PB & web service : how to manipulate soap envelop ?

Hi all,

I am in the process of testing PB's ability to consume an existing web service. I have done some reading left and right.

I can create the proxy , but i always end up having the Cannot invoke webservice messagebox.

Here's my little piece of PB code

PB CODE START

soapconnection conn // Define SoapConnection

checkvatport proxy_obj // Declare proxy

long rVal, lLog

real amount

date date_a

string ls_a,ls_b,ls_c

conn = create soapconnection //Instantiated connection

lLog = conn.SetSoapLogFile ("C:\mySoapLog.log")

rVal = Conn.CreateInstance(proxy_obj, "checkvatport", "")

messagebox("test rval",string(rval))

// Create proxy object

try

date_a = today()

boolean w_t

w_t = TRUE

str_checkvat str1

tns1__checkvatresponse str2

str1.countrycode = "BE"

str1.vatnumber = "0810416786"

ls_a = proxy_obj.checkvat(str1.countryCode,str1.vatNumber,str2.requestdate,str2.valid,str2.address)

messagebox("LS-a",ls_a)

catch ( SoapException e )

messagebox ("Error", "Cannot invoke Web service")

// error handling

end try

destroy conn

PB CODE END

And here's the soaplog contents

SOAPLOG START

Now i tried the to cut and paste the above soap envelop in SOAPUI , and it gives me the exact same error message as in the soaplog.

I then tried creating a request through SOAPUI but based on the wdsl ,SOAPUI is giving me a different soap envelop as the one PB generated ?

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:ec.europa.eu:taxud:vies:services:checkVat:types">

<soapenv:Header/>

<soapenv:Body>

<urn:checkVat>

<urn:countryCode>?</urn:countryCode>

<urn:vatNumber>?</urn:vatNumber>

</urn:checkVat>

</soapenv:Body>

</soapenv:Envelope>

If i enter parameters in the above envelop and check it through SOAPUI , i end up having the result i want.

Is there any way we can manipulate the soap envelop contents ? Or does anyone have any idea why the soap envelop generated by PB ends up having the above mentioned error in the soaplog file ?

What am i missing ?

TIA
