mongodb - Appengine + Hibernate OMG - how to make it work? -

i trying simple example running jetty dev server comes eclipse plugin. far no luck.

code:

this code: entitymanagerfactory entitymanagerfactory; entitymanager entitymanager;  entitymanagerfactory = persistence.createentitymanagerfactory( "hike-pu" ); entitymanager=entitymanagerfactory.createentitymanager();  entitymanager.gettransaction().begin();  person p = new person("peter");  entitymanager.persist(p);  hike mountkillmore=new hike("mountkillmore flat", "palm springs"); mountkillmore.organizer=p;   p.organizedhikes.add(mountkillmore);  hike rushduddeldei=new hike("rushdudeldidei down", "rush upstream"); rushduddeldei.organizer=p;   p.organizedhikes.add(rushduddeldei);  entitymanager.persist(p); entitymanager.persist(mountkillmore); entitymanager.persist(rushduddeldei);  entitymanager.gettransaction().commit();  entitymanagerfactory.close(); 

and here error stacktrace getting:

my first guess might running whitelisting issue loaded classes. reason being, exact same code works fine standalone client using same persistence unit, jars.

what think? can somehow overcome this: access denied ("java.lang.runtimepermission") ?
