JAXB unmarshalling exception: unexpected element

[freeke625]

Hi

I'm getting a 'JAXB unmarshalling exception: unexpected element' when calling a webservice endpoint from soapUI.
URI & local of the element are OK, the message is validated by a PayloadValidatingInterceptor based on the xsd used to generate classes using xjc - but the service expects a void URI and local element.
Any thoughts on what could be the issue or how to further debug?

Thanks

Frederik

Hi

If you could send some code, I'll try to help.

Hi Grzegorz,

Thanks for the offer
As a bit of background: I'm experimenting with Spring WS to send user id and receive other credentials back.

I'm getting this exception, actual request triggering it is included:

The xsd is the following:

Java classes are generated from this xsd using

xjc -extension

ObjectFactory is present; and package-info class contains annotation to bind to namespace:

@javax.xml.bind.annotation.XmlSchema(namespace = "http://www.test.com/ws/domain/credential", elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)

All generated classes have proper annotations, e.g. for the UserCredentials class:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {

})
@XmlRootElement(name = "UserCredentials")

And my spring xml:

Hi Grzegorz,

I tried to post a couple of replies wih code, but none of them seems to appear. Anything specific I need to do to get them posted?

Hi

Try via github

[freeke625]

I rebuilt the entire thing from scratch, and the error went away.
I must have done something to corrupt the project structure.
Thanks anyways, back to some real work
