请问这个JSP的SESSION为什么是NULL
在session_login.html里面提交name 
  <html>  
  <head>  
  <meta   http-equiv= "Content-Type "   content= "text/html;   charset=gb2312 ">  
  <title> 无标题文档 </title>  
  </head>    
  <body>  
  <form   name= "form1 "   method= "post "   action= "check.jsp ">  
        <label> name 
        <input   type= "text "   name= "name ">  
        </label>  
 	 <br>  
 	 <input   name= "ok "   type= "submit "   value= "提交 ">  
  </form>  
  </body>  
  </html>  
 在check.jsp里面写入session 
  <%@   page   contentType= "text/html;   charset=gb2312 "   language= "java "   import= "java.sql.* "   
errorPage= " "%>  
  <html>  
  <head>  
  <meta   http-equiv= "Content-Type "   content= "text/html;   charset=gb2312 ">  
  <title> 无标题文档 </title>  
  </head>    
  <body>  
  <% 
 String   name   =   request.getParameter( "name "); 
 session.setAttribute( "name ",name); 
 response.sendRedirect( "success.jsp "); 
 %>  
  </body>  
  </html>  
 在success.jsp页面里面读出session 
  <%@   page   contentType= "text/html;   charset=gb2312 "   language= "java "   import= "java.sql.* "   errorPage= " "   %>  
  <html>  
  <head>  
  <meta   http-equiv= "Content-Type "   content= "text/html;   charset=gb2312 ">  
  <title> 无标题文档 </title>  
  </head>    
  <body>  
  <%=request.getAttribute( "name ")%>  
  </body>  
  </html>  
 现在这三个页面均可以执行   在name表单里输入内容后   在最后的   =request.getAttribute( "name ")出来的值是null 
 请问是不是有什么不对的地方
------解决方案--------------------应该是session.getAttribute( "name ")吧,你试一下
------解决方案--------------------应该是: <%=session.getAttribute( "name ")%>
