This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I have had experience running java almost on any platforms(win32, win ia64, aix, linux, solaris sparc or x86, irix, hpux) and they are all the same (except ; vs : on path separation). Is java installed and is in your path? If yes, just do a java -jar runme.jar. If it is not installed, just install it , it's just an executable that will extract itself which you can download from sun's site. If I didn't answer your question, can you be more specific on your question? [ March 19, 2006: Message edited by: Ed Tse ]

Maybe in /etc/profile ?

I don't think JAVA_HOME needed to be set in your profile. A default setup usually have /usr/bin pathed and a softlink is created as /usr/bin/java. If you want to install a new java 1.5.0, just go download it and put it in some where and recreate a softlink that points to your new java directory.
Fun factor of Solaris x86 is not much for me, as I don't find a solaris useful personally. If you want to get a feel for the *nix, I would recommend a linux which I use regularly (not for this assignment) Given that, I do have a vmware image for solaris x86 for testing purpose for this assignment.

Java under Solaris and Java under Linux are almost the same. The main difference is that (In My Humble Opinion), the conventional place where the JDKs get installed is a little saner in Linux than in Sun's own OS.
JAVA_HOME is not even used by Java itself - it's just a convention that many Java apps have taken as a locator for the JDK to be used. Tomcat and WebLogic are two such apps.
CLASSPATH of course, is always popular. But in a lot of my stuff it's empty, since I get my class path from other sources.
