To meet project requirements, the axis2 client must be able to process the soap fault returned by the server. However, it is found that axis2 has a problem with soapfault processing.
First, (1) Specify the format of the soapfault message received by the axis2 engine: HTTP/1.1 500 Internal Server Error Service: gsoap/2.7 Content-Type: text/XML; charset = UTF-8 Content-Length: 1916 Connection: Close <? XML version = "1.0" encoding = "UTF-8"?>
<SOAP-ENV: envelope xmlns: SOAP-ENV = "http://schemas.xmlsoap.org/soap/envelope/" xmlns: SOAP-ENC = "http://schemas.xmlsoap.org/soap/encoding/" xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" xmlns: XSD = "http://www.w3.org/2001/XMLSchema" xmlns: wsu = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-
SOAP-ENV: Body>
SOAP-ENV: Fault>
<Faultcode> SOAP-ENV: server </faultcode>
<Faultstring> the value of structure ns__ register is null </faultstring>

(2) encapsulate the soapfault message in axis2 to Code As follows:
Org. Apache. axis2.clientapi. outmepclient. Java
..... Public messagecontext invokeblocking (operationdescription axisop,
Final messagecontext msgctx)
Throws axisfault {
Prepareinvocation (axisop, msgctx ); // The Message ID is sent all the time
String messageid = string. valueof (system. currenttimemillis ());
Msgctx. setmessageid (messageid );
//
If (useseparatelistener ){
// This mean doing a request-response invocation using two channel. If
// Transport is two way transport (e.g. http) only one channel is used (e.g. In HTTP Cases
// 202 OK is sent to Say No repsone avalible). axis2 get blocked return when the response is avalible. Synccallback callback = new synccallback ();
// This method call two channel Non blocking method to do the work and wait on the callbck
Invokenonblocking (axisop, msgctx, callback );
Long Index = timeoutinmilliseconds/100;
While (! Callback. iscomplete ()){
// Wait till the reponse arrives
If (index --> = 0 ){
Try {
Thread. Sleep (100 );
} Catch (interruptedexception e ){
Throw new axisfault (E );
}
} Else {
Throw new axisfault (messages. getmessage ("responsetimeout "));
}
}
// Process the resule of the invocation
If (callback. envelope! = NULL ){
Messagecontext resmsgctx =
New messagecontext (servicecontext. getenginecontext ());
Resmsgctx. setenvelope (callback. envelope );
Return resmsgctx;
} Else {
If (callback. Error instanceof axisfault ){
Throw (axisfault) callback. error;
} Else {
Throw new axisfault (callback. Error );
}
}
} Else {
// This is the usual request-response sync Implemetation
Msgctx. setto ();
Msgctx. setservicecontext (servicecontext );
Configurationcontext syscontext = servicecontext. getenginecontext ();
Msgctx. setconfigurationcontext (syscontext ); Checktransport (msgctx ); // Find and set the operation Context
Configurationcontext syscontext = servicecontext. getenginecontext ();
Axisconfiguration registry = syscontext. getaxisconfiguration ();
Msgctx. setoperationcontext (operationcontextfactory. createoperationcontext (wsdlconstants. mep_constant_in_out,
Axisop,
Servicecontext ));
// Send the SOAP message and receive a response
Messagecontext response =
Twowaytransportbasedsender. Send (msgctx, listenertransport ); // Check for a fault and return the result
Soapenvelope resenvelope = response. getenvelope ();
If (resenvelope. getbody (). hasfault ()){
Soapfault = resenvelope. getbody (). getfault ();
Exception EX = soapfault. getexception (); If (isexceptiontobethrownonsoapfault ){
// Does the soapfault has a detail element for excpetion
If (ex! = NULL ){
Throw new axisfault (Ex );
} Else {
// If detail element not present create a new exception from the detail
String message = ""; message = message + "code =" + soapfault. getcode () = NULL? "":
soapfault. getcode (). getvalue () = NULL? "": Soapfault. getcode (). getvalue (). gettext ();
Message = message + "reason =" + soapfault. getreason () = NULL? "":
Soapfault. getreason (). getsoaptext () = NULL? "": Soapfault. getreason (). getsoaptext (). gettext (); System. Out. println ("message" + message );
Throw new axisfault (Message );
}
}
}
Return response;
}
} .....
Should be changed
Message = message + "code =" + (soapfault. getcode () = NULL? "":
Soapfault. getcode (). getvalue () = NULL? "": Soapfault. getcode (). getvalue (). gettext ());
System. Out. println ("" + message );
Iterator T = soapfault. getdetail (). getalldetailentries ();
Loop (T, 1 );
Org. Apache. axis2.soap. impl. rawm. soapfaultdetailimpl; Message = message + "reason =" + (soapfault. getreason () = NULL? "":
Soapfault. getreason (). getsoaptext () = NULL? "": Soapfault. getreason (). getsoaptext (). gettext ());
This Code only processes <faultcode> <faultstring>
<Detail> not handled 3) You can modify the <detail> part of the code on your own. Public void loop (iterator T, int I ){
Omelementimpl ome;
Omtextimpl OMT;
Object TX;
Char [] sapace1 = new char [I];
String sapace = new string (sapace1 );
Omchildreniterator tor = (omchildreniterator) T;
While (T. hasnext ()){
Tx = T. Next ();
System. Out. println (sapace + Tx. getclass (). getname ());
If (TX instanceof omelementimpl ){
Ome = (omelementimpl) TX;
System. Out. println (sapace + OME. gettext ());
Loop (OME. getchildren (), I + 1 );
} Else if (TX instanceof omtextimpl)
{OMT = (omtextimpl) TX;
System. Out. println (sapace + OMT. gettext ());
} Else {
System. Out. println (sapace + "other type ");
}
}
} and call this function at the bottom
If (ex! = NULL) {
throw new axisfault (Ex );
}else {
// If detail element not present create a new exception from the detail
string message = ""; Message = message + "code =" + (soapfault. getcode () = NULL? "":
Soapfault. getcode (). getvalue () = NULL? "": Soapfault. getcode (). getvalue (). gettext ());
System. Out. println ("" + message );
Iterator T = soapfault. getdetail (). getalldetailentries ();
Loop (T, 1 ); |
