Mapping ResultSet to Context and vice versa

Question

Hi,
We've been pondering the usage of SQL ResultSet (java.sql.ResultSet) and the context.
When creating database applications we have to get the data from database to a ResultSet and copy the data to the context to be able to use it. Then if we make changes to the data in the context, and have the same changes in the database, we have to create SQL update clauses for the data in the context and execute them. With ResultSet it would be just:
rs.updateString("NAME", "AINSWORTH"); // updates the name
rs.updateRow(); // updates the row in the datasource
We would like to use ResultSets for the data behind controls (tables etc.) to be able to update the resultset and the database without having to write SQL update, insert, delete etc. clauses.
Is this possible ? If it is, how ? If it is not, why ?
Any insight or suggestions are greatly appreciated.
Kind Regards,
Jari Pakarinen

Thanks for the reply,
Web service would just add complexity, as we are aiming for simplicity. Also we would like to lessen the amount of boilerplate code to do this. Now we have to create SQL clauses for everything we do with the database. And this for every application we code.
If we could use ResultSet instead of Context or somehow map Context and ResultSet dynamically as the data source for the controls we'd be all set.
We would like to just load the data into a ResultSet, do modifications to it WITHOUT SQL (with e.g. WebDynPro table) and commit the modifications WITHOUT SQL back to the database. Only SQL needed would be the one that loads the ResultSet in the first place.
