[Solved] How to specify which version of Java to use?

I have OpenJDK 7 as my default, but I also am trying to use Oracle's Java 7 for a specific program. I have installed jdk7-compat as suggested by the arch wiki, but I am unsure how to use it specifically.   
   
java -version outputs:

OpenJDK Runtime Environment (IcedTea 2.5.0) (Arch Linux build 7.u60_2.5.0-2-x86_64)
OpenJDK 64-Bit Server VM (build 24.60-b09, mixed mode)

so OpenJDK is  still the default, which is good. At the same time, how do I use Oracle's Java for a specific program?

You have to create a bash script to execute that program, where you define your Java variables. For example, let's supposed your oracle Java is installed at /opt/java_1.6.14/ folder

#!/bin/bash
export JAVA_HOME=/opt/java_1.6.14/
export PATH=/opt/java_1.6.14/bin:$PATH
<your command>

@TheGuyWithTheFace: FYI I've just pushed a set of OpenJDK7 packages to [testing] that does not declare conflict on java-{environment,runtime}. OpenJDK8 will then follow. You might want to try these.
