Hi all,
i am trying to install Bluej on ubuntu 12.04. In the website i found out that first at all i have to install the sun-java6-jdk but
after my input
Code:
sudo apt-get install sun-java6-jdk
this is the output

Code:
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package sun-java6-jdk is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'sun-java6-jdk' has no installation candidate
how can i solve the problem?
thank you
