c++ - gsoap returns error 12 and "No user identifier provided" stream error -

i trying build simple gsoap client stuck. code, wrote.

    currencyratessoapproxy currproxy;      std::string login = "kav120@aubg.bg";     std::string password = "mypass";       std::string = "usd";     std::string = "eur";      _ns1__getlatestrate* getrate = new _ns1__getlatestrate;     getrate->singlecurrencyfrom = &from;     getrate->singlecurrencyto = &to;     getrate->password = &password;     getrate->userid = &login;       _ns1__getlatestrateresponse* resp = new _ns1__getlatestrateresponse;      if (currproxy.getlatestrate(getrate, resp) == soap_ok)          std::cout << "works";      else {         currproxy.soap_stream_fault(std::cout);          std::cout << currproxy.error;     } 

currencyratesoapproxy:

class soap_cmac currencyratessoapproxy : public soap { public:     /// endpoint url of service 'currencyratessoapproxy' (change needed)     const char *soap_endpoint;     /// constructor     currencyratessoapproxy();     /// construct engine state     currencyratessoapproxy(const struct soap&);     /// constructor endpoint url     currencyratessoapproxy(const char *url);     /// constructor engine input+output mode control     currencyratessoapproxy(soap_mode iomode);     /// constructor url , input+output mode control     currencyratessoapproxy(const char *url, soap_mode iomode);     /// constructor engine input , output mode control     currencyratessoapproxy(soap_mode imode, soap_mode omode);     /// destructor frees deserialized data     virtual ~currencyratessoapproxy();     /// initializer used constructors     virtual void currencyratessoapproxy_init(soap_mode imode, soap_mode omode);     /// delete deserialized data (with soap_destroy , soap_end)     virtual void destroy();     /// delete deserialized data , reset default     virtual void reset();     /// disables , removes soap header message     virtual void soap_noheader();     /// soap header structure (null when absent)     virtual const soap_env__header *soap_header();     /// soap fault structure (null when absent)     virtual const soap_env__fault *soap_fault();     /// soap fault string (null when absent)     virtual const char *soap_fault_string();     /// soap fault detail string (null when absent)     virtual const char *soap_fault_detail();     /// close connection (normally automatic, except send_x ops)     virtual int soap_close_socket();     /// force close connection (can kill thread blocked on io)     virtual int soap_force_close_socket();     /// print fault     virtual void soap_print_fault(file*); #ifndef with_lean     /// print fault stream #ifndef with_compat     virtual void soap_stream_fault(std::ostream&); #endif      /// put fault buffer     virtual char *soap_sprint_fault(char *buf, size_t len); #endif      /// web service operation 'getlatestrate' (returns error code or soap_ok)     virtual int getlatestrate(_ns1__getlatestrate *ns1__getlatestrate, _ns1__getlatestrateresponse *ns1__getlatestrateresponse) { return this->getlatestrate(null, null, ns1__getlatestrate, ns1__getlatestrateresponse); }     virtual int getlatestrate(const char *endpoint, const char *soap_action, _ns1__getlatestrate *ns1__getlatestrate, _ns1__getlatestrateresponse *ns1__getlatestrateresponse); } 

and ns1_getlatestrateresponse:

    class soap_cmac _ns1__getlatestrate { public:     std::string *unregistereduseremail; /* optional element of type xsd:string */     std::string *userid;    /* optional element of type xsd:string */     std::string *password;  /* optional element of type xsd:string */     std::string *singlecurrencyfrom;    /* optional element of type xsd:string */     std::string *singlecurrencyto;  /* optional element of type xsd:string */     struct soap *soap;  /* transient */ public:     virtual int soap_type() const { return 35; } /* = unique id soap_type__ns1__getlatestrate */     virtual void soap_default(struct soap*);     virtual void soap_serialize(struct soap*) const;     virtual int soap_put(struct soap*, const char*, const char*) const;     virtual int soap_out(struct soap*, const char*, int, const char*) const;     virtual void *soap_get(struct soap*, const char*, const char*);     virtual void *soap_in(struct soap*, const char*, const char*);              _ns1__getlatestrate() { _ns1__getlatestrate::soap_default(null); }     virtual ~_ns1__getlatestrate() { } }; 

i have no idea, doing wrong error 12 , "no user identifier provided" stream error. smth this:

soap 1.1 fault: soap-env:client[no subcode] "no user identifier provided" detail: [no detail] 

i dont think ""no user identifier provided" license info of service, because provided username , password. doing wrong? in advance
