Using JNI to execute a java jar from a C++ program, using g++ or eclipse

Question

I\'m trying to call / execute a java jar from a C++ program.

Here are the options I\'ve found so far:

Answer 1

Usually you have to add some kind of platform specific directory as well like on Linux:

g++ -I /usr/lib/jvm/jdk1.6.0_34-x86/include/ -I /usr/lib/jvm/jdk1.6.0_34-x86/include/linux Hello.cpp

because a few macros (like JNICALL) are set up there. Hopefully that'll fix the jni.h error cascade.

EDIT: Still stuck? Try:

JNI_CreateJavaVM(&jvm, (void**)&env, &vm_args);

It'll at least get past the compilation problem. I don't know if it'll work, since I've not tried this before.
