c# - Call web service method returns null in VS 2008 -

my situation: have winform app (.net 2008) , have consume web service (java axis). i´m using soapui test web service , works fine. when use via service reference in vs 2008 returns null.

apparently, seems known problem , has solution. sorry, cant find solution time!!

there other cases mine (like this), not working me.

i reading many forums on site, , more. cant find solution.

thanks everyone.

actually solved (temporary, caveman) doing web request , reading web response. working? yes, think it's not way, not quality way.

i think must solved, somewhere, somebody.

i did this:

using cliente new webclient()      cliente.headers.add("soapaction", """http://wds2.ar.bsch:9089/wsfdaxis/services/soapmessagedispatcher""")     cliente.headers.add("content-type", "text/xml; charset=utf-8")      dim mensaje string = string.empty     mensaje &= "<soapenv:envelope xmlns:soapenv=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:ser=""http://services.web.wsfd.bancorio.com.ar"">"     mensaje &= "    <soapenv:header/>"     mensaje &= "    <soapenv:body>"     mensaje &= "{0}"     mensaje &= "    </soapenv:body>"     mensaje &= "</soapenv:envelope>"      dim data = encoding.utf8.getbytes(mensaje)     dim result = cliente.uploaddata("http://wds2.ar.bsch:9089/wsfdaxis/services/soapmessagedispatcher", data)      dim xml = new xmldocument()     xml.loadxml(result)      dim nodes = xml.getelementsbytagname("codret")      dim codret = string.empty      each node xmlnode in nodes         codret = node.innertext     next      return cint(codret) = 0  end using
