Common problem - you're picking up "Gnu Java" (which is there by default) instead of "Sun Java" (which is what you really want).

Strong suggestion:
1. Deinstall Gnu Java (Gnu Gcj and Sun Java *can* co-exist peacefully, but having them together might complicate your life)
2. Download and install Sun Java
3. Re-run your install (this time, you should be happy)

Here's are links that might help:
