No reason to be sorry. The traditional approach you pointed is a PITA.
I am just mentioning alternatives.

I always read good thinking about WebObjects. I am really getting
curious about it.

UAU! Good performance too?
I did read a lot about its productivity but nothing about
performance.

Yes, but I think javabeans should be reserved for complex business
logic where it shines on the clean & easy aspects.
For data transport a lot can be automated in Java using approaches
like the Dynabeans. I mean, code like this:
bean1.field1 = someOtherSource.getObject("field1");
bean1.field2 = someOtherSource.getObject("field2");
...
bean1.field47 = someOtherSource.getObject("field47");
is really dumb and painful.

A lot of interesting discussions go on OT all the time.
