Mr. Roland:
This is what I get. How do I now get Oracle JDK to be identified
anand_vihar@Latitude-E5540:~$ sudo update-alternatives --config java
[sudo] password for anand_vihar: 
There is only one alternative in link group java (providing /usr/bin/java): /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java
Nothing to configure.

Thanks

 Hi,

If you are using Ubuntu then add these lines to /etc/environment 
JAVA_HOME=<actual path to jdk>
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:$JAVA_HOME/bin"

Please put the actual path to JDK in the first line.

Regards,
Ravindra

 Anand,
Sorry about that, I was assuming Redhat/Centos.
For Ubuntu, try sudo update-alternatives --config java.

Dear Mr.Roland:
The alternatives command errors out. I have the extracted version of the Oracle JDK7. However
I am ignorant regarding its installation on Ubuntu. Can you point me to installation material
so that I can look up and try.
Thanks

 Anand,  My guess is that your alternatives setup isn’t complete.  At a prompt, as su,
run the command ‘alternatives - - config java’. Make sure that the oracle version is listed
and is marked as the active one.   If it is not, go through the steps to make sure it is.
