Metacat

Replacing MetaCatUtil.debugMessage or MetaCatUtil.logMetacat call with logMetacat (private Logger object) call

Change the method to get access document docid and revision.

add code to make sure subject, relationship and object is not null.

Change the code to get docid.

This class will write triple to db.

Using triple rather than query to get relation.

Add some debugMessage.

Change debugMessage prototype.

Code to handle text node was splited.

Merge DBConnection branch to head.

made it so we can now use multiple accessfilestypes and packagdfiletypes in the metacat.properties file. Also fixed a bug introduced when the 'http://' was removed from behind the server name in the loaddtd.sql script and the knb.xml file

- when the Access file goes first before the Package file (eml-dataset-2.0)
relations are not available in xml_relation, thus updated the code
to check and run ACL also after the Package file is saved.
- cut out the rev# from subject and object in xml_relation as needed by ACL...

Added fix to DocumentImpl that showed problems when the DocumentImpl(conn)
constructor was called. Now there is a new constructor:
DocumentImpl(Connection, String, boolean)
where the boolean value is used to determine if the nodeset should be
read a t the time the cosntructor is called. if false, then...

Simplified ReplicationHandler:
It is run now in the same thread started from DBSAXHandler;
thus the same connection opened in that thread is used,
i.e. no need for new connection and no complains as "Connection is closed" in ReplicationHandler;
"Connection is closed" error happens when in the current thread there are try to use connection opened in another thread,...

Modifications that change the package handling behavior of metacat. Package
membership is now determined by an identifier being used as either the subject
or object in a triple. One can not request arbitrary returndocs -- only
those types that have package information embedded can be "returndoctype"...

fixed some problems with database connections getting a time out error. Also updated some catch statements

fixed bug that was accidentally introduced when the change from metacatURL to URL was done.

added precise location information (class.method) to each catch statement so that errors are more easily traced.

fixed introduced problem with preparedStatements

Added license terms to source code files, and cleaned up some javadoc
documentation in a few places.

closed all preparedStatement variables

removed dependence on MetacatURL for URL handling. Added more flexible support for identifiers in the subject and object fields. They can now be just a docid, an http url or a metacat url.

- appling acl through access files only
- clearing around update/delete of access files - to delete the related records from both xml_access and xml_relation tables
- included check for user permissions for setting acl on the resources in the access file
- moved RelationHandler.deleteRelations(docid) down in RelationHandler obj just before the write of the new relations

updating a package file now updates the relations that are created from it. Also, if you delete a package file, it will delete the relations associated with it.

changed connection handling in the constructor

Modified stylesheets and server code to use a single "read" action instead
of the earlier "getdocument" and "getrelateddocument" actions. In the
process, developed and started to utilize a new suite of URL "protocol
handlers" that are in the package "edu.ucsb.nceas.protocols" and handle...
