Hi,
perhaps it is a dumb question; but it has taken a lot of time and I still have
not found a solution.
I want to get all courses for a instructor in my EJB.
| public List<Course> getCoursesForInstructor(CmtUser instructor){
| try{
|
| String id = instructor.getId().toString();
| //Long id = instructor.getId();
| Query q = em.createQuery(
| "SELECT c FROM Course c" +
| " WHERE c.instructor = :instrId");
| q.setParameter("instrId",id);
|
| List<Course> courses = (List<Course>) q.getResultList();
| return courses ;
| }
| ...
If I type:
WHERE c.instructor = 2
it is no problem.
But if I set the parameter with:
q.setParameter("instrId",id); I get an
IllegalArgumentException ...
| ...org.hibernate.PropertyAccessException: could not get a field value by
reflection getter of de.cmt.model.CmtUser.id)
Any ideas?
Thanks Nicki
