call c++ function from java without changing c++ code

I want to use some .cpp class and methods in my java program. For example, I have p1.java that calls method1. method1 is available in p2.cpp and p2.cpp includes p3.cpp. I don't want to change cpp codes...

Is it possible? (and I need .cpp and .header both.)

And is there any alternative better solution? (except java native interface)?

Why don't you create an extra layer between Java and C++ with JNI - effectively you create:

method1_java_cpp_layer( JNIEnv * e, jobject o )
{
    extracted_information = extract_information( e, o );
    method1( extracted_information )
}

And this goes into "java_cpp_layer.cpp".
