Creating Connections with DataSource Class

This section describes how to create connection objects with the DataSource class.

It is recommended now that connection objects are created by the DataSource implementation class, Here is a sample program that creates a connection object using the DataSource class without using JNDI services:

 - Copyright (c) 2015,, All Rights Reserved.
import java.sql.*;
public class SqlServerDataSource {
  public static void main(String [] args) {
    Connection con = null;
    try {

// Setting up the DataSource object ds 
        = new;
//      ds.setPortNumber(60782);
// Getting a connection object
      con = ds.getConnection();
// Database and driver info
      DatabaseMetaData meta = con.getMetaData();
      System.out.println("Server name: " 
        + meta.getDatabaseProductName());
      System.out.println("Server version: "
        + meta.getDatabaseProductVersion());
      System.out.println("Driver name: "
        + meta.getDriverName());
      System.out.println("Driver version: "
        + meta.getDriverVersion());
      System.out.println("JDBC major version: "
        + meta.getJDBCMajorVersion());
      System.out.println("JDBC minor version: "
        + meta.getJDBCMinorVersion());
// Closing the connection
    } catch (Exception e) {
      System.err.println("Exception: "+e.getMessage());

The output confirms that I got a good connection. Remember to include sqljdbc42.jar in the classpath for compilation and execution:

   -cp .;\local\lib\sqljdbc42.jar

   -cp .;\local\lib\sqljdbc42.jar SqlServerDataSource

Server name: Microsoft SQL Server
Server version: 12.00.2000
Driver name: Microsoft JDBC Driver 4.2 for SQL Server
Driver version: 4.2.6225.100
JDBC major version: 4
JDBC minor version: 2

The output also confirms that sqljdbc42.jar supports JDBC API 4.2.
