My SQL server instance name is MYPC \ SQLEXPRESS and I'm trying to create a jTDS connection string to connect to the database I am 'blog' Can anyone help me out?

I am trying to do this: 

  DriverManager.getConnection ("jdbc: jtds: sqlserver: //127.0.0.1: 1433 / blog", "user "," password ");

And I get it: 

  java.sql.SQLException: Network error IOException: Connection refused on net.sourceforge.jtds.jdbc.ConnectionJDBC2 Connect. & Lt; Init & gt; At net.sourceforge.jtds.jdbc.ConnectionJDBC3 (ConnectionJDBC2.java:395). & Lt; Init & gt; On net.sourceforge.jtds.jdbc.Driver.connect (ConnectionJDBC3.java:50) (Driver.java: main.main (java.sql.DriverManager.getConnection (Unknown Source SqlConnection.Connect on main.java:11) ( SqlConnection.java:19) caused java.sql.DriverManager.getConnection (unknown source) at 184)) by: java.net.ConnectException: connection refused: java.net on java.net.PlainSocketImpl.connectToAddress in Java.

JTDS is the URL format for jTDS: 

  JDBC: jtds: & lt; SERVER_TYPE & gt ;: // to & lt; Server & gt; [: & Lt; Harbor & gt;] [/ & lt; Database & gt;] [;   
 Therefore, to connect to a database called "Blog" hosted by an MS SQL server running on  MYPC, & lt; Property & gt; = & Lt; Value & gt; , you might end up with something like this: 
 
  jdbc: jtds: sqlserver: // MYPC: 1433 / blog; Example = If you  getConnection (url, "There sa want to use", "s3cr3t"), then / s> > 
  jdbc: jtds: sqlserver: // MYPC: 1433 / blog; Example = SQLEXPRESS  
 
  Edit:  Your  refused connection with connection , double check that you have SQL Running the server, the service is running and you do not have a firewall incoming connection blocked.
