chat application

[pavankumargupta]

hi all,

i'm developing chat application by using Java and UI with Laszlo.

on server side we are using third party tools to create chat application. From this we

able to send messages a member and a group.
able to receive offline messages.

the problem is, when user1 wants send msg to user2, he is sending message successuflly, and the message is displaying at Java console exactly and "unable to send to UI".

here, to get offline messages, on login request, we are checking the offline messages and sending to U-I as a response.

to chat online, an user has to get msg with out sending request to server. here i need Server Pushing data to UI.

is there any way to get this or any other design to get this (instead of server push).

thnaks in advance

regards
pavan.
