Hi ,
I did a One to Many example in Hibernate .
I took a Student Pojo , and a Address POJO .
Assuming the scenario as
(A Student can have many Addresses)

If i use the option as inverse = true on to the Set tag of my Student hbm file , it works fine

But if i dont use this attribute On to the Set tag , it throws an Exception as ConstraintViolationException .

I heard that we use inverse attribute to make it bidirectional .

Please share your ideas why is it happening

(Its only a Unidirectioanl relation between two POJOs only at the Java level )
