perfsonar development work

[Szymon Trocha <>]

Hi Vedrin,

Thanks for your helpful tests. Hopefully the new functionalities like 
Roman's Echo and my most wanted result codes could be incorporated into 
psUI in future significantly helping us to detect the roots of problems.

For those I know about:
CARNET - Igor was on holidays, CARNET is currently changing the person 
working on JRA1
GEANT - in progress - Loukik is fighting with installations
I2 - in progress - Jeff is fighting with installations
UNINETT - reported problems with Java version

Here you can see error codes helpful. eXist crashed for both services 
but only one reports meaningful message.
Both should be running now.
