XMLDB psuedo Proptocol in cocoon2.0.4 failure in registering driver DatabaseImpl.

[Subrahmanya, Noida]

Hi,         I am setting up an application which reads from an XMLdatabase using the XMLDB API's on cocoon 2.0.4 . This was running fine on cocoon 2.0.3. The problem i am having is when an XMLResource is being read from the XML database. It throws an XMLDBException with the reason being could not read XMLResource.      I have seen that this occurs due to the DatabaseImpl not beeing registered to DatabaseManager. In 2.0.3 It registers the database driver in method public void connect() of XMLDBSource. Now in 2.0.4 it has been moved to method public void configure(Configuration conf) of XMLDBSourceFactory which is beeing i think not called internally by cocoon API. So failure in getting instance of DatabaseImpl from DatabaseManager. I am getting following Exception. Could u please correct me if i am wrong.? What would be the solution for that?   ERROR   (2002-12-12) 13:07.02:361   [core.manager] (/cocoon/demodb/) HttpProcessor[8080][4]/sitemap_xmap: Sitemap org.apache.cocoon.ProcessingException: Could
