Hi I want to write a chat but not a chat with a topic but point to point between users : (un = 1 user) u1<--1:1-->u2 u3<--1:1-->u2 u3<--1:1-->u1 Each user can connect on the chat at anytime I'm newbie on JBossMessaging. Actually my orientation choices (certainly not all good...)are : -IHM client : applet -use QUEUE because this is a point to point, a conversation between 2 users -For 1 converstation between 2 users i need 2 QUEUEs : each user can send or receive message -Each user can connect / disconnect himself at any time : for this it is need to create a queue when a user want to be connected and destroy the queue when the client disctonnect it'self : for this each applet can will create/destroy new queue on the server via JMX on jboss.messaging:service=ServerPeer If some experimented people can give me it s remarques..
