What should I specify in the yum install command? I have CentOS 5.8, fully updated, but it still has Java 1.6.

Thanks, John

Hello John,

That's because this is the current stable version supported by RedHat in its enterprise offerings. Not sure when OpenJDK 1.7 will land, if at all. Fedora 17 has 1.7 already.

Generally speaking, using software coming from a repository configured in yum makes it a lot easier to maintain the system and keep the packages up to date.

It is a bad habbit, especially in an enterprise environment, to deploy software to machines in a fashion where you hardly have an overview which software version is being installed and without a proven method to keep the systems updated with new versions for fixing bugs and security issues.

Yes. However, my BrailleBlaster project may require Java 1.7. I suppose I can obtain it from Openjdk and install it manually. I should probably uninstall Java 1.6 first. After I install Java 1.7, will subsequent use of yuum update mess up that installation?

Thanks, John

You have a few of choices here...

CentOS 6.3 includes openJDK 1.7 as a tech preview (and as such it will get security updates etc) so that TUV's customers can test against Java7....

Actually it is now fully supported and not a preview ... they messed up and then fixed the announcement:

http://rhn.redhat.com/errata/RHEA-2012-0981.html

Fedora 17 includes openJDK 1.7 as a 'supported' package (and indeed does not even have 1.6 in the repositories)...

Install the Oracle Java package from Oracle's site and set JAVA_HOME etc etc appropriately to use it.... you may need to set up alternatives to make sure the Oracle Java takes preference if you install a package that results in a dependancy chain that pulls in openJDK.

This will get you java-1.7.0-openjdk on CentOS-6.3:

yum install java-1.7.0-openjdk
