谁帮我看看，这2个代码有啥不一样?报错

1.<form id="payform" name="payform" action="http://ceshi.allinpay.com/gateway/index.do" method="post">

2.<form id="payform" name="payform" action="http://ceshi.allinbuy.com/gateway/index.do" method="post">

今天在整，通联的支付接口。

上面2个同样的东西，第一个写法就能正常访问，可是第二2个就报错，

<%--<form id="payform" name="payform" action="http://ceshi.allinpay.com/gateway/index.do" method="post">--%>

</form>

换成第一个就能提交成功，可是第二个，死活不争取，吐血，实在是看不出来什么地方不一样，求教
