Re: NET Client omit NULL Parameter - handling

Tue, 08 Mar 2005 16:33:23 -0800

Also -- If you don't put the parameter names in the WSDD file, then Axis does function parameters by position, rather than by name.... which tends to lead to the problem listed in the mail.

Example:
<operation name="getDocument" qname="operNS:GetDocument" xmlns:operNS="http://beacon-it.co.jp/inicio/schema"; returnQName="GetDocumentReturn" returnType="rtns:Document" xmlns:rtns="http://beacon-it.co.jp/inicio/schema"; soapAction="" >
<parameter qname="login" type="tns:Login" xmlns:tns="http://beacon-it.co.jp/inicio/schema"/>
<parameter qname="path" type="tns:string" xmlns:tns="http://www.w3.org/2001/XMLSchema"/>
</operation>

Are you using the deploy.wsdd generated by Wsdl2Java?

Hello Dino,

the problem is not the Array of int's the Problem is the
String itemName.

As you see in the generated request it is missing in the Request,
if it is null. Axis on the serverside, now treating the third
Parameter: fromTimestamp as Parameter itemName and fails
with an expeption converting that long to an String.

It appears you are using soapenc:Array, which is a WS-I no-no.  Why not
use doc/literal?
Also, for an example of transmitting arrays of complex types, between
AXIS and .NET, see
http://dinoch.dyndns.org:7070/axis1.2/AboutCtService.jsp
It is a working app. Uses doc/literal.   The source is downloadable.  I
don't have any problems, as far as I know, sending "null" params.
(sending null dates is a different matter)

Subject: NET Client omit NULL Parameter - handling

Hello,

i have a Problem with Axis (1.2RC3) and a .NET 1.1 (C#) Client.

Making a Request from the NET Client with a String - Parameter = null.
The generated Request omits the Parameter (eg. itemName)

But it seams Axis is not using the Parameter-Names, it is deserializing
parameter after parameter, so the call results in an Exeption.

Is there any Solution for this ?

Thanks for your Help

Regards

Robert
