change the java in your path. make a symbolic link to the java installation you wish to use.

There are several ways to go:

1. Uninstall the previous (this is NOT necessary!):

2. Use "alternative --configure" to control which (of multiple JDK's) is the default:

3. Simply set your environment to point to one or the other:

Many prefer to do this globally in /etc/profile or $HOME/.bashrc; I think there are advantages in a per-project "env.rc" file. The only "critical" one as $PATH. Other environment variables include
$JAVA_HOME
$JAVA_BIN
$CLASSPATH
etc etc

EXAMPLE LOCAL "ENV.RC":

Quote:

cd MY_PROJECT
vi env.rc

Code:

export PATH=/opt/jdk1.5.0_06/bin:/usr/kerberos/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/home/cole/bin:.
export JAVA_BINDIR=/opt/jdk1.5.0_06/bin
export JAVA_HOME=/opt/jdk1.5.0_06
export JAVA_ROOT=/opt/jdk1.5.0_06
