Hello i am getting warnings after i have installed java on kubuntu 11.10. The java programs run but i always get 4 warnings:

$ java
Warning: no leading - on line 1 of `/usr/lib/jvm/java-6-sun-1.6.0.26/jre/lib/amd64/jvm.cfg'
Warning: missing VM type on line 1 of `/usr/lib/jvm/java-6-sun-1.6.0.26/jre/lib/amd64/jvm.cfg'
Warning: no leading - on line 1 of `/usr/lib/jvm/java-6-sun-1.6.0.26/jre/lib/amd64/jvm.cfg'
Warning: missing VM type on line 1 of `/usr/lib/jvm/java-6-sun-1.6.0.26/jre/lib/amd64/jvm.cfg'

What am i missing? Thanks in advance!

Here is the file content /usr/lib/jvm/java-6-sun-1.6.0.26/jre/lib/amd64/jvm.cfg :

Please attach the contents of the /usr/lib/jvm/java-6-sun-1.6.0.26/jre/lib/amd64/jvm.cfg file to your question. –  daveb Mar 31 '12 at 13:14

Have you gone through the following procedures?

Open terminal and run the following commands

Add partner repository using the following command

sudo add-apt-repository “deb http://archive.canonical.com/ lucid partner”

Update the source list

sudo apt-get update

Now install sun java packages using the following commands

sudo apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts

The above command will download all the required packages and begins the installation, you’ll get a screen that contains the Sun Operating System Distributor License for Java and hit Enter to continue.

You’ll see a dialog that asks you if you agree with the DLJ license terms. Select Yes, and hit Enter; the JRE will finish installing.

Testing Java Runtime Environment

You’ll want to confirm that your system is configured properly for Sun’s JRE. This is a two-step process.

First, check that the JRE is properly installed by running the following command from a terminal.

The problem was a missing # in the first line before the /usr/lib/jvm/java-6-sun in jvm.cfg file. I have not figured out why it was missing. Now its working fine without any warnings. Thanks.
