The interface changes are non-intrusive meaning that it changes or adds no functionality so if a class implements HttpSession it will also implement all the methods in ServletSession. To make catalina support the new interface have have made the following changes: org.apache.catalina.Session - changed to return a ServletSession in the getSession() method org.apache.catalina.session.StandardSession - makes it implement ServletSession and typecasts to HttpSession where needed. org.apache.catalina.session.StandardSessionFacade - makes it implement ServletSession org.apache.coyote.tomcat5.CoyoteRequest - typecasts from ServletSession to HttpSession in the getSession( boolean ) I'm not that thrilled by the patch, because we made the decision in TC 5 to work only with the HTTP protocol, for complexity reasons. Actually, it's merely the underlying protocol having to behave like HTTP (although the older TC 4.0 was supposedly protocol generic, it ended up being designed with HTTP in mind, so it wasn't much better). I know a bit the SIP spec, and that patch would sove the problem for sessions. How do you plan to solve it for the connector ? (the idea is that Coyote - supporting HTTP and JK - will remain the only supported connector in TC 5, the internal Catalina API being conserved for compatibility, or at least easy porting, of any old Catalina module) I don't see how there should be a problem with the connector, besides the fact that it has to also do outgoing connections. This only means that it gets a little more complex than the ordinary connector but not anything I have worries about. It is sad that you made that descision especially with the arrival of SIP Servlets that is the first real specification for using servlets for something other than HTTP. Before you could only guess as to how servlets otherwise could be used. But how will this decision affect the future of the internal Catalina API??? Will you deprecate all of it, just parts, redesign it all from scratch?? Like Remy, I'm -0 on the patch. As I read Remy's post, this means that neither of us will actually veto it if some other developer decides to post it. However, neither of us consider it to be a-good-idea, so we will be looking for implementation holes to veto ;-). Just try and find any holes ;-) It doesn't add a line of active code only interface change and typecasts. But what other reasons is there against the change other than the principal decision of only supporting HTTP in Tomcat 5??? And Remy himself says earlier in this thread "Actually, it's merely the underlying protocol having to behave like HTTP." And both SIP and RTSP behave much like HTTP given they both are designed with basis in HTTP. The problem is really that HttpSession and SipSession doesn't have any common interface, like say ServletRequest, so there is really no way to design a good interface in the container. I admit that the patch I sent is not that pretty. To call it a hack would more be the right term, but since the Servlet specification doesn't define a ServletSession interface how could it otherwise be done? I would really like to keep baseing my servlet containers on tomcat, since (for the most part ;-)) the interfaces are very well thought and designed. And I would really hate to have to start from scratch and make my very own container when a great deal of the foundation has allready been laid by you. The internal Catalina API (e.g. org.apache.catalina.*) is pretty stable. There are no current plans to change it. Pu eh!

Howdy, I'm also not a fan of this patch. I don't think it's a particularly good idea to modify the session interface for 4.1.x at this point.
