OK, onda ovako:
servis cije metode pozivam je na JRun-u i naravno, napisan u Javi.
Servis nije kod mene vec kod klijenta.... nemaju WSDL i iz VS-a ne mogu se tek tako
nakaciti na njihov servis da bi VS jednostavno generisao sav taj potrebni kod (WSDL a onda i refference.cs...).
Zato sam od vlasnika servisa trazio da mi posalju Java kod klasa koji se koriste kao input ili output parametri
u komunikaciji.
Nakon sto su poslali, a znao sam potpise metoda koje treba zvati, znaci sta vracaju i primaju od parametara,
napravio sam sebi testni servis u Javi koji implementira iste metoda (doduse bez logike u njima, jer mi je potrebno
samo da ih poziva zasad) i deployao ga na tomcat. Iz VS dodao WEB referrence i sve je ok, generisao WSDL i referrence i to radi divno.
Medjutim, nakon sto sam se nakacio na pravi servis nastao je problem deserijalizacije o kom sam govorio.
Evo koda:
Code:
// kod java Methoda getNextUpdate koji je eksportovvan u Java servisu i treba ga pozivati iz klijenta (postavicu samo potpis jer je tijelo ogromno):
public Vector getNextUpdate(Ticket inticket, String systemid) {
...
...
}
// kod istog tog metoda koji je generisao VS na klijentskoj strani:
/// <remarks/>
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("", RequestNamespace = "urn:SesamSimulatorService", ResponseNamespace = "urn:SesamSimulatorService", Use = System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle = System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
[return: System.Xml.Serialization.XmlElementAttribute("return", Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
public object[] getNextUpdate([System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)] Ticket arg0, [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)] string arg1)
{
object[] results = this.Invoke("getNextUpdate", new object[] {
arg0,
arg1});
return ((object[])(results[0]));
}
Greska koju dobijam kad pokrenem klijenta i pozovem getNextUpdate method:
Code:
getNextUpdate Error msg: No Deserializer found to deserialize a ':arg0' using encoding style 'http://schemas.xmlsoap.org/soap/encoding/'.
Kod spornog parametra, tj prvog argumenta u funkciji getNextUpdate:
Code:
// originalni Java kod:
public class Ticket
{
private String bestallare;
private String loginmetod;
private String klientipnr;
private String anropipnr;
private String anropmetod;
private String tid;
private String ovrigt;
// IZOSTAVLJEN KOD METODA I KONSTRUKTORA
}
// kod koji je generisao VS:

Sta jos, koristio sam HTTP/HTTPS analyzer da skontam sta saljem i sta vracam i dobio:

eto, mislim da je dosta informacija :) a pomoc zaista potrebna ;)
Samo se budala saplice na kamen iza sebe.
SOAP - deserijalizacija - problem
