No Persistence provider for EntityManager named default [message #1008590]

Hy all,

during the migration of Oracle UIM 7.1.2 based on Kodo to 7.2 based on Eclipse link we get the error below in the code of Web Service in Java Language.

We also change the JPa provider from KODO to EclipseLink via WebLogic, but the error is the same.

Let me know if i have to share more details.

Thanks in advance

There are 2 errors. The first saying there isn't a provider for a 'default' persistence unit. Do you have a persistence.xml with a persistence unit named 'default'? More information such as the stack trace and configuration would be needed to debug this one further if it causes an issue with running the app - it is logged under the 'Notice' log level, so it might not be an issue.

The second indicates a persistence unit is successfully being used with a transaction, but that changes within the transaction violate a unique constraint. This would require looking into the application code to debug further.

Best Regards,
Chris

thanks vm for the feed, regarding the error, it could be related to a DB issue?

Thanks in advance

This's the error after have made this change

Adding uim-entities.jar in class path and persistence.xml of uim-entities.jar has following entry

<persistence-unit name="default" transaction-type="JTA">
<provider>
org.eclipse.persistence.jpa.PersistenceProvider
</provider>

You might want to take the first message to a WebLogic or UIM forum or support, because as I mentioned, it is showing up only as a notice not an error and there is no indication why it is occuring. Unless you are deploying a persistence unit named 'default', and are unable to deploy your application and use the persistence unit.

The second error is similar to the second error in the first post. This time, instead of a database constraint causing the transaction to fail, it is an optimistic lock exception. It shows that a persistence unit is deployed and working. The problem is an entity within the transaction is stale, and the exception is thrown to prevent overwriting with stale data. You need the full exception stack trace and to find out what the application is doing within the transaction.

Best Regards,
Chris
