Just to clarify - Kaffe finds and loads the native library without
troubles, but the C library has trouble finding my custom Java
classes, which are located in phidgets.jar, unless I put phidgets.jar
in the same place as rt.jar - I would have expected that adding
phidgets.jar to CLASSPATH would make this jar file (the classes that
it contains) visible to the C library (findClass).
