h1. Update Java

* Download the latest version of the _Java Development Kit_ (JDK) as a self-extracting binary file from [http://java.sun.com/javase/downloads/].

* Make it executable and install it into _/usr/java/jdk-XXX_.

<pre>

  # chmod u+x jdk-XXX.bin

  # ./jdk-XXX.bin

</pre>

* Move it to the the same folder with all other Java versions:

<pre>

  # mv /usr/java/jdk-XXX /usr/lib/jvm

</pre>

* Install the new version within the _alternatives_ system:

<pre>

  # update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk-XXX/jre/bin/java 300

</pre>

* Select the new version as the default using:

<pre>

  # alternatives --config java

</pre>

* Check the version of the default java installation:

<pre>

  # java -version

</pre>
