BMP - findByPrimaryKey

[Ranganathan Kaliyur Mannar]

Hello,
I tested a BMP entity bean on JBoss server. While calling the findByPrimaryKey method on the bean, I got the following sequence(through SOPs) :

1.setEntityContext
2.ejbFindByPrimaryKey
3.setEntityContext
4.ejbActivate
5.ejbLoad
6.ejbStore
7.ejbStore

steps 1-5 are clear. But why is ejbStore called when all I want to is to read the record? is it implementation-specific(eg.JBoss)?

Thanks,
Ranga.
