tomcat没访问几次就歇菜了~
//创建session
public static Session getSession(){
Configuration config = new Configuration().configure();
SessionFactory factory = config.buildSessionFactory();
Session session = factory.openSession();
return session;  
}
//其中一个dao
//增加图片

Session session = DBUtil.getSession();
Transaction t = session.beginTransaction();
boolean falg = false;

falg= true;
session.save(img);

没有连接池
tomcat也没有设置任何东西，应该我的程序有问题··谁能帮忙看看，顺便解决下，谢谢~~
··还有数据库如果用oracle，当V$session这张表 达到150左右就会报错··是什么原因呢

------解决方案--------------------
session有个disconnect方法吧
------解决方案--------------------
报的是数据库连接池达到最大数了吧。你应该加一个数据库连接池。分区进行设置。
