Answer 1

dwr 配置：
<create creator="spring" javascript="quest" scope="application">
<param name="beanName" value="questService" />
<include method="getTaskSql"/>
<include method="getTaskRows"/>
<include method="getTaskResult"/>

Answer 2

你是不是hibernate有外键链接？如果有请在外键主键设置lazy=false属性。这是延迟加载出错。就是加载的时候把外键的表数据也加载出来。

Answer 3

该问题应该是你的在别的地方使用的session时报的错，应为此时session已经关闭
