Refetching
Other capabilities include refetching beans. By refetching we mean that the values in the context are re-read and the state of the bean is updated. Since the bean session manages instances of beans, every effected bean would show changes seamlessly.

//.. assuming that a bean session exists and you have the subject of the bean
Person person = (Person) beanSession.fetch(subject);
// if some other process updates the context and you need these changes
beanSession.refetch(subject);
// now the stated person as well as any other beans it references, reflects these changes. |
