Along those same lines & somewhat related; if I do java -version or java
--version on one machine, I get:
:~/javascore$ java -version
bash: java: command not found
On all others I get a proper response.
So, I used:
sudo update-java-alternatives -a
(-a for auto) and now it shows up properly:
$ java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode, sharing)
$ sudo update-alternatives --config java
There are 2 alternatives which provide `java'.
*+ 2 /usr/lib/jvm/java-6-sun/jre/bin/java
Press enter to keep the default[*], or type selection number: 2
Using `/usr/lib/jvm/java-6-sun/jre/bin/java' to provide `java'.
Interesting part is that I just installed Sun JRE 1.6.0.01 but it's not
showing up in alternatives. However if I use an application - OpenOffice
for instance and from OOo do Tools|Options|OpenOffice.org|Java, both JRE
version 1.6.0 and 188.8.131.52 show up.
So I guess I'm in the same cat as the OP, and find the 'which version'
confusing as well. Anyone have a link that helps explain how all of this
works on Ubuntu/Debian in basic terms?
