Trouble with XMLPort via codeunit/web service

chrisgrill3 · 2010-05-05

The SOAP request gets there and fires off the code unit, but the xmlport always fails. I tried to use GETLASTERRORTEXT but it returns nothing. The SOAP returned always has blank values in the xml, just the elements. Some of the lines are pasted from emacs and may have trailing slashes from emacs line breaks. Any thoughts would be greatly appreciated. Here is additional info:
Here is my codeunit:
WebOrderImport(VAR WebOrderImportXMLPort : XMLport "CK Web Order Import") ReturnText : Text[80]
IF WebOrderImportXMLPort.IMPORT THEN BEGIN
ReturnText:='Web Order imported.';
COMMIT;
WebOrdProcessingGCdu.ValidateWebOrders;
WebOrdProcessingGCdu.MakeSalesOrders;
END ELSE
ReturnText:='Web Order Not Imported, Try Again';

Here is the WSDL for the web service it exposes:- <definitions targetNamespace="urn:microsoft-dynamics-schemas/codeunit/WebOrderImportService" xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="urn:microsoft-dynamics-schemas/codeunit/WebOrderImportService">

I found that working with XML Ports and Web Services didn't work as well as advertised with NAV. I found it much easier to implement error trapping and other handling by accepting XML via a parameter of BigText type (which is basically a string in C# or VB.NET).

This makes it really easy for any calling process to pump in XML - although you don't get the nice type definitions in the Web Proxy that is created in Visual Studio. But I think it can be much easier to document and sort through problems in the interface if you accept a simpler data type (i.e. BigText).

when I was working through testing of my web service interface (a codeunit which then called an XML Port) it was simple to dump the string that was submitted to NAV to file, review the XML in the file and try to debug where the problem came from.

There are two basic principles when using XMLPorts in Webservices:

1. The name of the parameters of a function will start with a lower case character when exposed as a webservice. In this case: webOrderImportXMLPort.
2. The name of the parameter that points to a XMLPort must be exactly match the name of the root element of the XMLPort.

If one of these requirements is missing you might have the behavior that you are struggling with.

We decided to expose the page as a web service and am using SOAP to call methods from the page successfully.

Howdy, Stranger!
