Hibernate @OneToOne Mapping

I have following piece of code..

  1. working fine (staffTbl is not getting fetch lazily) @OneToOne(fetch=FetchType.LAZY) @JoinColumns({@javax.persistence.JoinColumn(name="inst_id", referencedColumnName="inst_id", insertable=false, updatable=false), @javax.persistence.JoinColumn(name="staff_id", referencedColumnName="staff_id", insertable=false, updatable=false)}) private StaffTbl staffTbl;

  2. but when I made this transient its always fetching null: @OneToOne(fetch=FetchType.LAZY) @JoinColumns({@javax.persistence.JoinColumn(name="inst_id", referencedColumnName="inst_id", insertable=false, updatable=false), @javax.persistence.JoinColumn(name="staff_id", referencedColumnName="staff_id", insertable=false, updatable=false)}) private transient StaffTbl staffTbl;

Is there any mistake?

(I'm using Hibernate 3, with JBoss 6.1)

Solution

  • Is there any mistake?

    if a field has marked as transient, it means they are not part of the persistent state of the entity.

    Solution:

    change to:

    private StaffTbl staffTbl;
