Immediate help needed please.

I want to select list of composite element

In main object 'A' I have

/**
* @hibernate.list
* table="tab_b"
* @hibernate.collection-composite-element
* class="com.db.B"
* @hibernate.collection-index
* column="idx"
* @hibernate.collection-key
* column="b_id"
*/

Now I am trying simply
"SELECT b from A a LEFT JOIN a.B b where a.id=?"
But It does not works.

javax.servlet.ServletException: could not resolve property: id of: com.db.B

Then I try for

"SELECT new com.db.B( b.lessAmount, b.lessString, "
+ " sllBill ) "
+ " FROM A a LEFT JOIN a.B b "
+ " LEFT JOIN a.bill sllBill "
+ " WHERE a.id = ? ";

But Same problem
javax.servlet.ServletException: could not resolve property: id of: com.db.B

"SELECT new com.db.B( b.lessAmount, b.lessString, "
+ " b.bill ) "
+ " FROM A a LEFT JOIN a.B b "
+ " WHERE a.id = ? ";

It gives no error but give empty list

What should be the way?

Please help me
