谁能帮我看看啊，真是不会弄了
到底是怎么回事啊。求解答。 --------------------编程问答-------------------- 项目名上右键--〉myeclipse-->add hibernate capabilites -->next-->hibernate config file --> existing -->选择现有工程存在的hibernate配置文件--> next --> 不生成factory class --> end

大概是这样。为什么连接不上啊。 --------------------编程问答-------------------- 检查下你的配置对不对，用户名密码什么的还有其他的配置，报错说打不开链接，还有就是有没有导入数据库的驱动。 --------------------编程问答-------------------- 连的是什么数据库？
把你的配置文件贴贴 --------------------编程问答--------------------
都有啊。我是复制粘贴的，以前的一个项目都能用不知道为什么到这就不行了。 --------------------编程问答--------------------

用户名和密码就先不给你看了因为是公司的代码。 --------------------编程问答-------------------- oracle的话，看看服务是否已启动
补充：Java , Web 开发
