How to connect Tomcat 4.1 to MS SQL2000?

<Context path="/boa"
         reloadable="true" >

<Realm className="org.apache.catalina.realm.JDBCRealm" debug="99"
userTable="users" userNameCol="user_name" userCredCol="USER_PASS" userRoleTable="user_roles"
roleNameCol="ROLE_NAME" />

Above is the tag I have in my server.xml to define the site and the Realm to connect to MS SQL2000.  I have put the driver jar file into /server/lib folder of Tomcat but I keep getting the error below, any reason for it? I have made sure I use the JDBCRealm that comes with Tomcat.

Can you connect to the database using a JSP? This would check that the database permissions are correctly set for the user that you are using. and that the password is correct

It is also possible that database is not listening at port 1433 for incoming connection ( will have if somebody has dorked around the SQL server settings)..
What data types are you using? Are you using blobs anywhere?
