请问一下：JSONObject data = obj.getJSONObject("data");

这句中data是哪里的参数？

请问下这个问题是怎么解决的。

照样子写了个,可是这个j执行时出错
JSONObject obj=queryWaitTasks(request);是得到数据的内容是对的
{"message":"","ext":"","flag":true,"stack":"","customer":"0","ver":"0","md5":"","code":"","reason":"","aCode":"","data":{"value":{"rows":[{"StartTime":{"changed":"0","value":"2015-04-23T14:58:00.000Z","originalValue":null},"TaskStateName":{"changed":"0","value":"执行中","originalValue":null},"Topic":{"changed":"0","value":"任务来了","originalValue":null},"t":{"changed":"0","value":"D54FBF4E9AE04A7DBC952F99D8CFC0B9","originalValue":null},"userdata":{"recordState":null},"Ratio":{"changed":"0","value":null,"originalValue":null}},{"StartTime":{"changed":"0","value":"2015-04-10T15:11:37.000Z","originalValue":null},"TaskStateName":{"changed":"0","value":"执行中","originalValue":null},"Topic":{"changed":"0","value":"第二个任务","originalValue":null},"t":{"changed":"0","value":"97A5762A0F984FF299DD09E6F0686E33","originalValue":null},"userdata":{"recordState":null},"Ratio":{"changed":"0","value":null,"originalValue":null}}],"@type":"table","userdata":{"relationTypes":"String,String,DateTime,String,Float","relationAlias":"t,Topic,StartTime,TaskStateName,Ratio","relations":"CRM_Task,CRM_Task.Topic,CRM_Task.StartTime,CRM_Task.TaskStateName,CRM_Task.Ratio","model":"/CRM/Common/data","updateMode":"whereVersion"}}},"guid":"0","messages":"[]"}

可是JSONObject data = obj.getJSONObject("data");就是报错
