I am using EclipseLink as a JPA Implementation. While deploying in Wildfly-10.1.0.Final, I always get the error No Persistence provider for EntityManager named <the persistence unit name>. I have followed the step in the links:
The steps and the module.xml exactly matches mine.In standalone.xml I have enabled the system property as stated in the first link mentioned above
I enabled the trace logging and found that the below : [org.hibernate.jpa.HibernatePersistenceProvider] (default task-4) Excluding from consideration due to name mis-match
Persistence Provider :org.eclipse.persistence.jpa.PersistenceProvider JDK Version :1.8
Request if someone can shed some light where I am going wrong.
Added the trace as
Caused by: javax.persistence.PersistenceException: No Persistence provider for EntityManager named AAAAA_BBBB
at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:61)
at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:39)

Was finally able to resolve the issue in a little weird way (probably)
Step 1 : created a module directory under the name (com.abc.persistence:main) Step 2 copied all the related jars of eclipselink and jipijapa into the same module and referred it.
Step 2. Removed the system property "eclipselink.archive.factory"
It works clean.
What I analysed was if one of the system property is put then others like the target server are never added to the properties map (I checked somewhere in the code). Once I removed I think all the others also gets added and hence it works, because I will be little surprised if creating the above directory in the module (Step 1 above ) made it work.
