Follow the steps below to connect a Java application to an Oracle database using Thin Driver.

  • Download Oracle JDBC Driver
  • Load Driver Class
  • JDBC Connection
  • Load the jar file
Download Oracle JDBC Driver:

Visit Oracle database website and download the Oracle JDBC Driver.

oracle jdbc jar file
Load Driver Class:

The Oracle database Driver Class is oracle.jdbc.driver.OracleDriver and the Class.forName(“oracle.jdbc.driver.OracleDriver”) method is used to load the Oracle database driver class.

JDBC Connection:

Make a connection to the Oracle database by following the given syntax:

Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:orcl", "system", "Password123")
Load the jar file:

We can load the.jar file in one of two ways:

  • Copy the jar file to the C:\Program Files\Java\jre7\lib\ext directory.
  • Set it on the classpath.
Simple Example:

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class JDBCExample {

    public static void main(String[] args) {
        // register JDBC driver, optional since java 1.6
        /*try {
        } catch (ClassNotFoundException e) {

        try (Connection conn = DriverManager.getConnection(
                "jdbc:oracle:thin:@localhost:1521:orcl", "system", "Password123")) {

            if (conn != null) {
                System.out.println("Connected to the database!");
            } else {
                System.out.println("Failed to make connection!");

        } catch (SQLException e) {
            System.err.format("SQL State: %s\n%s", e.getSQLState(), e.getMessage());
        } catch (Exception e) {
