hi guys, i used the following code to try to connect to sql server 2005.
          try {             Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");             Connection conn = DriverManager.getConnection("jdbc:sqlserver://localhost;integratedSecurity=true");                   } catch (Exception e) {             e.printStackTrace();         }
and i got the following exception:
com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host  has failed. java.net.ConnectException: Connection refused: connect         at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDriverError(Unknown Source)         at com.microsoft.sqlserver.jdbc.SQLServerConnection.connectHelper(Unknown Source)         at com.microsoft.sqlserver.jdbc.SQLServerConnection.loginWithoutFailover(Unknown Source)         at com.microsoft.sqlserver.jdbc.SQLServerConnection.connect(Unknown Source)         at com.microsoft.sqlserver.jdbc.SQLServerDriver.connect(Unknown Source)

Answer 1

The error is probably caused by the port number where the SQL Server is listening for the client connection.
If port number is different than the default number, you must specify the port number in the connection url
Also check the API for getConnection
[http://java.sun.com/j2se/1.4.2/docs/api/java/sql/DriverManager.html]
Connection conn = DriverManager.getConnection("jdbc:sqlserver://localhost:portnumber;username,password");
