I use the MySQL 5.5 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”); Previous connection = drivermanager getConnection(MysqLUrl,userInfo); I got Java lang.ClassNotFoundException:com. MysqL. jdbc. Driver
Solution
Attempt to insert:
DriverManager.registerDriver(new com.MysqL.jdbc.Driver());
