505 10/27/2000 07:07 PM Matt Jones

Began work on new UI for the KNB web site. It will be the main query
interface from the KNB website.

504 10/26/2000 02:38 PM Matt Jones

Fixed the LDAP authentication adapter (AuthLdap.java) so that it now looks up
the distinguished name for a user before attempting to do authentication.
This is because the user's distinguished name can sometimes be based on
their uid attribute, but sometimes be based on their cn (common name)...

503 10/24/2000 01:03 PM bojilova

merge AUTH_LDAP to the main branch

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....

466 09/26/2000 03:07 PM berkley

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

465 09/26/2000 03:06 PM berkley

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....

currentDocument.setTitle(cbuf)
instead of using:
currentDocument.setTitleFromChildElement() in endDocument() call

459 09/20/2000 01:15 PM bojilova

change Assession# generation to use the same db connection

458 09/20/2000 10:58 AM berkley

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.

457 09/15/2000 05:40 PM bojilova

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.

454 09/15/2000 12:53 PM berkley

453 09/15/2000 12:52 PM berkley

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.
