Class name from jclass in JNI

Question

This is probably a daft question that reveals a lack of understanding of JNI. I\'m writing a C++ program that encapsulates the Java VM: I\'m calling functions within the VM usin

Answer 1

The jclass instance is your object on which a method will be invoked; you'll need to look up the getName method ID on the Class class, then invoke it on the jclass instance using CallObjectMethod to obtain a jstring result.

So in short yes, you just call the getName function and look at the jstring result.

EDIT

(error handling elided)

JNIEnv* env = ...;
// substitute your desired class's specifier for "java/lang/Class"...
jclass cls = env->FindClass("java/lang/Class"); 
jmethodID mid_getName = env->GetMethodID(cls, "getName", "()Ljava/lang/String;");
jstring name = env->CallObjectMethod(cls, mid_getName);
