Without this, the old one will still be selected. $ /usr/sbin/alternatives --config java Your java plugin for Firefox is also rather out of date, or confused. Presuming you're on Firefox 3.6 or later, it should be libnpjp2.so for i386 as well as x64: /usr/sbin/alternatives --install /usr/lib/firefox-3.6/plugins/libnpjp2.so libnpjp2.so /usr/java/jdk1.6.0_20/jre/lib/i386/libnpjp2.so 20000 (note, I've used the /usr/java path that the sun -rpm.bin installed to on my Fedora Core 12 system) You may also refer to another howto: http://www.if-not-true-then-false.com/2010/02/howto-install-sun-java-jdk-jre-on-fedora-centos-red-hat/ Your mileage may vary :) Nick Nice list, but you seem to have missed out the final “alternatives config java” step to actually select the newly installed JRE.
