本文介绍了NetBeans Hibernate中的NullPointerException从Firebird数据库映射文件和POJO向导的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在开发一个使用netbeans，hibernate和firebird的桌面应用程序。
向导不会给我创建文件带来麻烦hibernate.cfg.xml，
或HibernateUtil.java
但是通过尝试：新建 - >其他 - > Hibernate - > Hibernate从数据库映射文件和POJO，使用我的hibernate.cfg.xml和hibernate .reveng.xml
向导抛出异常：
Hibernate配置失败，出现消息：java.lang.NullPointerException message.log查看exception 。 IDE 7.2.1（Build 201210100934）

解决方案
I'm developing a desktop application using netbeans, hibernate and firebird.
The wizard does not give me trouble creating files hibernate.cfg.xml,or HibernateUtil.java
But by trying: New -> Other -> Hibernate -> Hibernate Mapping Files and POJOs from Database, using my hibernate.cfg.xml and hibernate.reveng.xmlthe wizard throws the exception:
Hibernate configuration fails with message: java.lang.NullPointerException message.log see exception for details.

解决方案
A new question about this triggered me to investigate it again, the problem is a combination of how Jaybird loads itself and a custom classloader in Netbeans. See https://stackoverflow.com/a/18920383/466862
这篇关于NetBeans Hibernate中的NullPointerException从Firebird数据库映射文件和POJO向导的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
