You can't do that, first of all, unfortunelly, you can only return one object in a method call (maybe you can do that using references in Java, i'm not sure if this will work). What you can do is create a wrapper function, that wraps all the elements in the stl vector class to your newly created java.util.Vector java class.

Example:


...

vector vec;

...

jclass clazz = (*env).FindClass("java/util/Vector");

jobject obj = (*env).NewObject(clazz, (*env).GetMethodID(clazz, "", "()V"));

...

for (int n=0;n
{

   char* str = (char*) static_cast(vec[n]);

   ...

   jstring _str = (*env).NewStringUTF(str);


   (*env).CallVoidMethod(object, (*env).GetMethodID(clazz, "addElement", "(java/lang/Object)V"), _str);

   ...

}

...

return obj;
