Hi All, One of the received messages fell over when the following attribute was present in the soap message:
<soap:Header> <CustomAttr soap:mustUnderstand="1" > <soap:Header> [Thu Oct 28 15:31:23 2010] [debug] apache2_worker.c(299) Client HTTP version HTTP/1.1 [Thu Oct 28 15:31:23 2010] [debug] soap_builder.c(883) Identified soap version is soap11 [Thu Oct 28 15:31:23 2010] [debug] phase.c(202) Invoke the handler request_uri_based_dispatcher within the phase Transport [Thu Oct 28 15:31:23 2010] [debug] req_uri_disp.c(97) Checking for service using target endpoint address : http://abc.def/axis2/services/ReceiveMessageAsync/ [Thu Oct 28 15:31:23 2010] [debug] req_uri_disp.c(117) Service found using target endpoint address [Thu Oct 28 15:31:23 2010] [debug] req_uri_disp.c(172) Checking for operation using target endpoint uri fragment : [Thu Oct 28 15:31:23 2010] [debug] phase.c(202) Invoke the handler addressing_based_dispatcher within the phase Transport [Thu Oct 28 15:31:23 2010] [debug] phase.c(202) Invoke the handler rest_dispatcher within the phase Dispatch [Thu Oct 28 15:31:23 2010] [debug] phase.c(202) Invoke the handler soap_message_body_based_dispatcher within the phase Dispatch [Thu Oct 28 15:31:23 2010] [debug] soap_body_disp.c(200) Checking for operation using SOAP messagebody's first child's local name : Request [Thu Oct 28 15:31:23 2010] [debug] phase.c(202) Invoke the handler soap_action_based_dispatcher within the phase Dispatch [Thu Oct 28 15:31:23 2010] [debug] soap_action_disp.c(108) Checking for operation using SOAPAction : http://htng.org/1.1/Listener.Wsdl#ReceiveMessageAsync [Thu Oct 28 15:31:23 2010] [debug] soap_action_disp.c(139) Operation found using SOAPAction [Thu Oct 28 15:31:23 2010] [debug] phase.c(202) Invoke the handler dispatch_post_conditions_evaluator within the phase PostDispatch [Thu Oct 28 15:31:23 2010] [debug] phase.c(202) Invoke the handler context_handler within the phase PostDispatch [Thu Oct 28 15:31:23 2010] [error] engine.c(806) Must understand soap fault occured [Thu Oct 28 15:31:23 2010] [error] engine.c(283) Check for must understand headers failed As a work around , i have changed , the following: ./axiom/include/axiom_soap_const.h:#define AXIOM_SOAP_ATTR_MUST_UNDERSTAND "mustUnderstand" to ./axiom/include/axiom_soap_const.h:#define AXIOM_SOAP_ATTR_MUST_UNDERSTAND "soap:mustUnderstand" As i understand , the same is just prefixed with name space soap and should not fail.... any thoughts ? Cheers!
