Composite primary keys

[epbernard]

mappedBy = "rolProceso" => mappedBy = "proceso"

i have a similar error, but no such mappedBy error.

i have defined the fetchtype as lazy and i get this error when i try to get the value of isEmpty or iterator.

the object is detatched. In fact it is serialized out through the local interface. i had initialized the collection data member to an empty array list, but i still get this error. How can i initialize this collection before returning? Please note i do not want to populate the collection yet with all its actual entries.

i am using jboss with ejb3, but i do not have spring framework. i have seen some postings regarding OpenSessionInViewFilter to be added to web.xml.

do i have to do that?

either

@OneToMany(fetch=FetchType.EAGER)

or

UserTransaction trans = (UserTransaction) ctx.lookup("java:comp/UserTransaction");
trans.begin();

[...]
entityManager.createQuery("FROM RolProceso").getResultList();
[...]

trans.commit();
