Metacat

changed the getDate method to getDateTime and changed the return
string in the postgresql implementation to "now()" from now()::date

change the call from getDateString() to getDateFunction()

change the method name getDateString() to getDateFunction()
return "now()::date" in the DBPostgresql implementation of that method

The Postgres implementation of the dbadapter package, still needs testing and
the getDate... method just returns the db function to return the date; to retreive the
current time is a second function so we may want to add a second method to return the
current time.

changed the db sequence name used for the accession# uniqueid
to xml_documents_id_seq.
All db sequences now are named of form <table_name>_id_seq

added new property for the dbadapter class as:
dbAdapter=edu.ucsb.nceas.dbadapter.DBOracle
the installation procedure should change it to the appropriate class

- changed to use the DBAdapter uniform interface for all apperance of "sysdate"
and uniqueid generation from sequence
MetaCatUtil:
- reads from metacat.properties the dbadapter class implemented the interface
and creates an instance of that class (in static public variable named dbAdapter) for use....

the abstract DBAdapter class and its Oracle implementation
for the new dbadapter package

Fixed bug in metacat where return doctypes were not being properly
back traced. Changed DBQuery.findDocuments() so that it no longer
takes a returndoc array, but instead retrieves the returndoc array
fromthe QUERYSpecification. The QuerySpecification was augmented...

Added ability to process multiple "returndoc" elements in
a pathquery document. Now, any query hit will be back traced to an
associated package if that package is listed in one of the
"returndoctype" elements.
