According to SOAP specs v1.1 Section 6.2(http://www.w3.org/TR/2000/NOTE-SOAP-20000508/#_Toc478383529) and v1.2 Part 2 Section 188.8.131.52(http://www.w3.org/TR/2007/REC-soap12-part2-20070427/#http-reqbindwaitstate), all 2xx HTTP status codes are successful responses.
In the case of SOAP v1.2, the spec even goes so far as to state "The SOAP HTTP binding follows the rules of any HTTP application which means that an implementation of the SOAP HTTP binding must understand the class of any status code, as indicated by the first digit, and treat any unrecognized response as being equivalent to the x00 status code of that class, with the exception that an unrecognized response must not be cached."
Given that, an HTTP status code of 201 (Created) in response to a SOAP request currently throws an error. The 201 is just an example, as any 2xx status code other than 200 and 202 will also throw an error. The problem is in org.apache.axis2.transport.http.HTTPSender.handleResponse(MessageContext, HttpMethodBase) where all status codes that are not explicitly handled are treated as an error. After reading the spec, it looks like those unhandled 2xx status codes should be handled the same as 200. Therefore, I am attaching a patch that treats all 2xx status codes other than 202 as a 200 response.
Revised handling should probably be considered for other status code classes/families as well. However, since those are error conditions anyway, they will probably have a much lesser impact.
