Hi Nikolaos,
What Frank is saying is you don't have to go through Stripersist to get
an EntityManager. The main purpose of Stripersist is to provide the
Formatter/TypeConverter for Stripes to handle entities. It also provides
a little security by beginning a transaction so that you must explicity
commit for changes to occur.
I don't use Spring but I'm sure there is some way to get an
EntityManager from Spring without going through Stripersist.
