Struts2 org.apache.jasper.jaspereException:找不到Struts dispatcher

struts.xml

    <action name="tohome" class="action.ToSmsAction" method="execute">
        <result name="success">/pages/home.jsp</result>
        <result name="login">/pages/login.jsp</result>
    </action>        

}

如果我没有包括

class=“action.tosmAction”

，那么它工作得很好

但是当

包括class=“action.tosmAction”

时，它会显示以下错误

HTTP Status 500 -

您需要提供额外的信息，主要是如何访问JSP页面。如果您直接访问JSP页面，并试图使用大多数S2标记，则会出现此错误。如果您阅读堆栈跟踪，它会告诉您发生此错误的大部分原因。要获得进一步帮助，您需要提供
