Java SE (Java Platform, Standard Edition)

Instead of installing the whole JAI there's a new plugin available for the new 1.4 Image I/O API. This plugin is in beta version as of Oct 16th, 2002 (so quite new) but it gives our application some basic BMP support that we were missing.

We're deploying our application through JWS, and I'm having troubles deploying this plugin successfully with it. It contains 3 jar files:

clibwrapper_jiio.jar
jai_imageio.jar
mlibwrapper_jai.jar

And 1 native dll:
clib_jiio.dll

When the app runs standalone I have had 2 configuration choices:
1) Embed the plugin directly into the JRE1.4 directory. The 3 jars would go into the /ext directory and the dll into the /bin directory.
2) Better, the 3 jars were added to the classpath, and the library path was updated to include the dll.

The problem is that JWS gets a little more complicated and I can't trace how the loadLibrary() is being called. I was wondering if anyone has managed to deploy these successfully through JWS, and what was the configuration used in the JNLP for this.

Is it better to make these files an extension?
