StatelessEJBProvider bug
Hi:
I played around the source code of StatelessEJBProvider and found out there
is a problem in the invoke() method of StatelessEJBProvider, when preparing
the response, the encoding style it is picking up is
call.getEncodingStyleURI() which gives back null if the request has the
encoding style in the envelop instead of body.
I also found there is a variable respEncStyle defined and assigned values in
the class but never used. It looks like here it should use respEncStyle
instead of call.getEncodingStyleURI().
AFter I changed it, then it works.
I am using the apache SOAP 2.1 release, has this been fixed?
Thanks
Jian
try {
System.err.println("response encoding style is
"+call.getEncodingStyleURI());
Response resp = new Response( targetObjectURI, // URI
call.getMethodName(), // Method
(Parameter) ret, // ReturnValue
null, // Params
null, // Header
// call.getEncodingStyleURI (),// encoding
respEncStyle,
resContext ); // response soapcontext
- not supported yet
Envelope env = resp.buildEnvelope();
StringWriter sw = new StringWriter();
env.marshall( sw, call.getSOAPMappingRegistry(),
resContext );
resContext.setRootPart( sw.toString(),
Constants.HEADERVAL_CONTENT_TYPE_UTF8);
}
