Web Service with SOAP attachment.

[Former Member]

Hi,

I have a webservice which takes one parameter as a string, and takes another parameter as a SOAP attachment.

I have implemented this as a stateless EJB (as suggested in the tutorials).

However when I post to the web service, it doesnt seem to be able to get the soap message, and gives the following error (in the soap envelope):

com.sap.engine.services.webservices.espbase.server.additions.exceptions.ProcessException: Deserializing fails. Nested message: Expected parameter element with name source, found correlationId..

For reference the parts in the wsdl are:

<message name="submitMessage">

<part name="correlationId" type="xsd:string"/>

<part name="source" type="xsd:anyType"/> </message>

and the mime aspect as follows:

<input>

<mime:multipartRelated>

<mime:part>

<soap:body use="literal" namespace="http://mynamespace/" parts="correlationId"/>

</mime:part>

<mime:part>

<mime:content part="source" type="text/xml"/></mime:part>

</mime:multipartRelated>

</input>

I have checked the packets going to the server and the SOAP attachment is definately there. Just seems like the sap engine cannot parse the attachment and reconcile it to one of the parameters.

Any ideas?

Regards,

Andrew

Hi.

I seem to have found the solution.

It is a change to the wsdl to include a binding.

Many thanks for your help.

Hi Andrew,

Would you supply the whole wsdl file, we would like to check it on our own?

Thanks in advance.

Dimitar,

The wsdl is shown as follows.

(Some namespace changes from initial posting, but this is the one we are using.)
