Can I install 2 different java version (v1.4 and v1.6) in parallel ? Co-existence possible?

[Jason Stacy]

A software installation (from Oracle) requires the presence of java (j2ee) v1.4

No, it does NOT accept a newer version 1.6 of java(j2ee) which is already
installed on my computer.

So I have to install java 1.4 in addition to the previous v1.6 on my computer.

is this possible? Can both installation co-exist ?

Or do they interfere each other?

Which environment variable decides which installation is used:

JAVA_HOME
or the order of the java "bin" directories in the
PATH
environment variable ?

Hi
Yes you can have two versions of jdk/java in your system.
Both the installations can coexist.
Regarding which version to be used , just check if the software you
are using (oracle etc..)
allows you to choose the jdk version.
You can also set the PATH variable to point to the required jdk
version.
