How can I configure glass fish to use application managed entity managers?

Question

How can I configure glass fish to use application managed entity managers? I get the following error with the configuration given below.

I do not want glassfish to manage transactions, I want to only use spring managed transactions with RESOURCE_LOCAL setting, not JTA, in the persistence unit

SEVERE: Exception while preparing the app : The persistence-context-ref-name [org.springframework.data.jpa.repository.support.JpaRepositoryFactoryBean/entityManager] .... resolves to a persistence unit called [spring-jpa] which is of type RESOURCE_LOCAL. Only persistence units with transaction type JTA can be used as a container managed entity manager. Please verify your application.

My Cofiguration:

<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
  <persistence-unit name="spring-jpa" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <non-jta-data-source>mysql/mydb</non-jta-data-source>
    <properties/>
  </persistence-unit>
</persistence>

I found this forum post, I quote:

In a Java EE environment, if this element [transaction-type] is not specified, the default is JTA. In a Java SE environment, if this element is not specified, a default of RESOURCE_LOCAL may be assumed.

So, in your configuration try:

<persistence-unit name="spring-jpa" transaction-type="JTA">
