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

         
          false
