[java] How to add the JDBC mysql driver to an Eclipse project?

1. I have downloaded the mysql-connector-java-5.1.24-bin.jar
2. I have created a lib folder in my project and put the jar in there.
3. properties of project->build path->add JAR and selected the JAR above.
4. I still get java.sql.SQLException: No suitable driver found for jdbc:mysql//localhost:3306/mysql

I am using mysql 5.5 The code:

package DBTest;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.sql.*;
import java.util.*;

/**
 * Servlet implementation class TenUsers
 */
@WebServlet("/TenUsers")
public class TenUsers extends HttpServlet {
    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        PrintWriter out = response.getWriter();
        String mySqlUrl = "jdbc:mysql://localhost:3306/mysql";

        Properties userInfo = new Properties();
        userInfo.put("user", "root");
        userInfo.put("password", "SabababArba");
        try{
            Connection connection = DriverManager.getConnection(mySqlUrl, userInfo);
        }catch(Exception e) {
            out.println(e);
        }      
    }
}

If I add Class.forName("com.mysql.jdbc.Driver"); before Connection connection = DriverManager.getConnection(mySqlUrl, userInfo); I get java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

if you are getting this exception again and again then download my-sql connector and paste in tomcat/WEB-INF/lib folder...note that some times WEB-INF folder does not contains lib folder, at that time manually create lib folder and paste mysql connector in that folder..definitely this will work.if still you got problem then check that your jdk must match your system. i.e if your system is 64 bit then jdk must be 64 bit

you haven't loaded driver into memory. use this following in init()

Class.forName("com.mysql.jdbc.Driver");

Also, you missed a colon (:) in url, use this

String mySqlUrl = "jdbc:mysql://localhost:3306/mysql";

Try this tutorial it has the explanation and it will be helpful http://www.ccs.neu.edu/home/kathleen/classes/cs3200/JDBCtutorial.pdf

You can paste the .jar file of the driver in the Java setup instead of adding it to each project that you create. Paste it in C:\Program Files\Java\jre7\lib\ext or wherever you have installed java.

After this you will find that the .jar driver is enlisted in the library folder of your created project(JRE system library) in the IDE. No need to add it repetitively.

1: I have downloaded the mysql-connector-java-5.1.24-bin.jar

Okay.

2: I have created a lib folder in my project and put the jar in there.

Wrong. You need to drop JAR in /WEB-INF/lib folder. You don't need to create any additional folders.

3: properties of project->build path->add JAR and selected the JAR above.

Unnecessary. Undo it all to avoid possible conflicts.

4: I still get java.sql.SQLException: No suitable driver found for jdbc:mysql//localhost:3306/mysql

This exception can have 2 causes:

1. JDBC driver is not in runtime classpath. This is to be solved by doing 2) the right way.

2. JDBC URL is not recognized by any of the loaded JDBC drivers. Indeed, the JDBC URL is wrong, there should as per the MySQL JDBC driver documentation be another colon between the scheme and the host.

   jdbc:mysql://localhost:3306/mysql
   

1. copy mysql-connector-java-5.1.24-bin.jar

2. Paste it into \Apache Software Foundation\Tomcat 6.0\lib\<--here-->

3. Restart Your Server from Eclipes.

4. Done
