Hi, I am also interested in integrating a chat engine with my Struts application - with very similar requirements. In fact I posted a msg here before checking this thread !
I am not familar with any of the Sockets, ServerSockets, XML API or Threads. So looks like building from scratch is not an option to me; Smack sounds good, but with the problems you pointed out, I doubt if I am able to handle them correctly. Would you contribute your modifcation back to Smack someday ? appreciate your info very much ! lixin On 5/5/05, Erik Weber <[EMAIL PROTECTED]> wrote: > I just finished putting together a system with a Swing client and > combined services over XMPP and HTTP. > > I think Leon's suggestion of doing your own is not bad, if you are good > with Sockets, ServerSockets, XML APIs and Threads (find a good tutorial > on building a chat system such as in the ubiquitous "Thinking in Java"). > There is also JMS which gives you a low-level core.
