Hi Robert,
Thanks for your quick reply. What you answered to my first problem seems to
be what I'm looking for, so you udnerstood me correctly :) Since in JMX the
MBean server does the instancing of classes for you ServiceObjectSupplier
will work great. The problem is, as you say, that you have to define the
ServiceObject in the services.xml file. What I would like to do is to
deploy using code. So when our middleware discovers a a new component in
its deploy folder it will load it as a MBean and then create a soap service
pointing to that mbean. Creating a new service in the way axis deployes its
services will be problematic. Creating a way to dynamically deploy soap
services is what's needed for us.
Since I'm not to familiar with the codebase of axis 2 I would appreicate it
greately if anyone could tell me how to deploy services from code or could
point me to the correct files so I could found out for myself.

Hi Dan,
I'm interested in what you're doing with JMX, as I do a lot of axis2
programming with JBoss / EJB which as you may know is a very heavily
user of JMX. See my comments inline:

Hello,
I'm a master degree student from the university of Tromsø working on
a middlware platform for context sensitive services. The middlware is
built by using MBeans (JMX http://java.sun.com/products/JavaManagement)
and Axis 2 has been installed on an embedded installation of Jetty
5.1.11RC0.
We want to make it possible for components deployed in the middleware
to expose certain methods as web services using axis 2. When trying to
use the API some problems have arisen.
The two problems I encounter when trying to do this is:
1. A way to register already created objects as a service, so I supply
the instance of the object (the component) instead of axis 2 creating
the instance for me.
You happen to be lucky and this issue was just implemented in recent
days - if I understand you correctly ;-) . In my case I did the Spring
support that does its own loading of objects, but ran into the same
issue. The Spring classes haven't been updated yet, but hope to do
that in the next few days.
In the latest svn take a look at
modules/core/src/org/apache/axis2/receivers/AbstractMessageReceiver.java
You can now define ServiceObjectSupplier as you would ServiceClass in
your services.xml, and return your object as you see fit.
2. A way to programmatically register services. This most also be
possible
at runtime as the middleware supports hot deployment.
So what I'm looking at creating (if it doesnt already exists) for our
middleware is something like this, pseudocode:
//My component I want to register
Component comp = Middleware.getComponent("Component Name");
//Methods the service should expose, everything
Method[] methods = comp.getClass().getMethods();
//Singelton pattern
Axis axis = Axis.getInstance();
//Deploy Service
axis.deployService("Service Name", comp, methods);
If does not exist already it's something I would like to create. I'm
sure
it
would be usefull for others aswell. Where would one start to create
something
like this?
This is not the area I typically work on, though I'll take an educated
guess. Others may be able to give better advice.
You either need an axis2.xml or you can create one programatically via
AxisConfiguration . From there you can go with the exploded dir
options as this tutorial explains:
http://www.wso2.net/kb/90
AFAIK, however, the exploded dir option is not hot deploy. To do that,
my possibly completely wrong thoughts, based on entirely too much
world cup fever, would be:
1) First get the axisConfiguration as descibed above.
2) Then get the AxisService corresponding to the service to create from
axisConfiguration.
3) AxisService createService(String implClass, AxisConfiguration
axisConfig) throws org.apache.axis2.AxisFault;
4) To invoke:
new ServiceClient(ConfigurationContext configContext, AxisService
axisService);
serviceClient.sendReceive(OMElement);
