流已关闭让我疯掉

   最近自己做个小系统玩 尝试下spring+webwork+hibernate，系统中还存在着一些问题，当然先把首要问题给解决掉，当我每次登录后，如果长时间没动作，再去点击新闻链接就会出现如下错误代码 一直修改 仔细检查都没找出错误 可能真的是学的太浅，所以希望有这方面经验的来帮忙解决下

我在AbstractService 文件中是通过这样获得对象

public class AbstractService extends HibernateDaoSupport{
......
	public Object load(Class classType, Serializable id)throws ServicesException {
		return (Object)this.getHibernateTemplate().load(classType, id);
	}
......
}

spring配置文件中我对事务等处理是这样配置的

	<bean id="baseTxProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" abstract="true">
		<property name="transactionManager">
			<ref bean="transactionManager" />
		</property>
		<property name="transactionAttributes">
			<props>
				<prop key="insert*">PROPAGATION_REQUIRED</prop>
				<prop key="update*">PROPAGATION_REQUIRED</prop>
				<prop key="delete*">PROPAGATION_REQUIRED</prop>
			<prop key="get*">PROPAGATION_REQUIRED</prop>

			</props>
		</property>
	</bean>

每当我长时间没动作后再 调用这个语句的时候

ericnews=super.getEricnewsAware().getEricNews(new Integer(this.id));

就会出现上面我列出来的错误，我已经快被折磨的疯掉了
