Deploying Hibernate Apps on OC4J
I’ve spent a good deal of time today trying to deploy an application I’ve recently completed on Oracle IAS 10g. I still haven’t decided if I like the beast or not. I already knew about the bug regarding the antlr.jar, but in the past I dealt with it by renaming the antlr.jar in the toplink directory under JDeveloper. Since I had to deploy on a server that already hosts a dozen of other applications developed by other people, this was not an option.
Luckily, it wasn’t very hard to figure out my way. After tweaking the deployment options for a while, I noticed on the third step of the deployment wizard, there was an option to modify classloading. I turned of loading of the toplink library for my app, and voila. It started working like a charm.
A quick note for the people who has no idea about this issue: The antlr.jar version required by the hibernate causes problems since a different version of antlr is included with the toplink library.
My Setup: Oracle IAS 10.1.3.3 on Linux
