Java EE Ear application deployment failing -- javaDB persistance issue

Question

I know why it's failing -- it can't find the resource I've specified in the persistence.xml file. Which is purely wrong. I created the database, and connected it to netbeans. What I don't know is why there's extra characters for the resource name in the errors below.

The resource should exist and be available. Netbeans connected to it just fine. So why isn't the EAR finding it? What am I doing wrong? How do I fix.

Any other info needed just let me know.

Persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

      <property name="javax.persistence.schema-generation.database.action" value="create"/>
    </properties>
  </persistence-unit>
</persistence>

Answer 1

So, Turns out the removing the below line from the persistence file let it work.

<jta-data-source>users</jta-data-source>
