I need to be using Openjdk 6 but cannot figure out how remove Openjdk 7. I used the apt-get purge command and it seems to be successful but even after installing Openjdk 6,

java -version

always returns

java version "1.7.0_25"
OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1ubuntu0.13.04.2)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)

What can I do to fix this?

You can install OpenJDK 6 using sudo apt-get install openjdk-6-jre and set it as default using sudo update-alternatives --config java and then selecting the OpenJDK 6 one.
