hi all,

Please consider the follwoing example
https://glassfish.dev.java.net/javaee5/ ... ample.html

In my scenario consider this onetomany relationship as UniDirectional.

The problem is when i update the customer by removing an order,the entity manger MERGE removes only the link but not the entier row realted that order.i.e., removes the CUSTOMER_ID from the ORDER_TABLE,not the entire row.

For this whether i have use Entity manger.remove while updating???

Is anyone faced the same problem???

regards,
sathish

If you want the entire row on the order table deleted you need to specify cascade for delete orphan.

Here are some info about it.
