Netbeans Hibernate映射文件中的NullPointerException和Firebird数据库中的POJO向导
我正在使用netbeans，hibernate和firebird开发桌面应用程序。
该向导不会给我创建文件hibernate.cfg.xml或HibernateUtil.java带来麻烦
但是通过尝试：New – > Other – > Hibernate – > Hibernate Mapping Files和来自Database的POJO，使用我的hibernate.cfg.xml和hibernate.reveng.xml向导抛出exception：
Hibernate配置失败，并显示消息：java.lang.NullPointerException message.log请参阅exception以获取详细信息。
我正在使用
产品版本：NetBeans IDE 7.2.1（Build 201210100934）
Java：1.7.0_11; Java HotSpot（TM）客户端VM 23.6-b04
系统：在x86上运行的Windows XP 5.1; CP1252; es_ES（nb）
Firebird版本：2.1.1
的hibernate.cfg.xml
org.hibernate.dialect.FirebirdDialect org.firebirdsql.jdbc.FBDriver jdbc:firebirdsql://ip_from_my_server:3050/path_to_my_database.gdb sysdba masterkey HibernateUtil.java

hibernate.reveng.xml中

关于这个的一个新问题引发了我再次调查它，问题是Jaybird如何加载自身和Netbeans中的自定义类加载器的组合。 请参阅https://stackoverflow.com/a/18920383/466862
删除hibernate.cfg.xml和hibernate.reveng.xml; 并使用Netbeans再次生成它们。 之后尝试创建实体类。 我遇到过这个问题，这对我有用
