Just notice

/etc/alternatives/javaws -> /usr/lib/jvm/java-6-sun/jre/bin/javaws


change to 7 works.



If you're going to use Oracle Java, I would suggest this:

http://www.webupd8.org/2012/06/how-to-install-oracle-java-7-in-debian.html

    I've been using this for several years and it works flawlessly. The
major problem people have is setting the alternatives correctly. This
method does just that, in spades. There is a java version 8 as well,
but I am staying with version 7 a bit longer. You will enjoy this!
Plus, you get version updates automagically. It really doesn't get
any better. I just tried your link, and it fired up the first time.


Note that the Debian package java-package allows to create your own Oracle
Java debbals.


Will it set all the alternatives? That can be an major issue. Ric


The created debballs set up alternatives apparently: on my box:

mybox$ update-alternatives --display javaws

give

javaws - auto mode

Right, but I meant all the other java alternatives. There are a bunch of
them:

ControlPanel, appletviewer, extcheck, idlj, jar, jarsigner, java,
java-vm, javac, javadoc, javafxpackager, javah, javap, javaws, jcmd,
jconsole, jdb, jexec, jhat, jinfo, jmc, jos, jrunscript, jsadebugd,
jstat, jstatd, jvisualvm, keytool, the mozilla plugin which links to
libnpip2.so, native2ascii, orbd, pack200, policytool, rmic, rmid,
rmiregistry, schemagan, serialver, servertool, wsgen, wsimport, xjc.

You made me look. :0  I didn't know half of these existed until I used
that installer. It's just a script which will directly install Oracle
Java FROM Oracle. Then after it sets everything right. I love it, as I
am lazy and Andrew does a good job at it. Just a FYI, Ric


Fortunately we have /usr/sbin/update-java-alternatives (provided by the
java-common package) to update them all in one go, should you need to.
I know in the past it didn't set half as many alternatives as this PPA manages to do.
Just checked that man page and the alternatives selections are set in /usr/lib/jvm/.java-7-oracle.jinfo
So, whatever is in that script sets the alternatives up. No clue what a stock Debian or installed from tarball-file Oracle Java would provide.
