Separate thread used for writing into xml_index table.
This cut the time of the response on insert almost in half.
The tread is started afterwards
(on end of document parsing and inserting into xml_nodes) from
DBSAXHandler and uses new(separate) db connection....

This class syncronously indexes any package file that is loaded into the database.r

Added backtrack functionality. Backtracking works by passing a returndoc parameter. There can be more than one. If a document that is hit by a query is not of type returndoc then it searches the database for a related file of type returndoc. If one is found it is displayed, if no relation is found, the original is displayed....

included new method getPoolSize()

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.
