Yes. you can use Spring as your middleware and take full advantage of Seam
managed persistence contexts without seam or Spring being non the wiser. The
documentation details how you can use Seam Managed persistence contexts with
spring and how you can use Spring managed transactions with
updated the docs to include a note about the jboss-seam-ioc dependency.
