Using multiple java versions in unix
Hello
we are using java 1.2 in our shell / env
it is also set in the main JAVA_HOME env var ,
but we have also java 1.4 installed , now we need to use new application that uses only java1.4
is there any way to point this specific application to use java 1.4 without changing the global JAVA_HOME env var ?
thanks

You can change the JAVA_HOME to point to the JAVA1.4 everytime you run your new application.
Yes, it will override the existing JAVA_HOME only for that particular shell(tty). Else JAVA_HOME will point to JAVA1.2

Another way is to put JAVA_HOME in a configuration file, if the application reads from configuration files.

If I understand it corectly you are using a global JAVA_HOME environment variable. You could override this in the .profile file of the user account under which the application is running, or create a special user account for this application.

export JAVA_HOME=/path/to/java/bin

This way other applications aren't affected by it.
