In the documentation, the HTTP request parameters can be fetched if you use an http-gateway. (Unfortunately, there ws no similar documentation for jbr-provider.) I have a requirement to serve up a SOAP endpoint (with wsdl), so I do not believe http-gateway is an option.
I looked at the jbossesb-4.8 src over the weekend.
The SOAPProcessor class creates an instance of SOAPProcessorHttpServletRequest. This class defines this method.
public String getRemoteAddr()
throw new UnsupportedOperationException("Not yet supported") ;
Unless anyone can say differently, it appears the HTTP Request parameters are not available if you use jbr-provider and action SOAPProcessor.
Of course, documentation shows http-gateway will provide the information I am looking for...but I have not figured out how to generate WSDL using http-gateway.
