update-alternatives : update java path

Question

I want to update the java path.After running the command

 sudo update-alternatives --config java

I get following :

        Selection    Path                                      Priority   Status
        ------------------------------------------------------------
          0            /usr/lib/jvm/java-6-openjdk/jre/bin/java   1         auto mode
          1            /usr/lib/jvm/java-6-openjdk/jre/bin/java   1         manual mode
        * 2            /usr/lib/jvm/jdk1.7.0_25/bin/java          1         manual mode

Now I want to update the path for jdk1.7.0_25.

what should i do?

Answer 1

According to the man page there is no parameter for update-alternatives to change an entry. So you would have to remove your entry 2 with --remove and --install it again. Then you might have to --config the command again to point to the correct directory.

Alternatively, you can manually change the entry in /var/lib/dpkg/alternatives/java directly.
