WS Security Handler - Header element properties not accessible

Hi all,

I have configured a Web Service Consumer (WSD) following the step described in “7.1.1_Web_Services_Delevoper_Guide.pdf” using WS Security capabilities and policy files.

When running WS Consumer following SOAP-FAULT is returned :

faultcode :soapenv:MustUnderstand
faultstring:Did not understand “MustUnderstand” header(s):{}Security

I am unable to modify the mustunderstand property (to false) as WS Security Handler - Header element properties is not accessible on Developer.

Appreciate any feedbacks.

Kind Regards,

As per link below the problems is apparently in Axis side (web service provider).


Axis doesn’t handle mustunderstand attribute.

Does anyone know how can i suppress the mustunderstand attribute in WS Security SOAP Header in webMethods 7.1.2 ?


Using a custom SOAP Handler will give you full access to all aspects of the SOAP Header and Body, so you can customise the payload XML to work round any issues.

Thanks for your reply.

That’s what i finally did in some way. I reused a previous 6.5 WS Connector and added a document-based WS Security header using addHeaderEntry service.

However I still don’t now how to suppress the mustUnderstand tag in 7.1.2 WSD, bug or product bad design. This is webMethods.

Thanks again.


I am trying to change the mustUnderstand to “0” from the default value of “1” too. Have you or anyone resolve this problem?
