Java does not update, you just install a newer version.

You can get update 2 here:

You want the non-rpm version. It is a self installing binary but you
must make it executable using "chmod +x ???.bin"

Java is installed in the "/usr/lib/jvm" directory on Ubuntu but you can
put in in /opt if you want. Then just change the symbolic link to the
java executable in "/usr/bin".

You could install in "/opt" to if you want, as long as you change the
symbolic link accordingly.

Install it using sudo.

On second thought, you could just add a new symbolic link to "java" in
"/usr/local/bin" and leave the one in /usr/bin alone. "/usr/local/bin"
is before "/usr/bin" in the environment search.

Always get the latest Java Runtime Environment here:
http://java.sun.com/javase/downloads/index.jsp

You should get: Java Runtime Environment (JRE) 6 Update 2 unless you
are developing actual Java code in which case get the JDK 6 Update 2.

Be sure to download/copy the installation instructions, Readme, and
Release Notes before clicking on the donwload link.

On the download webpage, it is necessary to check the Accept button
for the license for anything to happen, otherwise nothing happens.

Well, I tried the update but it didnth help. Im still getting a blank
screen.
