---------------我的jsp页面:
<form name="listmsgs" method="post">

------------------java:
request.setAttribute("ComList",itera); itera是个数组，里面有值

---

是从action中转发到该jsp页面吗？

---

可能你在页面传递的时候中间多了一层，你先试试放在session中看可以不

---

是的，是从action中转发到jsp页面

我是初学，我访如何先放在session中呢?

---

session.attribute(“对象名”，对象);

---

HttpSession session = request.getSession();
session .setAttribute("ComList",itera);

---

放在session中不是好办法，这个只是为了检查你的错误是不是由于request的丢失造成的。如果session中能取到，说明的forword的时候有没对的地方

---

自己发现问题所在了：
测试的时候我在IE里浏览的是Http://.........XXX.jsp
这样就会产生上述的错误，如果我用http://............xxx.do程序就是正确的，上述问题应该是程序里的request.的机制问题
谢谢大家!
