Using Java to connect to an Oracle database

Question

This Java code compiles fine, but when I try to run it I get:

Exception in thread "main" java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

Here is my code:

import java.sql.*;

public class TestConnection {

    public static void main(String[] args) throws Exception {
        //connect to database
        Class.forName("oracle.jdbc.driver.OracleDriver");
        String serverName = "000.000.000.000";
        String portNumber = "1521";
        String sid = "abcd";
        String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber + ":" + sid;
        String username = "user";
        String password = "pass";
        Connection conn = DriverManager.getConnection(url, username, password);
    }
}

How do I get this to work? I am using Ubuntu 11.04 and JDK 6.

Thanks!

You need to download the Oracle JDBC driver and put it on your classpath. — Alex, Jun 18 '12 at 18:50

You need the Oracle jars.

You can get them from here.

You'll probably want to grab ojdbc6.jar from that link. – Windle Jun 18 '12 at 18:57
It says: ojdbc6.jar (2,714,189 bytes) - Classes for use with JDK 1.6. But I have JDK 6?? – bumbleshoot Jun 18 '12 at 19:08
Ah I see, they are the same: http://www.oracle.com/technetwork/java/javase/version-6-141920.html – bumbleshoot Jun 18 '12 at 19:13

If you're using Maven:

<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc6</artifactId>
    <version>11.2.0</version>
</dependency>

is it still present in mvn repo ? – Rodislav Moldovan Mar 21 '14 at 12:22
It's not public right now. I had to register previously in the Oracle Maven Repository. More info here: [link](https://docs.oracle.com/middleware/1213/core/MAVEN/config_maven_repo.htm#MAVEN9010) – Pablo Insua Dec 08 '17 at 19:04

Add ojdbcXX.jar-where XX is version number-to Java build path of your project. Aside from the classpath issue, requesting "oracle.jdbc.driver.OracleDriver" is deprecated. For a long time it has been recommended to use: "oracle.jdbc.OracleDriver". For some more recent driver versions, the former will not even work.

Why that jar? And where can I get it? – bumbleshoot Jun 18 '12 at 19:11
Oh no sorry you would use ojdbc6.jar as this is for java 6. (1.6 is the same as 6 naming conventions for java changed). The one i referenced was for java 1.4! – David Kroukamp Jun 18 '12 at 19:14

Also, you have to add those jars to your project. @Netbeans, you can easily do that at the project-properties
