Connecting to the Database

• The init method uses the Properties class to read the file
• Properties class has a load method to read a file of key/value pairs from a stream

  Properties props = new Properties();
  FileInputStream in = new FileInputStream(fileName);
  props.load(in);
  

• The getProperty method returns the value of a given key

  String driver = props.getProperty("jdbc.driver");
  

• Now when you need a connection call

  Connection conn = SimpleDataSource.getConnection();

• You need to close the connection by calling

  conn.close();
