There is JSF groovy support that enables you writing JSF components and
managed beans in groovy. See Ryan's blog[1] that details the approach.
Here he is using a servlet filter to process the groovy scripts, under
the hood it uses GroovyScriptEngine to interpret the groovy scripts.
I am not sure but you can try by creating GroovyScriptEngine[2] with the
thread contextClassLoader frm inside the filter and write your own
classloader that is used to load the Persistence class and create
EntityManager from it. Mitesh or someone from JPA team can confirm this
approach but I think this should work.
I would like to know how it goes...
