struts2-json-plugin-2.1.8.1引发的错误

最近在使用Ajax调用action获取数据时提示如下错误：

java.lang.NoClassDefFoundError: org/apache/commons/lang/xwork/StringUtils

经过几番苦战，尝试各种办法调试，最后发现不是写法的问题，而是struts2-json-plugin版本的问题；从目前的经验来看，我遇到的大部分问题都是jar包不全或者版本不匹配导致的。

这个是struts2-json-plugin-2.3.8的下载地址：

http://download.csdn.net/download/huangbye/7694131

详细错误如下：

记录struts2 json plugin 对字符串数组类型的处理

当前项目中,一开发人员在action中定义了一个字符串数组类型的属性,需要以json格式返回到页面(先不论这种设计是否最优), 结果在做页面调试时发现总是无法在ajax的success方法中获取到该属性.后台action调试发现该数组已经正确赋值,get 方法也没有问题,action相关代码如下: private String[] traceList; private String unitName; ... public String queryTrace(){ unitName = "tes
