Hi,
I am trying to connect to SQL server Express DB installed on localbox from my java program. I am using jtds driver and the sample code is below.




When I try to run the program, I get an error saying "java.sql.SQLException: Network error IOException: Connection refused: connect"

If I use



I get an error "java.sql.SQLException: Server localhost has no instance named SQLEXPRESS."

I have the driver jar in class path and my VM args are "-Djava.library.path=C:\jtds-1.2.5-dist\x64\SSO" pointing to the NTLM dll.
I am able to connect to the DB from the MS SQL Server Management Studio.

Can somebody help me to solve this?

The first message invariably means that you don't have a server listening at the specified port. So do you have your database server running on the same computer where your application is running? (That's what "localhost" means.) And is it listening at port 1433? I'm not sure about the Express version, but by default SQL Server is configured to not listen for TCP/IP connections. It expects to be contacted by some proprietary Windows method which isn't supported in Java. So check that configuration and turn on the TCP/IP option if it's not already on.
