item on VC to generate testhello. dll. Alternatively, right-click header files and select add files to folder to find the files under the JDK directory respectively. For example, in my JDK directory, set C: /program files/Java/jdk1.6.0/include/JNI. h, C:/program files/Java/jdk1.6.0/include/Win32/jni_md.h, which is the same as importing a head file.
4. Copy testhello. dll in the debug folder of the VC project to the folder where testhello. Class is located.
