I use axis1-4 for ws based auth and session management, this ties 
directly into my sessionbean using the providers and handlers from axis1-4.

If the context has a session then it talks to the same session bean 
serviceobject.  If the context has credentials then they are passed into 
jni to look up the ejb service object.

What I hope get from this architecture is container based transaction 
and security support without exposing transactions or neccessarily 
security through the wsdl. I could add another handler to map security etc..

I noticed when the session is reaped on timeout that remove() is not 
called on the session bean.  I might clone EJBProvider and implement 
ServiceLifecycle so I can call remove() on the destroy() event.

So why go to this effort in architecture to essentially pass the buck to 
the next component? I am essentially exposing a call-control sip stack 
through the ws. I have no place to do any core logic, or event routing, 
in the ws layer or in the stack as they both maintain session state and 
transactions in completley different ways, ie cookies and dialogs.

What I really want is a transactional context to say "detect the call 
has ended ! debit close the session and modify some database state, 
handle failure case, make endpoint callbacks etc" which I can't get from 
the sip stack (aka black box) and don't trust the web server to do 

Another reason is I automagically get pooling of service objects. Sure I 
have to authenticate twice a session, once in the ws and once in jni - 
ejb, but I don't have to worry about dos and cross host usage.  I don't 
really need session failover but that's another point for the ejb 
container (if supported).

I also get ejb timers facility and concurrency and synchronization. So I 
think its a win for coupling the two architectures togeather.

IMHO WS is not an application framework it's just another 
remoting/messaging technology primarily for .NET and monkey JEE interop. 
Otherwise why not just use IIOP? It's much faster! =)
