You may want to look at Cayenne ORM:

May I ask why you recommend Cayenne instead of the db.apache.org frameworks?
db-ojb has everything (incl paging) that Jini is asking for.
I have no problems if users are pointed to other solutions if there are any limitations in our software that are dealt with in other products.
But I don't see such problems in this case.

1. I have atleast two databases which I wish to communicate with. That requires DB queries crossing between tables or even databases.
Cayenne allows to have multiple databases used transparently. It will figure out where to send each query behind the scenes.
4. As I may have say 10 users at a time logged on each of them returning 2000 rows each = 20,000.
Cayenne has a feature that we successfully used at http://www.nhl.com/ - paginated results, when the list returned is being resolved "lazily" addressing performance and stale data issues:

Hi,
I am looking to write a web application/(servlet/JSP) and I have the following requirements.
2. When selecting rows I may have say 100 rows returned probably over 2000 but I wish to display twenty at a time.
3. With point two I am worried that I may be displaying stale data.
4. As I may have say 10 users at a time logged on each of them returning 2000 rows each = 20,000.
I intend to use struts frame work for session control between users.
Is this db the right framework for me if not which framework is most useful for me ?
