Using Hibernate in OC4J 10.1.3.x

This is as much a note for my own future reference as well as a couple tips for others.

Here's my trail of discovery :
- Using Hibernate with Applications in OC4J

- Removing and/or Replacing an Oracle Shared Library Imported by Default

- Load Local Classes in WAR Module in Preference to Classes loaded at Higher Level

So starting from the top, you need to fix the conflict where OC4J's TopLink loads a version of Antlr not compatible with the version Hibernate requires. This is done with a change to orion-application.xml. I thought that this change would suffice but found that a change was needed in orion-web.xml as well.

I didn't know this stuff without some investigation. These entry might be a quick start for others using Hibernate in OC4J.

orion-application.xml

<imported-shared-libraries>
<remove-inherited name="oracle.toplink"/>
</imported-shared-libraries>

orion-web.xml

<web-app-class-loader search-local-classes-first="true" include-war-manifest-class-path="true" />

Flex makes it really easy to grab some data and pump it into the nice charts in its API. Check out this baby.



Cool hey.
