报什么错

没报错。。。

你参考一下我这个吧。我这个也是注册的。直接在JSP页面写的，没有进行Servlet或者其他方法调用之类的
String clientName=request.getParameter("clientName");
    String clientTelephone=request.getParameter("clientTelephone");
    String clientAddress=request.getParameter("clientAddress");
    String clientEmail=request.getParameter("clientEmail");
    Connection conn=null;
    Statement st=null;
    ResultSet rs=null;
    try{
        Class.forName("com.mysql.jdbc.Driver");
        String url="jdbc:mysql://localhost:3306/system-1001";
        conn=DriverManager.getConnection(url,"root","");
        st=conn.createStatement();
        String sql="INSERT INTO factory_client VALUES('"+clientName+"','"+clientTelephone+"','"+clientAddress+"','"+clientEmail+"')";
        //String sql="INSERT INTO factory_client VALUES('Tony','13983120982','ChongQing','13983120982@')";
        st.executeUpdate(sql);
        response.sendRedirect("../client/success.jsp");
    }catch(Exception e){
        e.printStackTrace();
    }finally{
        st.close();
        conn.close();
