WebFaultOutInterceptor expects the Fault.
-----------------------------------------
Key: CXF-3925
URL: https://issues.apache.org/jira/browse/CXF-3925
Project: CXF
Issue Type: Bug
Components: JAX-WS Runtime
Affects Versions: 2.4.4
Reporter: Michał Mech
WebFaultOutInterceptor reports NullPointerException when message content
doesn't contains Exception.
I was trying to create custom interceptor to transform SoapFault to SoapMessage
([read
more|http://stackoverflow.com/questions/8066474/how-to-transform-soapfault-to-soapmessage-via-interceptor-in-cxf])
and when I registered interceptor like:
{code:title=InternalActServiceFaultOutInterceptor.java|borderStyle=solid}
public class InternalActServiceFaultOutInterceptor extends
AbstractSoapInterceptor {
public InternalActServiceFaultOutInterceptor() {
super(Phase.PRE_STREAM);
addBefore(Arrays.asList(StaxOutInterceptor.class.getName(),
AttachmentOutInterceptor.class.getName()));
}
@Override
public void handleMessage(SoapMessage soapMessage) throws Fault {
Exception exception = soapMessage.getContent(Exception.class);
if (exception != null) {
soapMessage.getExchange().put(Exception.class, null);
for (Class<?> contentFormat :
soapMessage.getContentFormats()) {
soapMessage.setContent(contentFormat, null);
}
soapMessage.setContent(List.class, new
MessageContentsList(createSoapMessage(RegisterDocumentResponse.class)));
}
}
private <T> RegisterDocumentResponse createSoapMessage(Class<T>
messageType) {
RegisterDocumentResponse response = new
RegisterDocumentResponse();
response.setStatus(ServiceStatusType.SUCCESS);
return response;
}
}
{code}
I saw:

It's all because WebFaultOutInterceptor expecting in line 83 Fault in message.
