我正在尝试将数据添加到数据库并加载 12 类驱动程序，尝试 ojdbc14 和 ojdbc14_g 也出现以下错误

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException 
{
    Connection con = null;
    PreparedStatement ps = null;
    ResultSet rs = null;
    Statement st = null;
    PrintWriter pwinsert = response.getWriter();
    String firstname=request.getParameter("fname");
    String Ddate=request.getParameter("ddate");
    String Email=request.getParameter("email");
    String ContactNo=request.getParameter("contactNo");
    String Address=request.getParameter("address");
    String complaint=request.getParameter("complaint");
    String dept=request.getParameter("dept");
      try {
          Class.forName("oracle.jdbc.driver.OracleDriver");
          System.out.println("driver  loaded");
      }
      catch(ClassNotFoundException ex)    {
          System.out.println("driver not loaded");

      }


      String URL = "jdbc:oracle:thin:@localhost:1521:xe";
      String Username = "system";
      String Password = "toushif";
    try
    {


         con = DriverManager.getConnection(URL,Username,Password);
         ps = con.prepareStatement("INSERT INTO TOU (MOBILE,DDATE,NAME,EMAIL,ADDRESS,COMPLAINT,DEPT) VALUES (?, ?, ?, ?, ?, ?, ? )");
         ps.setString(1,ContactNo); 
         ps.setString(2,Ddate);
         ps.setString(3,firstname);
         ps.setString(4,Email);
         ps.setString(5,Address);
         ps.setString(6,complaint);
         ps.setString(7,dept);

         int i = ps.executeUpdate();
         pwinsert.println(i);

         if(i!=0)    {
             pwinsert.println("data has been stored");
         }
         else    {
             pwinsert.println("data could not be stored");
         }
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }

    // TODO Auto-generated method stub
}

}

收到此错误 java.sql.SQLException: No suitable driver found for jdbc:oracle:thin:@localhost:1521:xe

你应该使用

Class.forName("oracle.jdbc.OracleDriver");

不是

Class.forName("oracle.jdbc.driver.OracleDriver");

假设您jar在类路径上有权利。

oracle.jdbc.driver.OracleDriver被替换为oracle.jdbc.OracleDriverin 10g。
