Hello All,
Need help calling a Webservice 

I have this endpoint 

http://efxpywsdev.informconf.com.py/Services/PDFServicePriv.svc?wsdl

i can create the proxy object with no problem

when i call any method in the WS it fails with the message:


no se puede reflejar el método reporteempresatipob 

this is the method definition 

reporteempresatipob ( long xitipopassword, boolean xitipopasswordspecified, longlong xlafiliado, boolean xlafiliadospecified, longlong xlpersona, boolean xlpersonaspecified, string xscontrasenia, string xsip, string xsruc, string xsusuario, ref byte lopdf[] )  returns string

 

i added the line to generate the log file and it is empty 

any way i can trace the root of the problem

Can it be cause bye the ref byte lopdf[]

Hi Andres;

  FWIW:  Your WSDL seems OK when I test it in the SOAPUI product ...

 

  You might need to contact the Web Service supplier on this issue to get more clarification on their error message.

 

Regards ... Chris

Yes

there are many .NET and Java application calling it with no problems.,

i´m checking the WS development team if they use reflexión and overloading.

Looking at thw WSDL file the relevant part contains:



or this:



or this:

My gut is telling me that this is the reflection, i.e. the function is overloaded which I believe PB cannot deal with.

Your choices are:

Edit the wsdl and remove the overloaded entries leaving only the one you want to use and PB might work.

OR

Abandon the PB proxy route and use the new http object to format and make the call manually.

 

Hopefully someone will confirm my suspicions.

Regards

David

Don't know why the viewer is losing the posted XML from the WSDL.

Hi

Your XML request is not XML data. This should be a formatted XML message with opening and closing tags.

For starters, your URL is wrong.  You don't ever want to call the service with "?wsdl" at the end.  That's just the location of the wsdl.  I'd also suggest using Fiddler to trap the actual request that gets sent and the full response.  Sometimes you get a better error message from Fiddler.  You said you were in touch with the ws developer, right?  Ask him to send you a request that works so you can compare it to yours.  you may also want to try SoapUI, as Chris did to at least get a good request (using Fiddler) and compare it to yours.

Also ask the ws developer if they have a REST version of the service. You may have more luck with that.

Hello,

Please check the source code that I am sending you, it would be very helpful if you could help with more data to test the wsdl.

Hola Juan,

Puede ser algún problema con la version del .NET framework?

veo que cuando compilas el proxy el return te sale como blob y en mi caso sale como byte[]

Eso es porque hice el export y he realizado el cambio de forma manual después hice el import nuevamente, pero prueba si te funciona, porque podría ser esa la solución, en todo caso si tienes parámetros de prueba que ayuden a probar el WebService podría ser mas útil para ayudarte.

Thanks to all,

this code seems to be working 

Constant Integer SECURE_PROTOCOL_TLS12 = 5
integer li_ret , i

arguments[1] = "0"

arguments[6] = "false"
arguments[7] = "'pass'"
arguments[8] = "20.000.000A"
arguments[9] = "1"
arguments[10] = "MARCELO_CLEMOTTE2_5053"

lo_xml_request = '' + &

'5053' + &

'[Aquí Psw]' + &
'20.000.000A' + &
'1' + &
' MARCELO_CLEMOTTE2_5053' + &

lo_client = Create httpClient
lo_client.SetRequestHeader("Content-Type", "text/xml; charset=utf-8")
lo_client.SetRequestHeader("SOAPAction", ls_soap_action)
lo_client.SetRequestHeader("Content-Length",string(len(lo_xml_request)*2))
li_ret = lo_client.PostDataStart(ls_url)
messagebox("RET - Start",li_ret)
if li_ret <0 then return
if li_ret = 1 then
messagebox("DATA",lo_xml_request)
li_ret = lo_client.PostData(lo_xml_request,len(lo_xml_request)* 2 )
messagebox("RET - PostData",li_ret)
end if
if li_ret <0 then return
li_ret = lo_client.postdataend()
 
now i need to get the response data 
correct me if i am wrong i must use:

GetResponseBody

or 

ReadData?

Remind me what you are expecting to get back? Is it a PDF file?



Technically you can use either depending on the response size. If you use Read Data in a loop you can get 1024 byte chunks and write them to disk to reconstruct your PDF file.



Glad I was able to help point you in the right direction and well done for getting the request working.



Cheers

David
