JNI and package information

Question

Hello guys,
I have created a JNI program.
There is C++ shared Library.
I'm working with Sun Solaris 2.5 and Java.1.3
When I run my program in the same package, there is no problem.
But when I create a package where I find my JNI program, it doesn't run correctly and he says me:
UnsatisfaiedLinkError: createInstance not found
But my native method exist.
example:
in a package A for the main:
import B.*;
import java.lang.*;
class toto {
public toto()
tata cl = new tata();
tata.createInstance();
static void main(String[] args)
toto tt = new toto();
in another package B
package B;
import java.lang.*;
class tata {
tata()
public native void createInstance();
static {
System.loadLibrary(tatalib);
There is an error with this version.
The version with no "package B;", no "import B.*;" and all the code in the same directory is good.
What is the problem ????
Thanks

In your C part, you have to specify the package name in which your Java class is running.
For example:
JNIEXPORT .... Java_a_createInstance(JNIEnv *, jobject ... )
Try that. That was my solution to something similar.
