I have two Entities

University   
   courses

Course
   students

i want to access all the students in a university. I tried the following query

select u.courses.students from university u

i got the following exception.

org.hibernate.QueryException: illegal attempt to dereference collection [university0_.id.courses] with element property reference [students] [ select u.courses.students from com.socialsite.persistence.University u  ]
    at org.hibernate.hql.ast.tree.DotNode$1.buildIllegalCollectionDereferenceException(DotNode.java:46)
  .....
