struts的action访问老是有错误，不知道是怎么回事

这是struts2.xml文件

<?xml version="1.0" encoding="UTF-8" ?>

这是note.xml文件

这是project.xml文件

<?xml version="1.0" encoding="UTF-8" ?>

<action name="DeleteProject"

<!-- 居然也是和 DeleteProjectIndex执行相同的查询 -->
<action name="MyProjectIndex"
class="com.TeamManage.action.projectAction.UpdateProjectIndexAction">
<result name="success">/seeProject.jsp</result>
<result name="error">/seeProject.jsp</result>
</action>


<!--查看具体的项目 -->
<action name="SeeTask" class="com.TeamManage.action.projectAction.SeeTaskIndex">
<result name="success">/seeTask.jsp</result>
<result name="error">/seeTask.jsp</result>
</action>
</package>
</struts>

这是resource文件

这是task文件

这是错误的提示信息，有部分action能访问，有些却不能，有时候却变得有时候能访问，有时候却不能访问，我用的Eclispe EE 版本Version: Mars.2 Release (4.5.2)
