Exception in thread "main" java.lang.UnsatisfiedLinkError: helloworld

my NEWLY added helloworld function contains this "__Fv" at the end
of the name that is why i think it cannot be found by the java
class.

How (exactly) do you compile the native library? Are you using a C
compiler, or a C++ compiler?

I am using the hp-ux aC++ compiler.


Is the failing method declared with extern "C"? It should be, and it
will be if you exactly obeyed the declaration that javah provided for
you in the generated header file. If the signature of your
implementation differs from that in the header file, the extern "C"
javah provided is no longer helping you.

Functions are all marked with extern "C" and i did obey the
declaration( at least i hope so)
of javah.

The .h file looks like that:

extern "C" {
JNIEXPORT jint JNICALL Java_helloworld
(JNIEnv *, jobject);

JNIEXPORT jint JNICALL Java_ApplModify
(JNIEnv *, jobject, jlong, jlong, jlong);

..... there are more functions

}

I very much appreciate your help Gordon.
Need more code?

A
