You need to add schema elements that describe which file should contain the elements of each namespace that you have:
<configuration>
[...]
<schemas>
<schema>
<namespace>http://www.example.invalid/2001/05/27/wibble</namespace>
<file>wibble.xsd</file>
</schema>
</schemas>
<configuration>
Assuming you created your component namespace
@XmlRootElement(name = "wobble", namespace="http://www.example.invalid/2001/05/27/wibble")
