Hi Mark, Thanks for the comments. I will check out the GNU Classpath. However, I am confused. Does it matter what the size of the external jar or library is? Doesn't your program just import the API's that you tell it to from the library (and presumeably those superclasses that it descends from)? It doesn't try to include them all does it?
