i have a select like this:
Query q = em.createQuery("select p from Pais p");
but sometimes, it hangs on q.getResultList(); so i close my app (an rcp app) an open it again. so i open the view that does this select, and then eclipselink says
A signal was attempted before wait() on ConcurrencyManager. This normally means that an attempt was made to
commit or rollback a transaction before it was started, or to rollback a transaction twice.
is it a dedalock?
heres my configs:
EntityManagerFactory: http://pastie.org/1521317
PaisDAO: http://pastie.org/1521318
the GermantechDAO superclass: http://pastie.org/1521319
any ideas?
thx!
