Passing object as parameter to web serviceNapisao sam web service koji u sebi ima funckiju koja prima objekte kao parametre.
Kada god pokusam da pozovem tu funkciju iz aplikacije, dobijem sledecu poruku:
An unhandled exception of type 'System.InvalidOperationException' occurred in system.xml.dll
Additional information: There was an error generating the XML document.
Inace imam 2 classes,
Public Class Workstation i
Public Class Server
Funkcija koja se nalazi u web service je
<WebMethod(Description:="Log installation steps into the database.")> _
Public Sub LogProgress(ByVal oWorkstation As Object, _
ByVal oServer As Object, _
ByVal strStage As String, ByVal bolSuccess As Boolean, ByVal strMessage As String)
Dim objServer As New MaxiomBusinessObjects.Server
Dim objWorkstation As New MaxiomBusinessObjects.Workstation
objWorkstation = CType(oWorkstation, MaxiomBusinessObjects.Workstation)
objServer = CType(oServer, MaxiomBusinessObjects.Server)
....
ovde sam morao da koristim ctype jer funkcija nije htela da primi Workstation i Server objekte kao parametre.
Code koji zove ovu funkciju u klijent aplikaciji izgleda ovako:
Dim MyWebService As New MaxiomWeb.Service1
Dim oWorkstation As New MaxiomBusinessObjects.Workstation(GetWorkstation(), GetOS(), GetCPU(), GetMemory(), GetFreeSpace("C:\"), CType(GetTotalSpace("C:\"), Long))
Dim oServer As New MaxiomBusinessObjects.Server(GetServerName(), GetServerID())
MyWebService.LogProgress(oWorkstation, oServer, "Test stage", True, "Testing, testing...")
Pomozite ako znate, mucim se vec pola dana oko ovoga...
