jpackage, JDKs and Ant

[Steve Loughran <st...@apache.org>]

Having just upgrade to Suse9.2 wierd and wonderful things have happened 
to my java setup, like the java1.4.2 JDK has moved somewhere, and now 
all the java commands are in /usr/bin, symlinked through 
/etc/alternatives to what looks like a new version of 1.4.2. 
Also,JAVA_HOME is mapped to the JVM home, not a JDK:

 > echo $JAVA_HOME
/usr/lib/jvm/java


Does anyone know what is going on here? Is this jpackage or a new Sun 
layout system? I think the former, as adding java1.5 SDK to the mix 
doesnt bind javac to the new location.

What should I be doing to move up to Java1.5?

On the ant side of things, who has played with ant installed via 
jpackage? Are the scripts different? What are the mechanisms for people 
to add new stuff to the lib directories, given that a root-installed 
system wont let people do that? Do you have to run ant -lib ~/somedir , 
or is that all automatic?

Ick!

I would say do what is normally done, define JAVA_HOME and PATH in your 
.bashrc file, except
place the $JAVA_HOME/bin at the start of the $PATH rather than at the 
end of the path.

..
..
export JAVA_HOME=/usr/java/jdk1.5.0
export PATH=$JAVA_HOME/bin:$PATH

jpackage, I guess.

Probably install <http://www.jpackage.org/rpm.php?id=1291> (see the
rebuilding instructions).

I haven't, but I used to help them syncing with our stuff.

They used to be current with our CVS HEAD scripts rather than Ant
1.6.x, but I haven't checked lately and unsubscribed from the jpackage
list during my last vacation.

~/.ant/lib just like you'd do with plain Ant.
