Versioning of Web Services using Interfaces
We have deployed CXF throughout our organization with a great degree of
success. That being said, we've not done a very good job of versioning any
of our services. We've been stuck on version 1.0.0 of all of our services
(making changes to the xsds and wsdls), forcing our clients to rebuild
before deploying a new release. This isn't ideal.
That being said, I'd like to create a pure POJO service layer that my web
services delegate to without passing in the JAXB generated Request objects.
Ideally, I would like my JAXB Request objects to implement an interface that
my POJO service tier could use. I was wondering if anyone can point me to
some good documentation on how to achieve this.
Thanks,
John

Maybe the following document gives you some ideas:

IMHO, I'd have an unversioned business logic layer where you have versioned jaxb classes where you semantically adapt the jaxb classes to your business logic layer which is decoupled from the communication technology.
Thanks
Oliver

Using interfaces with JAXB can be quite difficult. For each interface, you
need to create the concrete implementations (which get output to the WSDL) as
well as type mappers that would bind the two together. Then various
@XmlSeeAlso's and @XmlJavaTypeAdapter things, etc....
As a starting point, look at the java_first_jaxws sample in the distro. It
shows using an interface for an web method.
