How to install a very specific subversion of Java (JDK/JRE)

rose_bud4201 · 06-12-2008, 05:11 PM

Ubuntu 8.04 (upgraded from 7.10, not clean installed).

On my system, Java 1.6.0_06 is installed by default. In order to compile the software I need to for work, I need SPECIFICALLY 1.5.0_10 (beta2, I believe).

I've used apt-get to install 'sudo apt-get install sun-java5-jdk', in the hope that it would solve the problem, but it installed 1.5.0.15 and my continuing invalid version in .class errors say that nope, it's not good enough.

Sun's website isn't helping. Is there a way, o wise LQ'ers, to tell Ubuntu that I want this very specific version of Java?

Here you can find past releases for any platform.. but I can't see any old beta releases that are available for download :s

Did see 1.5.0_10 here, but like i said - no beta

hope this works out for you

Got it - thanks!

The next question is how to make ant (via Eclipse) use that version. Everytime I compile, it still uses 1.6.0.06, which is the original version installed on my system.

/usr/bin/java is changed:

Code:

[501:laura@alderaan ~]$ java -version
java version "1.5.0_10"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_10-b03)
Java HotSpot(TM) Server VM (build 1.5.0_10-b03, mixed mode)
[502:laura@alderaan ~]$ ll /usr/bin/java
lrwxrwxrwx 1 root root 22 2008-02-03 07:20 /usr/bin/java -> /etc/alternatives/java
[503:laura@alderaan ~]$ ll /etc/alternatives/java
lrwxrwxrwx 1 root root 42 2008-06-16 09:21 /etc/alternatives/java -> /home/laura/downloads/jdk1.5.0_10/bin/java
[504:laura@alderaan ~]$

Eclipse is set to use 1.5 compatibility and is started via

Code:

/home/laura/eclipse/eclipse -vm /home/laura/downloads/jdk1.5.0_10/jre/bin/javaw.exe

but there doesn't seem to be anywhere to set a specific java path. Screenshot of the persistent problem is here for clarification.

Thanks to anyone who can give a hint!
