Struts2 配置文件中传参报错，大家帮忙看看，急
这是STRUTS的配置：<action name="addLine" class="action.MetroLineAction" method="addLine">
<result name="success" type="redirect">getLines?cityArea=${cityArea}</result>
</action>
ACTION中参数cityArea也有get、set：
public String getCityArea() {
return cityArea;
}
public void setCityArea(String cityArea) {
this.cityArea = cityArea;
}
这是外部包的引用：
报错信息如下：

--------------------编程问答-------------------- 1.把action声明都去掉，看能否正常；
2.试一下不带参数的路径getLines，看是不是有效；
3.把参数值写死了看行不行，如getLines?cityArea=1 --------------------编程问答--------------------
以上三种情况都是没问题的。 --------------------编程问答-------------------- getLines.action?cityArea=${cityArea} --------------------编程问答--------------------
这个也试过了，问题依旧
而且跳转类型也改过，都是一样。 --------------------编程问答-------------------- 结帖了，是包的问题，struts2配了xwork1，汗。 --------------------编程问答-------------------- ognl包的问题。。。
补充：Java , Web 开发
