[EJB 3.0] - Path expected for join!
by meselfe
Why am i getting this exception:
javax.ejb.EJBException: javax.persistence.PersistenceException: org.hibernate.hql.ast.QuerySyntaxException: Path expected for join! [select p from dk.simpletime.model.entity.Project as p join Task as t where p.id = :projectid]
..when performing the query:
String queryStr = "select p from Project as p join Task as t where p.id = :projectid";
Query query = manager.createQuery(queryStr);
query.setParameter("projectid", projectId);
query.setMaxResults(max);
query.setFirstResult(index);
List tasks = query.getResultList();
Theres a @OneToMany relation from Project to Task.
Can any1 help?
Also what would be the query to select all Tasks given a Project?

[EJB 3.0] - Re: Error loading Embeddable EJB3 in JBoss
by kc_schaefer
I am trying to run the Embeddable EJB3 with IntelliJ IDEA agaist JBoss and I get the same RuntimeException about a writeToDOM signature in xerces. I can understand why the person trying to run this agaist Weblogic would have issues with the xerces version incompatability but I don't see why I would have that issue with JBoss. Any information on why I am getting this exception would be greatly appreciated.
