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, oracle.jdbc.pool.OracleDataSource. The Oracle implementation offers an extra method called setDriverType() to allow you to specify the driver type: "thin", "oci", or "kprb".

Here is a sample program that creates a connection object using the DataSource class without using JNDI services:

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

// Setting up the DataSource object
      oracle.jdbc.pool.OracleDataSource ds
        = new oracle.jdbc.pool.OracleDataSource();
      ds.setDatabaseName("XE"); // Oracle SID

// Getting a connection object
      con = ds.getConnection();

// Getting database info
      DatabaseMetaData meta = con.getMetaData();
      System.out.println("Server name: "
        + meta.getDatabaseProductName());
      System.out.println("Server version: "
        + meta.getDatabaseProductVersion());

// Getting the connection URL back
      System.out.println("Connection URL: "+ds.getURL());

// Closing the connection
    } catch (Exception e) {

The output confirms that I got a good connection. Remember to include ojdbc6.jar in the classpath for compilation and execution:

herong> javac -cp .;ojdbc11.jar

herong> java -cp .;ojdbc11.jar OracleDataSource

Server name: Oracle
Server version: Oracle Database 21c Express Edition Release 
  - Production

Connection URL: jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)

Note that the OracleDataSource class made up a connection URL string in a format very close to the TSN (Transport Network Substrate) definition.
