Metacat

When I went to epsilon and dev.nceas.ucsb.edu/tao/replControl.html (I tried
both http and https )

It can update server list. But when I set up server and wanted force
replication, it didn't work in both sites: can't bring all updated documents
from remote hosts to this server ( web site said it should do it). In epsilon
web site I got an error: error in ReplicationHandler.update: The root element
is required in a well-formed document, In dev, I got Error in
MetacatReplication.handleGetOrPost: null.
