Exception Error when I try to initialize hudson.war

I have installed hudson on Ubuntu server and then run java -jar hudson.war, giving me this exception error message:

Do you know what I am missing? any suggestions would be very appreciated.

You probably run the wrong java. Check if you use sun's oracle's java.

See here for other people that had this problem: http://ubuntuforums.org/showthread.php?t=1434376

same comment, you probably have the wrong java version.
You can specify the correct path to the java binary in /etc/default/hudson.
If you use jenkins then edit /etc/default/jenkins instead.

# /etc/default/{hudson,jenkins}
JAVA_HOME=/path/to/jdk_1.6
JAVA=$JAVA_HOME/bin/java

Encountered a similar issue due to no more space in /tmp (root partition).
