Subject RE: Axis2: howto handle custom mustUnderstand Headers
Date Fri, 02 Nov 2007 11:07:23 GMT
Erratum:

Return InvocationResponse.CONTINUE if the header is OK, 

return InvocationResponse.ABORT if you want Axis to ignore the request.

Throw an Exception if you want the client to receive a SOAP Fault

Hi

No, you must not change the MustUnderstandChecker.

You must add a handler that will process your custom header. You have two things to do:

1/ Write the handler class

The simplest way to do so is to write a class that extends the AbstratHandler provider by
Axis (look up in the API docs for fully qualified name). Override the invoke method. In it's
body you will proceed the header the way you have to.
Return InvocationResponse.CONTINUE if the header is OK, InvocationResponse.ABORT in other
cases.

2/ Declare your handler class in axis configuration.

Edit the conf/axis2.xml file, and declare your handler in the inflow declaration (tag <phaseOrder
type="InFlow">), where the comments tells you to do it , like thos for example:

after the comment like this:

<!--   After Postdispatch phase module author or service author can add any phase he want
     -->
<!-- Samuel Rossille -->
	<phase name="myCustomPhase">
		<handler name="myCustomHandler" 				class="org.example.MyCustomHandler"/>
      </phase>


Tell me if you need more help.

Regards,

Samuel Rossille

Hi Samuel,

I saw your response in the newsgroup below. I still don't quite understand how to configure
it. Did you modify the MustUnderstandChecker or did you extend the class and put the code
in below? If the latter, did you then configure that class in the axis2.xml handlers? Is there
a document that talks about this?

Thanks in advance for all your help,

Thanks,
Rob
