Installing Sun Java 6 JDK

In the past, SyMBA was tested on both Sun Java 5 and Java 6. Currently, we recommend that you use Java 6.

Install Sun J2SE Development Kit 6.0 (JDK 6.0)

If you are using earlier versions of Ubuntu than Natty Narwhal, you can install Sun Java 6 simply with an apt-get command:

  sudo apt-get install sun-java6-jdk

If you are running a more recent version of Ubuntu such as Natty, you will find the above command fails unless you have the partner repositories enabled in your /etc/apt/sources.list. You open this file (you must have root access to do so), and un-comment the following line by removing the '#':

  deb natty partner

After you have saved the above change, then you may run the apt-get install command mentioned above after you have propagated the update to the system:

  sudo apt-get update
  sudo apt-get install sun-java6-jdk

and then optionally set the default version in your system with

  sudo update-java-alternatives

Alternatively, you can download the latest Java from Sun directly .

Check Your Installation

Make sure that the JAVA_HOME environment variable is pointing to the directory where you installed the JDK.

If using the "apt-get install" method for Ubuntu described above combined with the update-java-alternatives command, you should already have this variable set.
