Stateful Web Services...

Hi to all,

As far as i understood, web services are stateless by definition. Although i already read some works about JAX-RPC and the possibility of creating a stateful web service. To do this we need to extend the javax.xml.rpc.server.ServiceLifecyle interface. 

Although i would like to know what are the developments in stateful Web Services. Is it possible already to have a full server running and responding to requests like for example a Windows DCOM Service? or a CORBA Server. These kind of server have their own cycle of life. For Web Services the cycle of life is controled by the Web Server, they are dynamically allocated when a request arrives and deallocated when that request/session ends. Also these kind of servers gives us the hability to maintain some usefull information in memory which can make their performance increse in several situations.

When this will be possible with Web Services? to have mass processing server running while some application server is running...

sem mais,
