Error connecting to SQL Server 2000

[Anas Nashroel]

Hi,
I have a problem with using SQL Server 2000 with my application.
Here's the data access code:

   
package solmit.sisdik.model;
 

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
 
import org.apache.log4j.Logger;
 
public class DataAccess {

 

//this is sql server 2000 connection configuration
private String dbURL = "jdbc:microsoft:sqlserver://localhost:1433;Databasename=idnsdb;User=idns;Password=genetix";


protected Connection con = null;

static Logger log = Logger.getLogger(DataAccess.class.getName());

public DataAccess() {

try {
//Class.forName("com.mysql.jdbc.Driver").newInstance();
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
}  catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

try {
log.debug("trying to get db connection");

con = DriverManager.getConnection(dbURL);
log.debug("connecting db succeeded");
} catch(SQLException sqle) {
log.debug("connecting db failed");
sqle.printStackTrace();
}
}

public Connection getConnection() { 
return con;
}

public void releaseConnection() {
try {
con.close();
} catch(SQLException sqle) {
sqle.printStackTrace();
}
}

public void connect() {

}

public void terminateConnection() {}
}
 

and here's the error messages:

I have dropped jdbc driver (msbase.jar, mssqlserver.jar, msutil.jar) to the webapp lib folder
Are there any issues regarding connection to SQLServer 2000 through java application ??

Thanks in advance,
Regards,

My spec:
Windows XP Professional
Tomcat 5.5
JRE 1.5.0_15

There are no specific issues with this setup. Can you connect to the DB using the exact same code from a desktop application?

By the way, you should remove the ".newInstance()" from the code. That's superfluous (and possibly harmful, depending on how the driver is written).

... and have you enabled TCP/IP support on your server instance? Have you configured your server to allow SQL Server authentication?

I haven't tried this...

have you enabled TCP/IP support on your server instance

I have read the manuals about How to manually enable TCP/IP on Windows XP sp 2 for SQL Server 2000
I added an open TCP port 1433 and name it SQL Server. I also added an open UDP port 1434 and name it SQL Server UDP.. However, the problem remains..
When I open command prompt and type netstat -an, both ports are not on the listening list. I also open the browser and go to the application..it throws the same error..

Have you configured your server to allow SQL Server authentication?

How can i do this ??
