Hi Steve,
I've been reading your email over and over again and still not 100%
sure
what you meant... I've done lots of reading and research and trying to
put
the pieces together.... appreciate your help.
Without having web service in mind, this is what I had done (it's not
complete
yet, but just to share the idea with you).
1. I have MOServlet extends HttpServet. This servlet overrides
doPost()
and get parameters from request object. Then, pass the parameter
to
MOService instance.
2. MOService has a method "deliverMOMessage(...)" . This method
performs
validation on some of the params and insert the params into
database.
(I can't find ways to use JMS with MSMQ, so for now, I just use
database).
So to make this as a service:
1. I've created deploy.wsdd and undeploy.wsdd files. I used
AdminClient
to publich my MOService.deliverMOMessage(). So far I was able to
see this
when I ran the AxisServlet.
Question: The wsdl file is created on the fly, right? Does it
creates any other
files? I don't see other files generated. My server-config.wsdd
file was updated
to include the MOService. Is that all it does?
2. Based on your sample code below, few questions.
a. Do I need to extend AxisServlet instead of HttpServlet?
b. By extending HttpServlet, I thought I could do as follows:
MessageContext ctx = MessageContext.getCurrentContext();
SOAPMessage msg = ctx.getMessage();
.... go through until I get to SOAPBody.
c. Then I can use getChiildElements() to retrieve the
parameters.
3. Once I have all the params, I can pass them to MOService
deliverMOMessage(<params>).
So far, does this seems right? Appreciate your time.
Thanks,
--Kawthar

Hi Kawthar,
Axis is a servlet or server in your case.
The way to use web services in general is to have a normal java
application
that exposes services via an interface. These are just plain old java
objects.
Once you have an interface you can the run java2WSDL against the
interface to
generate a WSDL file that describes your service.
Once you have the WSDL you can then use WSDL2java to produce all or
your server
classes, your [un]deploy.wsdd and a whole host of serializable objects
and
Exceptions (if your service throws them).
If you have already implemented your service i.e. it runs but not
currently as
a web service you will want to tell WSDL2java not to generate the
server side
Stub. This will then create an Imple class that will also be the
deployed
service class in the [un]deploy.wsdd.
In the stubbed methods of this class you can defer all the calls to
your
implementation. The signatures of the methods should be identicle to
those
defined in your oridinal interface.
As you will already have a fully functional service just not as a web
service
all of the created serializable classes and exception created by
WSDL2java can
be thrown away and you can just keep the originaly implemented
objects.
Now you should have a deployable web service. Use the Axis Admin
Service to
deploy your web service and hey presto....
To retrieve the request that was made to invoke your service you use
the Axis
MessageContext to aquire the ServletContext from which you can then get
the
original Servlet Request and from there all of the parameters passed.
here is an example of how to aquire the ServletContext from within a
method in
the deployed Impl class.
org.apache.axis.MessageContext axisContext =
org.apache.axis.MessageContext.getCurrentContext();
javax.servlet.ServletContext sc = ((javax.servlet.http.HttpServlet)
axisContext.getProperty
(org.apache.axis.transport.http.HTTPConstants.MC_HTTP_SERVLET)).getServletContex
t();
Hope this helps you out and gets you on the road to creating some
useful web
services in the future.
Regards
Steve
