The infamous java.sql.SQLException: No suitable driver found (23 answers)

Closed 8 years ago.

www.un.org/Depts/DGACM/index_french.htm

public static void insertIntoDatabase(String code,String name,String temp,String hum,String del) {
    Connection con = null;
    ResultSet rs = null;

    String url = "jdbc:mysql://localhost:3306/test";
    String user = "root";
    String password = "";

    try {
        Class.forName("com.mysql.jdbc.Driver");
        con = DriverManager.getConnection(url, user, password);
        rs = con.prepareStatement("CREATE TABLE IF NOT EXISTS AiportDetails(code VARCHAR(50) PRIMARY KEY, " +
                "name VARCHAR(50), temp VARCHAR(50), hum VARCHAR(50), del VARCHAR(50)) ENGINE=InnoDB;").executeQuery();
        rs = con.prepareStatement("INSERT INTO AirportDetails(code,name,temp,hum,del) VALUES("+code+","+
                name+","+temp+","+hum+","+del+");").executeQuery();
    } catch (SQLException ex) {
        ex.printStackTrace();
    } finally {
        try {
            if (rs != null) {
                rs.close();
            }
            if (con != null) {
                con.close();
            }

        } catch (SQLException ex) {
            ex.printStackTrace();
        }
    }
}

I am getting the following error:

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

NOTE Some common corrections I found online were:

1. The driver is not in the /WEB-INF/lib folder.
2. The url is wrong.

I dont think this is the case with my code.
Thank you.

Answer 1

That can happen if you didn t load the driver before making the first connection ever.

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

当然,司机必须填写在<代码>/WEB-INF/lib上,而不是在<代码>/WEB-INF上。你们用某种卡片喷洒的洞。见PreparedStatement。 www.un.org/chinese/sc/presidency.asp 还可以改进,正如你现在所做的那样,<条码>con永远不会在<条码>上填写。
