Note that these libraries have been built against GDAL 1.4.4.
Where do you have placed the DLLs to let them work during your first test?

On Windows, we have sometime noticed similar issues on DLL native libs
loading. Not sure what is happening when this occurs. (Be sure that all
required libraries are together with these DLLs (A check with "Dependency
walker" may be helpful)).
A solution could be putting them on your JDK/bin being sure that the same
libs aren't somewhere on folders linked by your PATH env.  (Be sure you
don't have old GDAL Libs somewhere hidden on your machine)
This could be helpful to do some initial testings. See my next feeddback
about JNLP.

We are working on creating a web start application involving other native
libraries (not GDAL related).
Therefore we will handle native DLLs loading and some feedbacks on this
topic will come in the near future (we are working on it this week).

Cheers,
Daniele
