    Possible bug: JPA's persistence.xml is deployed before datasources are created through application.xml

      Hello.

       

      So basically I'm creating a datasource through application.xml and referencing it in my persistence.xml.

      However when I try to deploy the EAR file, it fails because the datasource is being accessed before it was created.

      I did the following test:

       

      1 - Create a datasource before deploying the application

      2 - Deploy the application with a datasource to be created through application.xml

      3 - Now it works and both datasources exist (so no problem with the application.xml)

       

      I don't think it's important, but the JDBC driver is being deployed together with the EAR.

       

      So, my guess is that this is a bug in Wildfly, but I want to confirm with you guys.

       

      Is there an existing workaround for this, a configuration to be done or is creating the datasource before deploying the only way to avoid the issue?

       

      I'm using Wildfly 10.0.0.CR5 and was following this sample: javaee7-samples/jpa/datasourcedefinition-applicationxml-pu at master · javaee-samples/javaee7-samples · GitHub

       

      Thanks
