How did you install it? What did you install?

Anyway:

http://wiki.debian.org/Java/Sun
Running the following should just work:
Code:
apt-get install sun-java6-jdk

LawlessBaron 07-07-2011 01:05 PM
when i try to install i get this

Code:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package sun-java6-jdk is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package sun-java6-jdk has no installation candidate

I guess, you are missing the 'non-free' entry in /etc/apt/sources.list

sun-java6-jdk is available http://packages.debian.org/squeeze/sun-java6-jdk
http://packages.debian.org/search?ke...=sun-java6-jdk

.. Can also be added in Synaptic > Settings > Archives : non-free

i only have ssh access how can i add it to the resources list ?

LawlessBaron 07-07-2011 01:50 PM
Ok i added the link to sources.list after that should i do
Code:
apt-get update
and if so should
Code:
java -version
work for me ?

knudfl 07-07-2011 01:59 PM
After # apt-get install sun-java6-jdk :

You can see if 'java -version' replies "java version "1.6.0_2x" etc.

If any doubt :
# update-alternatives --config java
... and then select the "sun java".

.

apt-get install sun-java6-jdk

anyone any idea?

LawlessBaron 07-07-2011 03:11 PM
can someone help me resolve this issue please ?

knudfl 07-08-2011 04:47 PM
Probably : # apt-get -f install && apt-get update
.. to be able to install packages again.

Next : ls -l /etc/alternatives/ | grep opt
And then remove the link / links pointing to the alien java* in /opt/.


Now it should be possible to install : # apt-get install sun-java6-jdk
Hopefully the correct links will be made in /etc/alternatives,
making it possible for # 'update-alternatives --config java'
to select "/ust/lib/jvm/java-6-sun/jre/bin/java".
( Or see, that it has been set already by the install of sun-java6-jdk.)
(( Can be checked with 'java -version' too.))
