The related persist classes are: // ------ The class with @OrderBy annotation @Entity @Table(name="RG_SECTION") @IdClass(SectionID.class) public class Section extends AbstractSection{ @ManyToMany(fetch=FetchType.EAGER) @JoinTable(name="V_Current_Section_Term", joinColumns= { @JoinColumn(name="Section_School_Id", referencedColumnName="School_Id"), @JoinColumn(name="Section_ID", referencedColumnName="Section_ID")}, inverseJoinColumns= { @JoinColumn(name="Term_School_Id", referencedColumnName="School_Id"), @JoinColumn(name="Term_Academic_Yr", referencedColumnName="Academic_Yr"), @JoinColumn(name="Term_Sort_No",referencedColumnName="Term_Sort_No")} ) @OrderBy("termSortNo") public List<Term> getTerms() { return super.getTerms(); } // -------------- This Entity class in the Collection --------- @Entity @Table(name="SCHOOL_TERMS") @IdClass(TermID.class) public class Term extends AbstractBusinessObject implements Comparable{ ....
