Hi Merten,
You don't have to quite that much work. What you want is something like
this, right? Client makes a call to the service, and the server responds
and sets a cookie on the connection. From then on, the client sends back
that same cookie with each call and the server can check it.
A jaxrpc stub, normally, ignores the cookie that comes back. When you
set the SESSION_MAINTAIN_PROPERTY, then it will send back whatever
cookie the server set on it. So the client side is pretty simple.
On the server side, you need to do a little more work, but basically you
add one field to your class and a method that sets it. Have your
endpoint implement javax.xml.rpc.server.ServiceLifecycle. You will need
to add two methods, destroy() (which can be empty if you'd like) and
init(Object context).
Add a ServletEndpointContext object to your endpoint; I'll call it
myServletEndpointContext. In the init(Object context) method you can set
it: myServletEndpointContext = (ServletEndpointContext) context;
From then on, in your business methods you can get access to the
HttpSession with myServletEndpointContext.getHttpSession(). Note that
the first call to getHttpSession creates the session if one doesn't exist.
So in any method the client now calls, you can get the session, set
attributes on it, get information from it, or whatever, and from then on
the client will send back the same cookie information. See
http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/http/HttpSession.html
for information on the HttpSession object.
To answer your question about whether or not the session code is
generated for you behind the scenes, much of it is, but there's no way
to know what you want to do with the session information, so by
implementing javax.xml.rpc.server.ServiceLifecycle you can get the
session object yourself and do whatever you'd like.
Cheers,
Bobby
