本文探讨了使用Hibernate 3.5.6与Oracle 10g时遇到的初始化异常问题，该异常虽然不影响应用程序正常运行，但可能带来不必要的困扰。文章提供了两种解决方案：一是禁用Hibernate尝试从数据库检索元信息的功能；二是通过配置文件调整属性来消除异常。

I am using using hibernate 3.5.6 with Oracle 10g. I am seeing the below exception during initialization but the application itself is working fine. What is the cause for this exception? and how it can be corrected?

First Way:

As you noticed, this exception isn't a real problem. It happens during the boot, when Hibernate tries to retrieve some meta information from the database. If this annoys you, you can disable it:

hibernate.temp.use_jdbc_metadata_defaults false


Second Way:

To get rid of the exception

INFO - HHH000424: Disabling contextual LOB creation as createClob() method threw error :java.lang.reflect.InvocationTargetException

In hibernate.cfg.xml file add below property

<property name="hibernate.temp.use_jdbc_metadata_defaults">false</property>
