How to unmarshal a SOAP Fault in a FaultMessageResolver?

Question

I'm new to Spring-WS, and slowly getting my head wrapped around it. Right now, I'm writing a simple client to communicate with an existing WS. I'm using the WebServiceTemplate and the marshalSendAndReceive method. Everything works fine. However, when a SOAP fault occurs, the WST throws a SoapFaultClientException. I noticed that I can create my own FaultMessageResolver to check what is contained within the SOAP fault. However, when I try to unmarshal the WebServiceMessage in my FaultMessageResolver, I get the following error message: ``` JAXB unmarshalling exception; nested exception is javax.xml.bind.UnmarshalException: unexpected element (uri:"http://schemas.xmlsoap.org/soap/envelope/", local:"Fault"). Expected elements are .... ``` Obviously, my unmarshaller is not properly configured. Do I have to generate the JAXB fault model myself using xjc to then be able to unmarshal the error? I am somewhat amazed that this does not already exist. Is there a better way to extra my custom erro…

Accepted Answer

Based on the error you're getting, it looks like you are trying to unmarshall XML source starting with the `` node. Without seeing your Java code, this means you are probably trying to unmarshall the source from `message.getSoapBody().getFault()` You actually need to go deeper to get to the `` node. You should be able to get to this by the following path... maybe not all at once :) ``` message.getSoapBody().getFault().getFaultDetail().getDetailEntries().next() ```
