Persist JPA Entity to a file system

[redbull]

Is there a way to persist a EJB3 entity to a flat or xml file to test
an application if you don't hava a database at hand?

I thought I have read something about it lately but I (google) can't
find it.

Will ordinary serialization work?

You can always use derby or hsqldb to test the code.
