JAXB Unmarshalling Error，没有命名空间的package-info文件？

Question

I am attempting to Unmarshall XML from a file using JAXB. I also have a web service. I want to use no namespace, not the namespace defined by the web service.

I am getting the following error:

Exception in thread "main" javax.xml.bind.UnmarshalException: unexpected element (uri:"", local:"CustomerName"). Expected elements are <{http://www.ws.NET}CustomerName>

I think that the solution is to change the package-info.java file to use no namespace. Is this the correct approach? and what changes should I make to this file? The package-info.java file looks as follows:

@javax.xml.bind.annotation.XmlSchema(namespace = "http://www.ws.NET", elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package mynewpackage;

Thanks for your help

Answer 1

Changing QUALIFIED to UNQUALIFIED will help if the top-level element (corresponding to the @XmlRootElement annotated class) is in the target namespace but its children aren't, eg

<ns:Response xmlns:ns="http://www.ws.NET">
  <CustomerName>Ian</CustomerName>
</ns:Response>

but this won't help if the top level (in this case Response ) element is also unqualified.

Answer 2

When you have a JAXB model that is annotated to be namespace qualified and you want to unmarshal XML that isn't there are a couple of options.

If You Can Change the Model

You may just need to remove the @XmlSchema annotation from the package-info class. If there are no other package level annotations you could remove the whole class. Note that namespace information may also be specified on other annotations such as @XmlElement .

If You Can't Change The Model

If you can't change the JAXB model to remove the namespace qualification then you can leverage a SAX XMLFilter to apply a namespace to the XML as it's being read.
