I have problem with composite primary key and Foreign key having the same column.

Example

Table A PK (ID , NEW_ID)

Table B PK (ID, NEW_ID) FK (A_ID, NEW_ID)

when I used the below way in the child B when referring A

@ManyToOne
@JoinColumns({@JoinColumn(name = "A_ID", referencedColumnName = "ID"),
@JoinColumn(name = "NEW_ID", referencedColumnName = "NEW_ID")})
When I try to save B. I am getting an error of invalid Index.

So I am guessing it was also trying to set NEW_ID two times and getting this error.

I have no option to set one column as insertable and updatable as false.

Can any one help me in this

I think there is a mistake in your many to one definition
you need to give the class name too like :

@ManyToOne(targetEntity = A.class)
@JoinColumns({@JoinColumn(name = "A_ID", referencedColumnName = "ID"),
@JoinColumn(name = "NEW_ID", referencedColumnName = "NEW_ID")})
