get a reference to nla1 or nla2, or nla3. I hope I made myself
clear.

                                Thanks
