Re: Problem with XML RPC

[Kay-Uwe Kasemir <kasemirk@ornl.gov>]

Hi:

There should be a file similar to
 /tmp/archserver.log
that logs the request which the network data server saw.

If you exercise that same request with ArchiveDataClient.pl,
you might see a better error message.

Right now I don't know what the problem is.
The archive data files could be damaged,
but that shouldn't be the case with the
demo data.

Are the data files accessible?
Maybe you just made the index file accessible,
but not the data files?
