Metacat

fix around one way replication:
when server A sends document to the servers in its list of replication servers with replicate=1 in xml_replication table,
the server B received the document does NOT need the opposite check on its end.

fixed error:
writing on the replication server required the whole acc# (including the rev#)

Fixed bug in metacat where an Exception was thrown when a search returned
an empty resultset. Now we avoid the function call that threw the exeption.

Added support for multiple user interfaces by enabling style sheet
transformations to be configured from within metacat rather than

a "style set", which is mapped to an xml configuration file that...

small fix to enable resolving external entities included in the DTD;
external entities are now resolved successfully by DBEntityResolver using the specified system ids
and thus there no need of registering the relative system ids,
This is because EntityResolver uses its internal implementation to map the relative system ids to the...

Removed the requirement that the relationship for ACL associations be

"describes access control rules for". This doesn't affect the ACL
processing because it is based on the ACL document type, not the...

changes to store namespace prefixes separately from the local names of nodes (elements and attributes)
in xml_nodes.nodeprefix column

Revised build.xml and metacat.properties to make it easier to
install alternative stylesheets for metacat. In the process,
replaced the deprecated copydir and copyfile commands in build.xml
with appropriate "copy" commands.

added support for Namespaces.
Metacat now can store and retrieve XML documents with Namespaces.
Namespace is stored as separate record in xml_nodes table with type "NAMESPACE"
where nodename is the prefix and nodedata is the uri of the namespace.

fixed an error of NullPointerException
