Metacat

added extra timing information to the main() driver method.

fix the small bug with output like:
Fatal processing error

<success>
<docid>null</docid>
</success>
on hadleInsertOrUpdateAction()

writeDocID() not needed any more
throw SAXException from everywhere

on character(cbuf, start, len) included:
if currentNode.getTagName().equals("title")
currentDocument.setTitle(cbuf)
instead of using:
currentDocument.setTitleFromChildElement() in endDocument() call

change Assession# generation to use the same db connection

Updated the download data function. the download data function now pulls a document from the database, zips it up and sends the zip stream to the client. It also zips up any related files. a relation parameter is used to pass related files to the servlet. If only one document should be zipped and sent, a single docid in the param hashtable is sufficient.

changes related to decrease the time of INSERT of document.
With these changes I inserted 200KB file for 3 minutes, 50KB for 50sec.
This is mainly simplifing the DBSAXNode class and
using batching feature of Oracle JDBC driver.

This allows for the easy handling of metacat:// urls. The documentation in the source code explains the specification for the url in detail.

Added functionality for package specifications. metacatservlet now contains a new action called getrelateddocument that handles retrieving related documents using the metacatURL specification (metacatURL.java). DBQuery contains new code in runQuery that embeds relation tags in the returned hashtable describing the documents related to each docid. querySpecification contains a new method which prints the sql that does the relation query.

store generated Access# in meta_file_id tag if there are any
