Error deploying to standalone OC4J app server

Question

Hey all,
I created a web app with jdeveloper 10.1.3.3 using OC4J 10.1.3.3 as well. I'm using EJB and session beans to communicate with a database. nothing particularly fancy about it, i just read tables from the db. however, when i try and deploy through jdev to the standalone OC4J i get an error. here's the last part of the deployment log when it fails:
Deployment Log:
Binding ibmswauth web-module for application ibmswauth to site default-web-site under context root ibmswauth
Operation failed with error:
[ibmswauth:ibmswauth] - Exception creating EntityManagerFactory using PersistenceProvider class oracle.toplink.essentials.PersistenceProvider for persistence unit WD_WORK.
The only thing in my Persistence.xml file is the <persistence-unit> tag with name "WD_WORK", and in that a <jta-data-source> tag.
Also, it runs fine on the local embedded server, it's only when i try and deploy that it gives this error. I even deployed my app to an EAR file and tried uploading it manually to the app server, still same error.
any ideas?

If you have a model project that has objects referenced by the view controller/UI project then you need to explicitly include them in the deployment. Unlike in embedded OC4J they wont be automatically included.
Create an ADF library deployment profile in the model project and include the generated library in your UI project war file. You can add this jar to the project Libraries/Classpath then make sure it is included in the WEB-INF/lib Contributors list.
