On ubuntu 'which java' will return /usr/bin/java which is a symlink to
/etc/alternatives/java on ubuntu
This mechanism allows multipe jre/jdks to be installed. You can list,
and set what the version of java is being used with update-alternatives
update-alternatives --list java
The output should look like something like this depending on versions
installed.
/usr/lib/jvm/java-1.5.0-sun/jre/bin/java
/usr/lib/jvm/java-6-sun/jre/bin/java
/usr/bin/gij-4.2
/usr/lib/jvm/java-gcj/jre/bin/java
/usr/bin/gij-4.1
You can then set which one to use as follows
sudo update-alternatives --set java /usr/lib/jvm/java-1.5.0-sun/jre/bin/java
Afterwards java -version returns
java version "1.5.0_13"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05)
Java HotSpot(TM) Server VM (build 1.5.0_13-b05, mixed mode)
I hope this helps.

John
