Question

我正在使用struts1.1。当我重定向到一个jsp文件时，我得到以下异常。我无法弄清楚错误的位置。

Answer 1

我通过将以下include标记更改为单个标记版本来修复此错误。

在：

<jsp:include page="..."></jsp:include>

我改变了这个，

<jsp:include page="..."/>

现在我没有得到这种类型的例外。

Answer 2

在我的情况下，我没有正确结束标记。如下。

<jsp:include page="..."＆GT;

我已将其更改为

<jsp:include page="..."/>

这解决了我的问题。

Answer 3

如果您未在同一行中关闭代码，则需要在<jsp:param name="someName" value="someValue" />

内设置<jsp:include></jsp:include>

Answer 4

我不得不更改它：

<jsp:forward page='redirect.jsp'>
</jsp:forward>

对此：

<jsp:forward page='redirect.jsp'/>

Answer 5

从weblogic迁移到tomcat服务器后，我的项目中也发生了此错误

实际上，如果您有<jsp:param name="xxx" value="yyy" />

，则可以在另一行中关闭标签

我的Tomcat服务器也不喜欢我有注释，所以我只删除了它们，然后它起作用了

<jsp:include page="/jsp/myJsp.jsp" flush="true">
     <jsp:param name="formName" value="someValueForm" />    <!-- it indicated the form to use -->
     <jsp:param name="someFunction" value="someFunction" />    <!-- a comment here --> </jsp:include>

Answer 6

当我在标签内发表评论时，我遇到了同样的错误。当我从该区块中删除评论时，它就起作用了。
