If you decide to upgrade your Java RRD MA installation, it might be a better
idea to use a fresh version from the CVS (I'm afraid we haven't tested
PerfsonarUI against the snapshot from 14 Feb either, because of lack of access
to a running service with this specific version). Note, it might still work,
but not for sure.

The UI v0.05 has been tested against and supports the following well known
schemas/service versions/implementations, which were accessible during the
release preparation:

- Protocol: NMWG(v2) 1 (Pre Namespace versioning), Implementation: Java,
Version: 0.1 (EGEE tag)

- Protocol: NMWG(v2) 2 (With Namespace versioning), Implementation: Python,
Version: 0.1-19

- Protocol: NMWG(v2) 2 (With Namespace versioning), Implementation: Java,
Version: CVS snapshot from 2006-03-04 14:09 (EET)

Nina might have a look on what's causing the incompatibility issue with your
previously installed version, but it would be also really nice if you could
upgrade it.

Well, I would say that the schema/namespace should change much less frequently
than what is the case up to now. Imagine changing some protocol every other
day and than developing applications, which can speak tens or hundreds of
protocol jargons... Let's try to keep this number below 5 or 10 ;-)

Kind regards,
