XSnapshot is a module for XDoclet similar to the @ejb.value-object tags
but much more flexible. It creates DTOs from "snapshots" of a POJO
domain model, so it works with Hibernate and is not coupled to EJB.
The original purpose of XSnapshot is to make it easier to pass
Hibernate-persisted POJOs around with a remoting framework like Hessian,
AJAX/DWR or Axis. But it's also extremely useful for generating
POJO-bound Struts ActionForms as well. The value over the current
@struts.form tag is its ability to handle relationship-to-ID conversion
and vice versa. If you want to add a new many-to-one relationship to a
POJO data class, and a corresponding <select> widget in a JSP, you only
have to touch those two files. You don't have to add a special case for
"Bar b = BarManager.getBar(form.getBarId()); foo.setBar(b)" to your
Action.
XSnapshot is available at xsnapshot.sf.net. The example application
shows how to use XSnapshot with Hibernate and Struts. Documentation is
very thin now but more should be coming soon. I hope you will find it
useful!
Cheers,
Bill
