@JoinColumn V/s @JoinTable

I can do 1 to many unidrectional mapping
through both @JoinColumn or @JoinTable. whats the difference between two?

Hi Ambar,

Use @JoinColumn when the Entities have direct relationship i.e a foreign key between Entity1 and Entity2.
Use @JoinTable when you manage the relationship between Entities in another table also referred to as JoinTable.

Hope that helps
