Share Code- Chia sẻ code EJB EAD - TMS

Android => SmartPhone

=> device token => Server Google (CH Play)

Zalo/Facebook

Device (You) => send message => Server Zalo/Facebook (device token (nguoi ma ban muon gui message)) => send message => server google (CH Play) => push notification => device (nguoi ma ban muon gui tin nhan)

==========================

TMS => giong het vs push notification tren

EJB (EAD)

Project

- EJB (EAD) => app server => TOCAT/Glassfish (Server) - Local (PC cua cac ban)

- Client (App console, App Swing, Web App)

Client (A) => send message => Server App (EJB, EAD) => send message to Client (B)

Topic/Queue

- Cac buoc phat trien 1 du an TMS trong Java Web (EJB/EAD)
