title: RESTful WebService Schema Validation
body: <p>I was going through the Jersey doc and found that the marshalling and unmarshalling happens
  automatically using the JAXB annotation @XmlRootElement. My question here is how to impose
  the schema (xsd) validation before the unmarshalling  process to get rid of any xml request errors.Any example of how validation works would be really great.</p>
  
  <p>Thanks,
