Just installing new Java flavours does not change the default Java pointed to by /usr/bin/java. You must explicitly set this:

• Open a Terminal window

• Run sudo update-java-alternatives -l to see the current configuration and possibilities.

• Run sudo update-java-alternatives -s XXXX to set the XXX java version as default. For Sun Java 6 this would be sudo update-java-alternatives -s java-6-sun

• Run java -version to ensure that the correct version is being called.
