一个Hibernate+weblogic的问题

[maidongdong]

本人用weblogic+hibernate+struts做开发，根据网上的资料做了一个HibernateStartUp类，随着weblogic服务器的启动而加载启动，目的是注册hibernate的SessionFactory.

如果不用上面说的方式，在DAO中做如下处理：
SessionFactory sessionFactory = new Configuration()
.configure()
.buildSessionFactory();
session = sessionFactory.openSession();
可以得到预期的结果，但事实上不可能只有一个DAO，而不可能在每个DAO中都创建SessionFactory实例。

所以我打算还是采用本文一开始提到的方式，这样就需在startWeblogic.cmd中设置HibernateStartUp的classpath，如是我做了如下修改：

@REM Set HibernateStartUp classpath

set Hibernate_StartUp=D:\SunJava\bea\user_projects\domains\mydomain\applications\bookonl
ine\WEB-INF\classes

set Hibernate_lib=D:\SunJava\bea\user_projects\domains\mydomain\applications\bookonline\
WEB-INF\lib

set CLASSPATH=%Hibernate_StartUp%;%Hibernate_lib%;%CLASSPATH%

(同时我也参阅了一些有关classLoader的文章（AppServer classLoader,ejb classLoader,web classLoader),自认为做了如上设置应该不会有什么问题了），但是事与愿违，还是出错了，如下：）
