I generally do it all manually as I tend to need to either do additional
validation or slightly change what's put into the database.
However, if you have all of the same form and ObjEntity field names, you
could do it in a loop.
I think you can use DynaActionForm.getMap() to get all values for the form
and iterate through them.
You could then use DataObject.writeProperty("key", value) to set them on
your data object.
Keep in mind that a DynaForm only stores Boolean and String values, so your
DataObject could only have those two data types.
I've never used BeanUtils, and I don't know if it's flexible enough to
provide a generic interface to a DataObject.
I suspect worse case you could probably define a "set(key, value)" method
for your DataObject (or whatever it expects) and make it work, though.
