If the exception is thrown on the call to the native
method, then it's not a DLL finding or loading problem,
but either a construction or JVM restriction problem.

The code you posted looks good in terms of names and
general format.  I have no experience with CodeWarrior,
but if you dump the exported entrypoints in the DLL,
do the Java native method functions show and do they
have the correct names (ie. no preceding "_" or funny
trailing chars)?  Using MSVC++ compiler, this is done
using "dumpbin /exports name.dll".

Where is the class loaded from when it calls the native
method?  If the class has a classloader, the native
method will fail explicitly due to a hard wired check
in the JVM.

From your post, the DLL is loading fine.  If it wasn't
found, the exception would be on the loadLibrary()
call.  And the DLL should be somewhere in the PATH or
one of the dirs searched by default (ie. exe dir, cwd, 
etc).
