I forgot a crucial piece of configuration. To use the JNDI persistence
unit in Spring's configs, you must add the following to web.xml :
<persistence-unit-ref>
<persistence-unit-ref-name>persistence/MyPU</persistence-unit-ref-name>
<persistence-unit-name>MyPU</persistence-unit-name>
</persistence-unit-ref>
