INstallation Question

[Filosofo]

I have install Java 1.3 and I must Install java 1.4 .
Can I install without remove the version 1.3?
Or I must remoive the version 1.3?
What happen if I install without remove the version 1.3?

Please help me

Thanks Filo

Hi,

I think you can install 1.4 without removing 1.3 because the files live in /opt/java1.3 and /opt/java1.4 sub-directories, so they don't step on each other.

Hi,
usually you can have multiple installation, because they rely on different path names /opt/java1.3 /opt/java1.4

You must pay attention to environtment variables, because by default you will have only one of the two java machine avaiable, the first in the PATH.

Apart from that,
let's hear other's comment.

I have successfully installed java 1.4 onto my system which at the time already contained java 1.3 and java 1.2

It installs into /opt/java1.4 directory and runs well. Oracle does not support running on that release. If you are running Oracle, you need to leave java 1.3 installed.

I did not like how it worked and ripped it out several weeks later.

Filo,

As others have said, it installs into different sub-directories, allowing you to test the new version without disrupting the old. We currently have 3 different version simply because I can't get my programmers to finish their testing and migrating. I'm eventually going to have to enlarge /opt, I think.
