Stanton Finley's page is an excellent resource, but I believe there is an inaccuracy in the Java steps. If you had followed his instructions to the letter, you would have found this: > Current `best' version is /usr/lib/jvm/jre-1.4.2-gcj/bin/java. This is because this command gives Sun's Java the priority of '2' which is less than the default gcj priority of '1420': /usr/sbin/alternatives --install /usr/bin/java java /opt/jre1.5.0_08/bin/java 2 If you want the 'best' version to be Sun Java, then you need to give priority a higher value, such as '1421' like so: /usr/sbin/alternatives --install /usr/bin/java java /opt/jre1.5.0_08/bin/java 1421 For the most part, this is just me being anal-retentive/pedantic, but there have been reported problems with Eclipse hanging if you set up Java as described in SF's doc. 2. The Java plug-in in IBM's J2SDK1.4.2 seems to fail -silently- when I tried using it in Firefox for FC6. There seemed to be an additional plug-in, though, a JNI plug-in that exists in the same directory as the Java plug-in. According to one site, I need to create a symlink for that to Firefox's plugin directory. I tried that, but no joy. I went back to Blackdown's Java SDK 1.4.2. This JVM seems slower than IBM's (not sure about Sun Java because I don't use it for my own personal reasons), is always a version behind, lacks certain components such as a SAX parser, but is the most reliable Java I have ever used. With each new Fedora release, IBM's Java seems to break until the next service release (SR) You may want to try a lower version of Sun Java, or try Blackdown's Java (still 1.4.2). Or if you really want to use Sun Java, you may want to try adding "export LD_ASSUME_KERNEL=2.4.1". I read somewhere that this may work -- or not. I'm not sure whether setting this environment variable may cause your applications to break. I've never used it personally. Regards, pascal chong
