Hi, I'm installing FC4 now, and find that FC4 uses Jpackage Java by default instead of Sun Java. The Jpackage is based on Java 1.4.2, too old for security reasons and seems not recommended. More exactly, the redhat's comments about Java looks like self-confusing at Java section at http://fedora.redhat.com/docs/release-notes/fc4/: --------------------------------------- 6.1.8. Java Package Recommendations Fedora Core 4 users are advised not to use the Java RPM provided by Sun. It contains Provides that conflict with names used in packages provided as part of Fedora Core 4. Because of this, Sun Java might disappear from an installed system during package upgrade operations. Fedora Core 4 users should use either the RPM from jpackage.org or manually install the Sun Java tarball into /opt. Sun Java 1.5+ is recommended for stability purposes. --------------------------------------- in short, there are two confusing requirements above: 1, Java 1.5+ 2, Rpms from Jpackage.org( but the version is 1.4.2 until now.), not Rpms from Sun. Any ideas? Thanks a lot. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
