使用C ++创建的VM从Java调用C ++函数

Question

I have an native C++ application that creates a JVM (JNI_CreateJavaVM()), which executes a method in a specified class. I now want to call C++ functions from java using JNI. Is it possible to avoid System.loadLibrary() or do I have to create an extra dll just for JNI calls?

Answer 1

Your native C++ application is PE executable without JNI symbols exported. That means you can't mix your JNI method in your native executable, in order to call C++ functions from Java, you have to create another dll and load it with System.loadLibrary .
