Subject: Multiple database updating - Entity Bean


Hi all,

I have the following situation.

I have a stateful session bean which handle the customer common data
throughout his session.
In that I am implementing setDetails(), getDetails() and modifyDetails()
functions.

setDetails() calls the stateless session bean method to get the result set.

getDetails() function simply returns the result set to Servlet/JSP.

Now, the main question is - in modifyDetails() function -->

        I am planning to use entity bean for my modification function.

        1) I want to pass the query String for updations.
        2) Can I do multiple table updations in one query?
        3) if I pass query string to modifyDetails() function, How I know
about primary keys?
        4) without the knowledge of PKs, how can I identify the proper
entity bean?

Can anybody please suggest me the solution for the third function
(modifyDetails())
Is entity bean is better, or Are there any options for this?
We want database updation immediately, and from next screen onwards the new
values should come to screens.

Thanks in advance,
