hi andrius,
Thanks for your ideas. I have some follow up questions if you have the time.

yes, I'm aware that EJBDoclet automatically generates the dataholder
classes. Didn't realize this was integrated with the Webwork front end,
but I guess that makes sense considering that Rickard is the author of both.

I'm doing something similar - I created a generic data object that I call
ListItemData that contains 4 properties: primKeyStr (string version of a
primary key), name (that contains the name to display with an href link on
a web page or other list, e.g. Swing list), description (containing a
longer string to display...optional), and ejbname. I'm planning to create
1 or perhaps multiple session beans that provide finder-like methods to
return a collection of ListItemData objects to the client. These objects
are then used to generate a list output to the user. If the user selects
one, the ejbname and primKeyStr are used to generate a call to the
appropriate Entity EJB for display/update/delete.
Question: how do you see your idea solving the 1->n relationship
problem? I don't follow...
Thanks again,
Rick
