When you added the JDK 6 installation, most likely the installer altered
your system path to place that installation first on the path. Try
creating a new Jenkins job containing a shell script job step with the
command "which java". That will tell you where the OS is looking when
you call java without giving a full path.

But I used the GUI option for Jenkins to install JDK from java.sun.com
and never specified a fullpath location for JDK in the first place
when I added a JDK7 installation.
Later I added and removed a JDK 6 installation. All was done via GUI.
So I am at a loss as to what went wrong and how I can recover from it.
Thanks Eric for your help.

I think you have picked up on the solution there. Either always
use the full path to the desired Java installation, or alter your
path so that 'which java' returns the correct path.

I do not see a Java Version list box in my job config page in UI.
I have expanded varios Advanced section in the page but still do
not see Java Version list. I am using Jenkins version 1.531.
The only Java Version available in Jenkins global config is JDK 7.
One odd difference I notice in the logs for a successful build
vs. failed build is that the failed build uses java command
without fully qualified path while successful build uses fully
qualified path to corect jdk.

This seems significant.
Many thanks for your help Ullrich!

Hi Guys,
Initially all was well and my Jenkins config.xml was
configured for just JDK7.
I then added a JDK6 installation to Jenkins config and did a
new build manually.
The build failed and on examination I realized my project
requires JDK7 to build.
So I edited my Jenkins config to delete the JDK6
installation I had added prior to previous build that had
failed.
Now only the JDK7 installation was left in Jenkins config.
I did another build but now I see that it is still trying to
build with JDK6 only instead of the JDK6 installation I had
added from Oracle it is now using the JDK 6 that is part of
my Ubuntu setup.
What am I doing wrong and how can I make Jenkins only use
the JDK7 that I have configured?
