Hi--
To follow up, here is the current generic account bean that I am trying to
setup according to the DTO and facade patterns. CMR is with another address
bean that also has value objects associated, as well:

Sorry - should have included this info in the original post... :(

Subject: [Xdoclet-user] ejb.facade and valueobjects
Hi--
I am currently switching the design of my app from using xdoclet dataobjects
with homemade entity facades to valueobjects and the xdoclet-gen'd facades.
Specifically, I thought that the value objects from xdoclet would greatly
help in updating/adding/removing the n (many) side of cmr.
I am wondering if someone could provide some enlightenment on the usage of
the entity facade from xdoclet.
I saw in the online docs that valueobject elements are to replace the
deprecated dataobjects elements. Seeing this, I assumed I should someday
stop generating dataobjects altogether?
With the deprecation of dataobjects, I had also assumed that the facades
would probably generate methods to return value objects, but I see that
dataobjects are primarily the return references. Data objects have
references to value objects, so should I get the dataobject from the facade,
then get the value object from the data object in order to set or update
properties, including the 1-n cmr objects? I don't see an update/set
methods on the facade that take either data or value objects and,
presumably, update the persistant data store.
As you can see, I am hoping to maintain the cmr fields that I have and
switch to using value object and the xdoclet facade. However, I just do not
yet understand how I can provide updates to the entity and cmr entities
using the provided pattern. Can anyone provide some client code or a means
for gaining this understanding?
Thank you very much!
Matt Hanson
