[news.eclipse.tools.jdt] UnsatisfiedLinkError when invoking native metho

[chan@xxxxxxxx (chan)]

My config: Eclipse 3.1M5, JRE 1.4.2.07 + WTP, Win xp.

I created a project with a default pkg and added a java file that invokes 
a native method (sayHello) found in a C-dll.  This works fine.

When I move the java file to some other pkg and run the executable there, 
then I start getting :

     java.lang.UnsatisfiedLinkError: sayHello.  

The library seems to load because if I remove the dll I'll get a different 
UnsatisfiedLinkError.  For some reason the method can't be resolved from a 
pkg that is not the default pkg.

The header file for the native method was generated using javah and the 
signature of the native method follows the convention 
Java_classname_methodname.

Any ideas as to why moving the java file from the default pkg to a 
different pkg causes the native method to go unresolved?

Thanks in advance.
Chan.
