Installing Java 1.6 on CentOS 6
Java 1.5 is the default Java version you get when you ask yum to install it on CentOS. However, several applications need 1.6 in order to run. Just follow the next steps to install it.
Remove Java 1.5
1yum remove java-1.5-*
Install the rpmforge repository
1cd
2rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
Check if you have a 32 or 64 CentOS version
1uname -a
For 32 versions (i686) download and install the following repository
1wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.i686.rpm
2rpm -Uhv rpmforge-release-0.5.3-1.el6.rf.i686.rpm
For 64 version (x64) download and install the following repository
1wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
2rpm -Uhv rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
Install Java 1.6
1yum -y install java-1.6.0-openjdk
If the rpmforge repository is not enabled (it should be, but just in case) try the following command instead
1yum -y --enablerepo=rpmforge install java-1.6.0-openjdk
Check your Java version
1java -version
2
3java version "1.6.0_24"
4OpenJDK Runtime Environment (IcedTea6 1.7.9) (rhel-1.36.b17.el6_0-x86_64)
5OpenJDK 64-Bit Server VM (build 14.0-b16, mixed mode)
Done!
