> Here I like to talk about the options to support
> org.apache.axiom.om.OMElement datatype in our databinding scope....
> Since OMElement is an interface, the JAXB runtime throws the following
> exception....
> org.apache.axiom.om.OMElement is an interface, and JAXB can't handle
> interfaces.
> this problem is related to the following location:
> at org.apache.axiom.om.OMElement
> at protected org.apache.axiom.om.OMElement
> org.apache.tuscany.sca.binding.ws.axis2.itests.mtom.jaxws.UploadOMElementFile.arg0
> at
> org.apache.tuscany.sca.binding.ws.axis2.itests.mtom.jaxws.UploadOMElementFile
> JAXB recommends to use an XMLAdapter to solve this issue, by creating an
> XMLAdapter for your interfaces (OMElement) and by using
> @XmlJavaTypeAdapter in the service method as shown below.
> @XmlJavaTypeAdapter(value=OMElementXmlAdapter.class, type=OMElement.class)
> public String uploadOMElementFile(OMElement attachment) throws Exception;
> Using @XmlJavaTypeAdapter in the service method, throws the following
> exception.....
> java.lang.IllegalArgumentException: value class
