So, I removed Suns rpm, reinstalled gcj and installed Suns Java as descriped on http://www.mksearch.mkdoc.org/howto/jpackage-sun-fc3/ (java-1.5.0-sun package from Jpackage). Now I have two java installations under /usr/lib/jvm: java-1.4.2-gcj-1.4.2.0/ java-1.5.0-sun-1.5.0.04/ For learning java swing and for executing java applications that depends on Suns java I want to use java under the path java-1.5.0-sun-1.5.0.04/. For the rest to do with java I want to use java under path java-1.4.2-gcj-1.4.2.0/. For selection I use 'alternatives --config java', but this only works as root. Is there a way to get this also work for a user and not only for root? Is this solution now a good idea or will there be problems, maybe when updating my system with yum? Seems to me that using java under fedora core 4 is a little bit tricky. thanks Olaf
