runtime error: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

Question

I am new to mysql and jdbc and I am getting the error in this title. I have been searching all day and cannot find a solution that works for me.

What I have tried:

Answer 1

I was also get same problem :-
How I solved for Linux system.

1.) Download file mysql-connector-java-5.1.18-bin.jar from given link or other.

2.) Then paste it to same folder or directory of your class or file (on where you want connection to present)

3.) Now use the following command by your linux command prompt.

java -cp .:mysql-connector-java-5.1.18-bin.jar YourFileName ..

Thats all you need to do... :)

Answer 2

You need to add a connector library to the Runtime classpath:

java -cp .;mysql-connector-java-5.1.25-bin.jar ClientBase

My example uses Windows classpath separator ";", on other systems it may be different (":" on Linux/Mac). It also assumes, that mysql-connector-java-5.1.25-bin.jar is located on the same folder. If it's not the case, then put a path to the library instead of the plain name.

ClientBase stands for Java class file name here

c:\>javac Test.java
c:\>java -cp .;F:\CK\JavaTest\JDBCTutorial\mysql-connector-java-5.1.18-bin Test

If You Are Using Swing you have to add External Jar of my-sql-connect

Answer 6

What did you import ? From the documentation: http://dev.mysql.com/doc/connector-j/en/connector-j-usagenotes-connect-drivermanager.html

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
// Notice, do not import com.mysql.jdbc.*
// or you will have problems!

Comment:

Why are you using notepad++ ? install an IDE (Eclipse/Netbeans/IntelliJ) - it'll be much easier to locate such problems (un-included jars for example)
