Metacat

make sure querygroup is not null before trying to print it.

Get the latest revision from metacat when a modify call docid does not have a revision number.

Send appropriate message when trying to update a docid that was previously deleted.

Reformat file. No code change.

do a quick retry if building path index fails with a SQL error

Make sure buildIndex throws an exception if it has a sqlexception. That way the indexing object will be added to the indexing queue and reprocessed.

Pass the doc xml as a string to docImpl.write and writeRepication. This is so a reader can be create for the parsing and for the write to disk. Also created a db access class for xml query result deletion.

make constants final

Fix the bug of http://bugzilla.ecoinformatics.org/show_bug.cgi?id=4645. handleGetRevisionAndDocTypeAction will search both xml_documents and xml_revisions table.
It also changed some constrain in AccessionNumber when user update a document, of which all previous versions are in xml_revisions table.
