I am encountering this following CXF exception:
warning: Interceptor for {http://example.com/wsdl/esc/2011-12-12/}AmazonEC2#{http://example.com/wsdl/esc/2011-12-12/}NewDescribeImages has thrown exception, unwinding now

javax.xml.ws.soap.SOAPFaultException: Fault string, and possibly fault code, not set
the code that causes this exception:
MyService ms =new MyService ();
MyServicePort port = ms.getAmazonEC2Port();
BindingProvider bp = (BindingProvider) port;
bp.getRequestContext()
.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,
"http://192.180.33.12:8773/services/myservice_url/");
Client client = ClientProxy.getClient(portType);
client.getInInterceptors().add(new LoggingInInterceptor());
client.getOutInterceptors().add(new LoggingOutInterceptor());
Endpoint endpoint = client.getEndpoint();
Map<String, Object> inProps=new HashMap<String, Object>();
Map<String,Object> outProps = new HashMap<String,Object>();
configWSProps(inProps, outProps); //here is some WS-Security properties
WSS4JInInterceptor wssIn = new WSS4JInInterceptor(inProps);
WSS4JOutInterceptor wssOut = new WSS4JOutInterceptor(outProps);
endpoint.getInInterceptors().add(wssIn);
endpoint.getOutInterceptors().add(wssOut);
SomeResponseType response = port.someMethod();
This exception is thrown in the last line: port.someMethod(). In the configWSProps(...) method I set some WS-Security properties, it is not likely to have problem here.
I printed the cxf logs, i can see that the inbound message has the correct data.
From the CXF source code, it seems that CXF fails to retrieve the soap message, but I don't know how to solve this. Please help me!
here is the CXF source code: http://grepcode.com/file/repo1.maven.org/maven2/org.apache.cxf/cxf-rt-bindings-soap/2.4.1/org/apache/cxf/binding/soap/interceptor/StartBodyInterceptor.java/#59
After debugging in the cxf code and seeking help in the cxf mailing list, I finally solved this problem. The problem is caused by the inbound message, the http message lacks the content-type header, which causes the CXF fail to create an XMLStreamReader, and then failed to read the content, thus a NullPointerException is thrown. Many thanks to the guys in the CXF community!
