  </head>
  
  <body>
   <%
   String rand1=request.getParameter("rand1");
   String rand=(String)session.getAttribute("rand");
   if(!rand1.equals(rand))
   {
   out.println("验证码出错");
   response.sendRedirect("login.jsp");}
   
    %>
  </body>
</html>
我在webproject下的src中创建了一个MyBean的包存放dbcon的JavaBean但是在jsp运行中却出现check.jsp (line: 3, column: 0) The value for the useBean class attribute package.dbcon is invalid.求各位大侠指教
