Hello!
I am creating a very simple test application using JPA, Wildfly as application server and Oracle Database 11g Express Edition as database.
The purpose of the Test class is to execute a People query. Whenever I run the Test class, the error appears "No Persistence Provider for Entitymanager named Project".
When I change the server to Tomcat 8 or Glassfish works normally, I just can’t get it to work on Wildfly. I’d really appreciate it if someone would help me.
Below is more information.

Thank you!
You are in a JEE container, can use
JTAand retrieve an EM from the CDI context. Still, if you want to use how you put it, add<provider>org.hibernate.ejb.HibernatePersistence</provider>in hispersistence.xml, may be just above the declaration ofclass, and see if it works. Something else is in the classpath when executing themain. See if there is indeed a preview JPA, besides trying to change thetransaction-type, removing.– Bruno César
I made the changes you suggested and it still doesn’t work. By changing the project to use a Datasource JTA and injecting Entitymanager, the Test class keeps giving error, this time returning me a java.lang.Nullpointerexception. Entitymanager is null, not being injected. The strange thing is that in Glassfish this same code works normally, only in Wildfly 8.2 that does not
