Hi Suntish

Read https://help.ubuntu.com/community/Java

Thats should point you in the right direction.

The reason for your problem is that by default GCJ is
installed which is essentially a Java replacement. You
need to install sun-java6-jdk through Synaptic. You
can put other versions of Java on your machine but
they won't be the default Java version, so you have to
mess with a thing called Alternatives.

All of the details are in the above link.
