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

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. -
