OpenFire and MS SQL2008 Database -Error

I have been trying to integrate with Ms sql2008 Server with Openfire Server , But i get the following error when i try to do it.

"A connection to the database could not be made. View the error message by opening the “\logs\error.log” log file, then go back to fix the problem. "

The Log file is attached.

I have successfully opened the openfire_sqlserver.sql file under the SQL 2008, and all the tables are created. and the Data base URL is

jdbc:jtds:sqlserver://UDHOWLIT007\SQLEXPRESS/[database-name];appName=jive
