[Axis2] Need a small example with HttpSession

 Hi,

I'm a beginner with Axis 2 and I would like to know how to implement a stateful web service using HttpSession. I've spent several hours on this mailing but I've found absolutely nothing.
Can somebody supply a concrete example of axis session ? Any information in this regard will be highly appreciated.

Best regards,
Loïc

Thanks a lot for all the replies,

In order to manage HttpSession, I've tried the following code for my web 
service :

public class TestSessionService implements ServiceLifecycle {
    private ServletEndpointContext jaxrpcContext;

    public void init(Object context) throws ServiceException {
        jaxrpcContext = (ServletEndpointContext) context;
    }

    public void destroy() {
        jaxrpcContext = null;
    }

    public void tester() {
        HttpSession session = jaxrpcContext.getHttpSession();
        System.out.println("SESSION ID : "+session.getId());
    }

}

But I get this error when the getHttpSession() method is invoked :
org.apache.axis2.AxisFault: null; nested exception is: 
java.lang.NullPointerException

I think the object named jaxrpcContext isn't initialise in the init() method 
and is always null.
My source is this document : 
http://www-128.ibm.com/developerworks/xml/library/ws-tip-stateful.html

Any kind of help will be highly appreciated.

Best regards,
Loïc

ya , we dont have enough documents explaining session management stuff
(I am on the process of writing a document on this area).

Managing transport level session require you to change axis2.xml , need
to add the following parameter;
<parameter name="manageTransportSession" locked="false">true</parameter>

Then you need to deploy your services with its scope being
"transportsession" .

In the client side when you invoking the service you have an option to
manage session as well.

To understand the concept pls have a look at
http://svn.apache.org/repos/asf/webservices/axis2/trunk/java/modules/integration/test/org/apache/axis2/engine/ServiceGroupContextTest.java
