groovy.lang.MetaClass is an interface, and JAXB can’t handle interfaces

Nope. Sure can’t. And that sucks. But how do I get my Grails domain objects to pass over web services.

I’m SOOOO happy I finally figured this out. It made our web services almost unreadable and unusable.

Anyway, if you are struggling with this, my solution is to use the XML annotation @XmlAccessorType(XmlAccessType.FIELD) in the domain class. This will limit JAXB’s exploration of the object to only the declared members. Awesome.

(remember to “import javax.xml.bind.annotation.*;”)
