Java changing the default JRE

If you installed a new version of the JDK or JRE you may need to run the following commands to change the default JRE. Use java -version or the command below to determine which JRE the system is currently using.

1. Run the following command to determine the default jre being used by the system.
• /usr/sbin/alternatives --config java
2. If the JRE used is not the one from the JDK execute the following command so that the default JRE is the one that belongs to the JDK.
   
• /usr/sbin/alternatives --install /usr/bin/java java /usr/java/jdk1.6.0_16/bin/java 2
