>
> The CmpJpaConversion code enables TomEE to run CMP entity beans by converting
> them to JPA "on the fly". It does this by using a persistence unit it creates
> on the app module named "cmp", and generating an orm.xml file for the
> persistence component to use.
>
> However, if you create a persistence.xml file and a custom orm.xml file
> (using the `openejb.descriptors.output=true` system property, for example)
> and reference the custom orm.xml in persistence.xml, it is ignored.
>
> One possible workaround is to remove the mapping file reference from
> persistence.xml and package it in the artifact as
> META-INF/openejb-cmp-orm.xml (or WEB-INF/openejb-cmp-orm.xml for .war files):
> [https://github.com/apache/tomee/blob/0165264d37f9cb6ce6d2585f2f6b0fbd926ad5c4/container/openejb-core/src/main/java/org/apache/openejb/config/ReadDescriptors.java#L553]

>
> However, it should be possible to also check for the presence of an existing
> mapping file on the cmp persistence unit, and use that as opposed to
> generating a new one.
