Hi,
I am building a project in struts.I am using Sql Server 2000 database for backend.
I am getting an exception of"No Suitable Driver" when i am trying to connect to database.
I have successfully build the User DSN say "attendance" using ODBC.
I have used following driver to connect to database:

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
DriverManager.getConnection("jdbc:odbc:attendance","sa","");

Please tell me where i am going wrong.
Please guide me to connect to database.

ThankYou.

Hi,

Did you include the sqljdbc jar file in libraries ? Kindly check for sqljdbc.jar file in your project's lib folder, if its not there

you can get it from

http://www.microsoft.com/downloads/details.aspx?familyid=e22bc83b-32ff-4474-a44a-22b6ae2c4e17&displaylang=en


Cheers!!!

Hi Ujwal thanks for your help.
I have included sqljdbc.jar in the path but that doesn't work.
I change the code to:

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
con=DriverManager.getConnection("jdbc:sqlserver://localhost;databaseName=attendance","sa","");

Now it is giving an error:
Unable to Initialize Data Source (com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host has failed. java.net.ConnectException: Connection refused: connect)

Please help.

Is there any other way to connect to SQL Server 2000?

See whether "attendance" database/DSN exist or not

A DSN should not be required. Why do you want to use ODBC?

Make sure your database instance is configured to accept connections over TCP/IP (for SQL Server 2000 this should be the default case) and make sure it is configured to support SQL Server authentication (by default this is not the case).

I am not using ODBC

Ah - re-read your second post. I just noticed you were using ODBC in your initial question. Sorry.

Your code looks OK. Have you checked the configuration of your server for the things I suggested?

Hi Paul,
What about the port number and chances of its being block by firewall ?

I would be very surprised if the port number had been changed and in that instance I'd expect the connection to time out, rather than being refused. The exception message would also be different if a Firewall prevented it - the message would be something like "software caused connection abort". Given SQL Server 2000 is not configured to accept connections using SQL Server authentication by default I would think my second suggestion is the more likely one.

Hi,
The error of TCP/IP has been removed.Now I am getting an error of:
No Suitable Driver for jdbc:sqlserver://localhost;databaseName=attendance","sa",""

Which type of Driver it is talking about.Can you explain..I have included sqljdbc.jar in the libraries but still i am getting the above error.
Can you tell me about driver.
Thanks

You get that error for one of two reasons:
  • There is no JDBC driver in your classpath
  • The JDBC url you are using is not one supported by any of the drivers in your classpath


  • Reading the driver documentation the syntax for the urls is:

    so your URL looks OK, which means you must not have the driver jar files in your classpath.

    Check that is not stopping the connection. Also worth checking what patch level SQL Server is at, some (very early) versions had issues in their tcp/ip DLLs.
