Web service client in Progress V9.1e

[mokeyh]

Hello,

Can anyone help - I need to run/consume a web-service from a Progress V9.1e client. The web service is up and running and I can run it with no problems from an Openedge (V10) client.

I have tried and failed...

Firstly, here is my working V10 code:

/*v10 code...*/
DEFINE VARIABLE hWebService AS HANDLE NO-UNDO.
DEFINE VARIABLE hWorkFlowWSService AS HANDLE NO-UNDO.
DEFINE VARIABLE o-session AS CHARACTER NO-UNDO.
CREATE SERVER hWebService.
hWebService:CONNECT("-WSDL 'http://rapsbmdev:18793/sbm/services/BizLogic1?wsdl'
-Service WorkFlowWSService
-Port BizLogic1").
RUN VALUE("WorkFlowWS") SET hWorkFlowWSService ON hWebService.

/* Procedure invocation of START operation. */
RUN connect IN hWorkFlowWSService ( INPUT "user",
INPUT "password",
OUTPUT o-session).
MESSAGE "o-session" o-session VIEW-AS ALERT-BOX INFO BUTTONS OK.
RUN DISCONNECT IN hWorkFlowWSService (INPUT o-session).


And here is my (non-working) v9 attempt...

As you can see I'm using sockets directly and constructing my own SOAP message. The connect seems to work ok and the write to socket returns no error. But I am not getting a response from the web-service and I suspect my XML may not be being received or may be incorrect somehow...

Any help would be greatly appreciated! Many Thanks.

How about connecting your 9.1E client to a 10 AppServer and letting that do the work?

 

[Marian EDU]

are you sure this goes without error???

SET-SIZE(v-mData) = LENGTH(lv-xml). 
PUT-STRING(v-mData,1,LENGTH(lv-xml) ) = lv-xml.

other than that, grab a http sniffer and see what is the exact soap message sent by the OE10 client

 

[mokeyh]

The httpsniffer sounds useful - can you recommend one in particular?

Yes, there is no error from the two lines you mentioned, although the progress help on the put-string command does not tell you to put the = in - it will not compile without...

Thanks.

I like fiddler. Check out www.fiddler2.com

Check SoapUI and emulate query to web service.
