Webservice doesn't work with: soap-env:mustUnderstand="1"

[joan_ayala]

Hi friends,

I created a Webservice Consumer with the assistant, indicating the URL of my WSDL.

Then I created the logical port in SOAMANAGER, using the same URL.

When I test the Webservice Consumer I get the following error:

SoapFaultCode:3 MustUnderstand headers:

[Action,

To] are not understood.

The XML petition to the Webservice is:

<soap-env:Envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/">

People from my systems team, told me that if instead of having:

 soap-env:mustUnderstand="1" 

I had:

soap-env:mustUnderstand="0"

Then, It would work properly. Does anybody know if it is possible to change this value of the XML ?

Or any other solution can be helpful. Thanks !!!

Hi,

You can not modify the SOAP Request just like that. But it seems that your provider does not understand the WS-Addressing protocol properties. If this is synchrnous WS call ,you can try via soamanager to eclude addressing protocol via SOAMANAGER transaction.

Find your logical port , go to Messaging Tab and set Message ID Protocol to "suppressTransfer".

Best Regards,

Desi

I am getting the same 'MustUnderstand' error for standard BP Replication consumer proxy, I tried the 'SuppressTransfer' in the logical port definition but I am still getting the error, any ideas? Here's the question I posted with more details and error logs:

Thanks.
