I have a queer problem . I have an CMP Entity Bean which inserts (Person) details and the Primary Key is a sequence triggered by the database .
My Client program works fine and does inserts rows but fails in certain predictable cases with Duplicate Key Exception
when the previous bean instance is not passivated (I hope my inference is correct ) .
This happens when I run my client Program repeatedly . My primary key is an integer. I have a PK class and so a pk (personid )instance variable in the fields
Below is the server side log . where I have 2 successful inserts and a Duplicate Key exception .

I would like any input regarding this . I am not sure my inference is the correct reasoning behind this .
Thanks
