"Online Information"

Exception: Associations marked as Mappedby must not define database mappings like @JoinTable or @JoinColumn
The error occurs in the following code
@OneToMany (mappedby= "parent", Fetch=fetchtype.eager,cascade=cascadetype.all)
@JoinColumn (name= "parent_id")
Private list<category> child = new arraylist<category> ();
Later found in 3.5.3 Release @joincolumn and Mappingby are mutually exclusive, before in hibernate.3.3.2 is correct, that is, hibernate.3.3.2 allow the two to exist.
So, if the upgrade to hibernate3.5.3 want to test success, mappby= "parent", should be removed, the correct configuration should be
@OneToMany (Fetch=fetchtype.eager,cascade=cascadetype.all)
@JoinColumn (name= "parent_id")
Private list<category> child = new arraylist<category> ();
