Take a look at the
http://jaxbvalidation.dev.java.net project. It does exactly
what you need. There's an add-on that generates object validators which can be
used instead of XML-style validation.
User guide is in process, take a look at sample projects instead:
https://jaxbvalidation.dev.java.net/nonav/repository/org/jvnet/jaxbvalidation/jaxbvalidation-sample/1.0.4/jaxbvalidation-sample-1.0.4-src.zip
https://jaxbvalidation.dev.java.net/nonav/repository/org/jvnet/jaxbvalidation/jaxbvalidation-sample-ant/1.0.4/jaxbvalidation-sample-ant-1.0.4-src.zip
Bye.
