title: Deploying to Heroku with my persistence.xml (JPA) without using Spring
body: <p>I have an error in application deployment with "git push master heroku" while locally it works fine.
  I want to use my <a href="https://github.com/rubyonrails-tutorial/forge/blob/master/src/main/resources/META-INF/persistence.xml" rel="nofollow">persistence.xml</a> for access to my data base of H2 (I will be use maybe PostgreSQL) all with my data source on WildFly 10.</p>
  
  <p>I found no reference other than the Spring. (I can not use it)</p>
  
  <p>Thank you!</p>
