[SOLVED] Emerge jdk-1.6 and jdk-1.5 on the same machine?

[john.newman]

Hello

# java-config -L

*) IcedTea6-bin 1.10.3 [icedtea6-bin]
2) Sun JDK 1.6.0.26 [sun-jdk-1.6]

I have the sun jdk 1.6 installed. I'm not using it for anything yet, but I'm expecting to need it at some point due iced-tea lacking those com.sun packages that people tend to use It's really unfortunate.. Anyway, in addition to those two versions, which I must keep as-is, I also need to install an old copy of sun-jdk-1.5u22 for a certain application that is far from compatible with jdk-1.6.

What is the best way to do that with portage? Leaving java out of it for a second, how do I get two versions of the same package? If I add an entry to package.mask the newer version is gone with a --depclean right?

The goal is:

# java-config -L

*) IcedTea6-bin 1.10.3 [icedtea6-bin]
2) Sun JDK 1.6.0.26 [sun-jdk-1.6]
3) Sun JDK 1.5.0.22 [sun-jdk-1.5]

Then I will create a "tomcat" user, and set its user vm to option 3, leaving system and most other users at option 1. That is a very nice feature , this java-config tool has been quite helpful so far. I just can't figure out how to get two versions of the same package with portage...

OK I think I figured it out. You generally cannot have two versions in the same package "slot", because version A would most likely clobber the files from version B.

Also jdk-1.5 has been retired from the portage repositories (good), it is only available in the java overlay

The java team was able to slot the jdk's so you just need to find the old 1.5 ebuild and put it in your local overlay (there are instructions for that) and install it. Use java-config to select the java runtime you need then run the app.

You want to look in the attic

Ah, you figured it out. Good. I didn't know they kept it around in the java overlay.
