getting I/O Error: DB server closed connection

[ivin jacob]

I am getting the Following exception while trying to connect to the SQLSErver DB

I am using jtds-1.2.2.jar File.

I am using Windows Authentication and i am able to connect though the SQL SErver Client Application

I complete stack trace is pasted below

org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (I/O Error: DB server closed connection.)
at org.apache.commons.dbcp.BasicDataSource.createDataSource(BasicDataSource.java:1225)
at org.apache.commons.dbcp.BasicDataSource.getConnection(BasicDataSource.java:880)
at sgstool.dbConnection.DBConnector.getSimpleConnection(DBConnector.java:43)

Can anybody tell me why this is occuring and tell me how this can be tackled

Regards,

Ivin
