json字符串转java对象数组

需要引入json-lib-2.2-jdk15.jar和ezmorph-1.0.6.jar包

1 String itemStar = request.getParameter("itemStar");
2         JSONArray json = JSONArray.fromObject(itemStar);
3         List<EvaluateDetail> list = (List<EvaluateDetail>)JSONArray.toCollection(json, EvaluateDetail.class);

在tomcat下运行正常，在jetty下运行报错
