Dies,
I have created a client side handler, but how do I incorporate the same
to the client. My client is a servlet which consumes a WCF
service(Microsoft Indigo). Documentation says I can do it using
webserviceclient.xml. But mine is a web application created using Sun
studio and I can see a web.xml, not webserviceclient.xml. Any help?
Regards,
Girish Kumar

Hello Girish,
I am not sure what your question is but does my answer to Sajith (see
below: "employ a client-side handler that understands the header and
removes it from the SOAP message after processing it.") not help?
Axis 1.2/1.3 stubs do not understand other people's headers so headers
marked with mustUnderstand="1" will lead to the exception below. You'll
have to process (and then remove) the headers in client handlers.

Dies

Subject: Re: Problem with MustUnderstand headers when migrating from
axis 1.1 to 1.3
Hello Sajith,
Refer to the JAX-RPC1.1 spec to see how to use a client handler in a
portable way. I believe it goes something like this:
sf = javax.xml.rpc.ServiceFactory.newInstance();
SEIService si = (SEIService)sf.loadService(SEIService.class);
// register client handler
javax.xml.rpc.handler.HandlerRegistry hr = si.getHandlerRegistry();
java.util.List hl = new java.util.ArrayList();
hl.add(new
javax.xml.rpc.handler.HandlerInfo(YourHandler.class,null,null));
hr.setHandlerChain(new
QName("http://localhost/xxx/","yourPort";),hl);
SEI sei = si.getSEIPort();
((javax.xml.rpc.Stub)sei)._setProperty(Stub.ENDPOINT_ADDRESS_PROPERTY,
url);
YourHandler should implement javax.xml.rpc.handler.Handler.
Hope that helps,
Dies

Hi Dies,
As you suggested I debugged both axis 1.1 and 1.3 it seems Axis 1.1
does not
handle "mustUnderstand", where as axis 1.3 provides a handle
implementation
called "MustUnderstandChecker". This is the place where the error is
generated.
So either I could make changes to this class or I could have my own
handler
instead. Since I'm very new to web services I don't know how to
plug-in this
handler to axis. It doesn't seem like it cannot be externally
plugged-in to
AxisClient without modifying the existing 1.3 code.
Any thoughts on this will be highly appreciated.
Thanks and regards
Sajith.

axis
1.1 to 1.3
Hello Sajith,
The stub seems to generate a Fault when it receives a SOAP message
with
a header with a mustUnderstand="1" attribute.
I thought this was according to the spec, as the Axis generated stub
does not understand your header.
However, I believe some months ago there was some debate on this ML
whether Axis should be doing this, or whether the client application
should be responsible for this itself.
There was no conclusion.
If you get no response from others, you could try searching the
source
code for a comment regarding this change (as you said it used to work
fine with Axis 1.1, maybe you can find why it was changed, and then
judge whether that was a mistake or a new feature you'd have to work
with).
Otherwise, you could employ a client-side handler that understands
the
header and removes it from the SOAP message after processing it.
Good luck,
Dies
