}我设法创建了模板，并在没有"名称"属性的表单中调用。它工作，然后我意识到我必须调用具有名称属性（CommentsUpdated）的表单，以便我能够传递从数据库中挖掘数据的变量。不幸的是，它抛出这样的错误：javax.servlet.jsp.JspException: Cannot find bean: "CommentsUpdated" in any scope.
我知道我的serachMyUser.jsp中的name属性导致了这个错误，但是我被这个部分卡住了，我试着在google中搜索例子，但是我得到的所有结果都是表单被调用时没有names属性。

最后我发现了这个问题，当我在struts-config.xml的活动中输入
name="CommentsUpdated"后，它工作了！希望这对其他人也有帮助！unguejic2#
如果您没有在操作配置中设置
name属性（该属性应该与<form-bean>名称相同），但在标记中使用了名称你当然有例外
找不到Bean：任何范围内的"CommentsUpdated"
Struts会示例化一个form-bean，如果配置了表单bean和动作名称，就会把它传递给动作。如果你想自己示例化它，那么你应该在JSP中访问它之前把它放在任何作用域中。
