I found that open jdk was also installed on that machine .
Removed that as well .. also installed the fresh sun jdk(same 1.6.0.. as after oracle they ask for registration to install :( ) .. and got the same error.
Error trace from geronimo.log is as follows:

Could you check that what is the actual JRE version in the log file var/log/geronimo.log ?
There should something like :
INFO  [Log4jService]   JVM in use        = ****

From the exception message, it seems that it is caused by JRE loads an old jaxb 2.0 api. 
One solution is to upgrade the JRE on that machine, another solution is to download the jaxb 2.1 api package and place it in the endorsed directory, which is suggested by the exception message.

I am also successful with jdk 1..6.0_13 on my personal machine.
Not able to figure out the problem with this machine.
Between checking with my jdk on this machine.

I can run g 2.2 on my ubuntu with sun jdk 1.6.0_20, can you have a try with that?
