org.apache.cxf.interceptor.Fault: Marshalling Error: ELEMENT_NAME_MISMATCH

Question

I am new to apache cxf. I was using a cxf Interceptor to intercept my soap response and send a custom fault mesaage. Everything works fine when i try from Soap UI. But when i run tests , i get the correct response followed by this error "org.apache.cxf.interceptor.Fault: Marshalling Error: ELEMENT_NAME_MISMATCH" due to which tests failed.

Error (The Weird thing is i get the soap response back before this error gets thrown)

Answer 1

Finally figured out the error. Its because my test client wasn't able unmarshall the response properly due to mismatch in the QName. I was following a code first approach, so had to manually create a "package-info.java" like this and mention my Qname.

@javax.xml.bind.annotation.XmlSchema(namespace = "www.example.com/common/exceptions", elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package com.example.common.exceptions;
