{
success:0,
errorMsg:"错误消息",
data:{
total:"总记录数",
rows:[
{
id:"任务ID",
workName:"任务名称",
assigneeName:"经办人姓名",
name:"流程步骤名称",
processInstanceInitiatorName:"发起人",
processInstanceStartTime:"发起时间",
createTime:"到达时间",
dueDate:"截止时间"
},
{

assigneeName:"经办人",
name:"流程",
processInstanceInitiatorName:"发起人",
processInstanceStartTime:"发起",
createTime:"到达",
dueDate:"截止"

解析出数据:

json-lib-2.4-jdk15.jar  这个包还另需一下几个包。

jakarta commons-lang 2.5
jakarta commons-beanutils 1.8.0
jakarta commons-collections 3.2.1
jakarta commons-logging 1.1.1
ezmorph 1.0.6
