When I do:

sudo update-alternatives --config java

I get:
Selection Path Priority Status
------------------------------------------------------------
0 /usr/lib/jvm/java-6-openjdk-i386/jre/bin/java 1061 auto mode
1 /usr/lib/jvm/java-6-openjdk-i386/jre/bin/java 1061 manual mode
* 2 /usr/lib/jvm/java-7-openjdk-i386/jre/bin/java 1051 manual mode

I am new to java. From my reading, I understand that this means version 6 is the default?

How do I set version 7 as default and make it auto mode?

I tried what I found here:

http://askubuntu.com/questions/308663/how-to-set-the-default-java-version

Adjusting for my path
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/java-7-openjdk-i386/jre/bin/java" 1

And I get:
update-alternatives: warning: forcing reinstallation of alternative /usr/lib/jvm/java-7-openjdk-i386/jre/bin/java because link group java is broken

Is this something to sorry about?
It looks like the default is now changed but auto mode is still set for 6
bruce@debian1:/$ sudo update-alternatives --config javaThere are 2 choices for the alternative java (providing /usr/bin/java).

Selection Path Priority Status

0 /usr/lib/jvm/java-6-openjdk-i386/jre/bin/java 1061 auto mode

* 2 /usr/lib/jvm/java-7-openjdk-i386/jre/bin/java 1 manual mode



How do I change that?

 

Try this (with sudo if needed):
update-java-alternatives -l
update-java-alternatives -s ..name

 

literally "..name"?

I might just leave it. Seems the jar file that I needed Java 7 is running fine.

That's the '...name' of the java package for the default from the list option update-java-alternatives -l

 

What I figured but wanted to be sure. Obviously Linux is not my primary OS that I use.
