Use interfaces in JAX-WS web methods

Question

I need to use an interface as a parameter and as a return type in a JAX-WS web method. When starting my server I receive an IllegalAnnotationsException, which tells me that JAXB cannot handle interfaces.

I tried to annotate my class, method result and method parameters with @XmlRootElement and @XmlElement(type = ...) respectively, but this does not work.

How can I use an interface as an parameter and as a result type in a JAX-WS web method?

Take a look at @XmlJavaTypeAdapter. Maybe it will do the trick. More information available in here.

Thanks, that worked so far, but it seems a bit complicated for me. Is this the only possible solution? Can you explain why `@XmlElement(type=...)` does not work? – Manuel Faux May 03 '13 at 08:55
@ManuelFaux - Which JAX-WS implementation are you using? – bdoughan May 03 '13 at 09:42
@BlaiseDoughan I use JBoss JAX-WS 2.2 – Manuel Faux May 03 '13 at 10:09
Thanks I solved it with `@XmlJavaTypeAdapter`. But I'm still curious why `@XmlElement` does not work. – Manuel Faux May 04 '13 at 08:38
