点注册以后，出不来页面的问题，请高手们帮忙看看

[fangjianwang]

我在SSH下一个注册登陆程序，我在注册页面上填写完注册信息以后，点注册后出现一片空白。请高手们看看大概是那里出错了。以下是在Tomcat5.0中logs中的信息：

getOutputStream()已经被执行过一次了。不能获取第二次

[yakjuly]

getOutputStream() has already been called for this response 是注册码 的图片问题 要改下
不过好象不会造成空白页面的问题

你哪儿看出来的？

[insertinsertinsert]

getOutputStream() has already been called for this response
已经被运行过了，不能再调用，自己查看下代码！
