Wildfly Persistenceunit Missing dependencies

Question

I am trying to make a Web Service using wildfly-10.0.0.Final

I am Getting the error Shown Bellow. I already copied/created postgres and eclipselink jars to the Wildfly module folders.

05:13:11,312 ERROR [org.jboss.as.controller.management-operation] (DeploymentScanner-threads - 1) WFLYCTL0013: Operation ("deploy") failed - address: ([("deployment" => "RESTendJPA-1.war")]) - failure description: {"WFLYCTL0180: Services with missing/unavailable dependencies" => ["jboss.persistenceunit.\"RESTendJPA-1.war#myPS\" is missing [jboss.naming.context.java.DefaultProject]"]}

I have created a datasource through Wildfly Administration UI. At the UI, wildfly Connects successfully to the datasource. The standalone.xml datasource Configuration is Shown Bellow.

<datasource jta="true" jndi-name="java:/DefaultProject" pool-name="DefaultProject" enabled="true" use-ccm="true">

Hi! The persistence Provider seems wrong to me.

<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>

As I recall Wildfly uses Hibernate so it would be the below:

<provider>org.hibernate.ejb.HibernatePersistence</provider>

Replace this in your persistence.xml and tell me if it worked.

• Tip: If you’re using the server dependencies and you’re letting it run with the dependencies, you don’t have to put that information in, because servers like Wildfly or Glassfish have a way of defining that leading to the implementation they’ve been embedding, is mandatory even on a Tomcat or Jetty that do not have this feature.

Tell us if it’s all right.
