According to the schema for web.xml I can define a persistence-contect-ref that would allow me access to the EntityManager that would allow me to inject it into a Servlet.
<persistence-context-ref>
<persistence-context-ref-name>persistence/em</persistence-context-ref-name>
<persistence-unit-name>my-pu</persistence-unit-name>
</persistence-context-ref>
And according to ejb-jar.xml schema, I could define a persistence-context-ref that would allow me access to the EntityManager in an EJB that I could define in my test classes of my project.
<enterprise-beans>
<session>
<ejb-name>AppTest</ejb-name>
<ejb-class>org.acme.AppTestBean</ejb-class>
<session-type>Stateless</session-type>
<persistence-context-ref>
<persistence-context-ref-name>persistence/my-pu/em</persistence-context-ref-name>
<persistence-unit-name>my-pu</persistence-unit-name>
</persistence-context-ref>
<persistence-unit-ref>
<persistence-unit-ref-name>persistence/my-pu/factory</persistence-unit-ref-name>
<persistence-unit-name>my-pu</persistence-unit-name>
</persistence-unit-ref>
</session>
</enterprise-beans>
And if I were to employ an interceptor on my Stateless EJB, I could allow Spring to Autowire any addition dependencies of my EJB that might be contained within the Spring context.
@Interceptors(SpringBeanAutowiringInterceptor.class)
So it would seem that at that point, I could perform a JNDI lookup based upon the scoping rules associated to the JEE component which is the EJB.
And incase anyone is still interested in how to get all of this working with the embedded-glassfish-all plugin and Spring, here are the steps.

I hope this will save someone days worth of aggravation and frustration trying to figure out how to get all the pieces working together.
