This is because Sun's packages are done in a way incompatible with the way the rest of Fedora handles java. This is mentioned in the FC4 release notes. If you want Java RPMs, the ones from JPackage are the best way to go: http://www.city-fan.org/tips/JpackageJava Installing the Sun non-RPM package into /opt is a slightly simpler alternative, as has been mentioned by others.
