MessageContext and OperationDesc

[Brian Madigan <bu...@yahoo.com>]

Handler implementation question:
Do MessageContext instances that get passed to
Handlers have an OperationDesc? I see that
OperationDesc is a 'Work in progress' in the API. Is
there a way (that works) to get the name of the
operation in the current MessageContext? (from within
a Handler)

Also, how volatile can I expect MessageContext to be?
Should I keep it in hidden in my handler or is it
closed enough to change that I could depend on it to
some degree?

How to add a SOAP header into a SOAP envelope ??

[Ricky Ho <ri...@cisco.com>]

I try to add a SOAP header into a SOAP envelope.

1) SOAPEnvelope soapEnv = .... ;
2) System.out.println("SoapEnv is ..\n" + soapEnv);
3) SOAPHeaderElement hdrElement = new SOAPHeaderElement(new 
PrefixedQName("myNamespace","someHeader", "prefix"));
4) soapEnv.addHeader(hdrElement);
5) System.out.println("SoapEnv is ..\n" + soapEnv);

At line 2, I get ...

SoapEnv is ..
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <soapenv:Body>
   <ns1:getTemp 
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 
xmlns:ns1="urn:xmethods-Temperature">
    <zipcode xsi:type="xsd:string">95135</zipcode>
   </ns1:getTemp>
  </soapenv:Body>
</soapenv:Envelope>

But I get an Exception after line 4

Exception:
java.lang.NullPointerException

At line 5, I get the following

SoapEnv is ..
null

What have I done wrong ??
