AXIS Adapter - Remove mustUnderstand attribute

Question

We are using Axis adapter to insert a custom header into the soap envelope. The adapter automatically inserts the custom header with attribute mustUnderstand="0", but the receiver service raise a validation error since it is not able to recognize the attribute mustUnderstand. Is it possible to avoid the adding of this attribute?
Thanks,

Hi,
You mean that you need the information contained in the XI header.
I don't think you can directly turn off the mustUnderstand flag of the XI header.
But it is very straightforward to extract the information you need and put it in another header of your choice.
In this case, you can just use the HeaderExtractionHandler and HeaderInsertionHandler.
For example, suppose your XI header looks like
<sap:Main ...>
<sap:MessageId>062617a0-b1de-11df-b30e-c0a30a12c821</sap:MessageId>
<sap:Receiver>
   <sap:Service>Luzon</ns1:Service>
</sap:Receiver>
<sap:Interface namespace='http://luzon.com/leopard'>orderCheck</sap:Interface>
</ns1:Main>
and you want to extract the message ID, the receiver service, and the interface name into your own header
<x:MessageHeader soapenv:mustUnderstand='0' xmlns:x='urn:luzon.com:leopard'>
<x:msgid>062617a0-b1de-11df-b30e-c0a30a12c821</x:msgid>
<x:group>Luzon</x:group>
<x:action>orderCheck</x:action>
</x:MessageHeader>
What you need is the HeaderExtractionHandler placed before xireq in the receiver handler sequence
handler.type   java:com.sap.aii.axis.soap.HeaderExtractionHandler
namespaces     s http://sap.com/xi/XI/Message/30
path.1         s:Main/s:MessageId
name.1         sapkeys{msgid}
path.2         s:Main/s:Receiver/s:Service
name.2         sapkeys{receiver}
path.3         s:Main/s:Interface
name.3         sapkeys{action}
The above configuration will extract the required information in the map table sapkeys with keys msgid, receiver, and action, respectively.
And you need the HeaderInsertionHandler placed after xireq and before trp.
handler.type   java:com.sap.aii.axis.soap.HeaderExtractionHandler
value.1        <x:MessageHeader xmlns:x='urn:luzon.com:leopard'><x:msgid>{0}</x:msgid><x:group>{1}</x:group><x:action>{2}</x:action></x:MessageHeader>
arguments.1    sapkeys{msgid} sapkeys{receiver} sapkeys{action}
This will insert the above custom header filled with the extracted values.
