Having just installed FC4 I have heeded the warning about not using the sun java rpm and followed the instructions and created my own package(s) using the file from the java-1.5.0-sun link under the non-free section at www.jpackage.org. Following the instructions given for building your own files this resuls in 8 rpm files as follows :- java-1.5.0-sun-1.5.0.03-1jpp.i586.rpm * java-1.5.0-sun-alsa-1.5.0.03-1jpp.i586.rpm java-1.5.0-sun-demo-1.5.0.03-1jpp.i586.rpm java-1.5.0-sun-devel-1.5.0.03-1jpp.i586.rpm java-1.5.0-sun-fonts-1.5.0.03-1jpp.i586.rpm * java-1.5.0-sun-jdbc-1.5.0.03-1jpp.i586.rpm java-1.5.0-sun-plugin-1.5.0.03-1jpp.i586.rpm * java-1.5.0-sun-src-1.5.0.03-1jpp.i586.rpm I have installed the ones marked * Would it be benificial to install any of the others.
