.Net Client calling Apache WebService: Problem with NULL-Values

Jens

Hello,

i am trying to call a Apache WebService, which accepts NULL-Values for
some Parameters of a specific Web-Method. NULL-Values are mapped
within the soap-request by the .NET Client corresponding to the
following example-schema:

<ffin xsi:nil="true" />

the problem is that Apache expects the following request-schema:

<ffin xsi:type="xsd:s tring" xsi:nil="true"/>

otherwise Apache responds with an exception.

How can i get my .Net Web-Service Client to add the
missing "xsi:type" attribute

Thank you for your answers!

Have you consulted http://ws.apache.org/soap/docs/guide/interop.html
?

Could it be that you are experiencing the soap interop problem described
therein ?

With Apache SOAP v2.x, there was an issue that the Apache soap runtime
required incoming SOAP envelopes to embed an xsi:type on every param. The
SOAP spec does not require this, but the Apache SOAP implementation did.
Implementations of SOAP (such as .NET ) that did not embed xsi:type into
every param tended to confuse Apache SOAP. There is a workaround.

The other (preferred?) workaround is to move your Java implementation to
Apache AXIS. ;)
