Dear Axis's master:
I'm a programer using Axis2 1.4.1 to develope a Web Service application.
Now, I have met a problem about the famous "Must Understand check".
But my case is a litter special.
The detail is that :
I used org.apache.axis2.client.OperationClient API to construct a custom
SOAP message and send it to my Web Service like this:
......
MessageContext outMsgCtx = new MessageContext();
outMsgCtx.setEnvelope(buildOutEnvelope());
Options opts = outMsgCtx.getOptions();
opts.setTo(TARGET_EPR);
opts.setAction("urn:download");
operationClient.addMessageContext(outMsgCtx);
operationClient.execute(true);
......
By the SOAP Monitor and server log, I could judged that the Web Service did work
and returned desired SOAP message.
One of my Response message header block included mustUnderstand
attributes, such as:
...
<soap:Header>
<xxx:ID soap:mustUnderstand="1">42</xxx:ID>
</soap:Header>
...
#####
Please NOTE: It's in Response Message.
And then the following exception came out:
......
org.apache.axis2.AxisFault: Must Understand check failed for header ......

org.apache.axis2.engine.AxisEngine.checkMustUnderstand(AxisEngine.java:102)
at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:166)

org.apache.axis2.description.OutInAxisOperationClient.send(OutInAxisOperation.java:416)
at
org.apache.axis2.description.OutInAxisOperationClient.executeImpl(OutInAxisOperation.java:228)
at org.apache.axis2.client.OperationClient.execute(OperationClient.java:163)
......
At the server side, I could create a custom Handler in a module
and engage it to the Service to resolve this problem.
But now, it's Client. So how can I resolve this problem using Client API or
other method?
Could you have any ideas?
Thank you
