One way to connect to a Salesforce instance is through the JDBC Driver Manager using the DriverManager.getConnection() method. This method specifies a string containing a connection URL. This example shows how to establish a connection to a data source:

Connection conn = DriverManager.getConnection
 ("jdbc:datadirect:sforce://login.salesforce.com;User=abc@defcorp.com;
   Password=secret;SecurityToken=XaBARTsLZReM4Px47qPLOS");
