Technology - Angular JS - Angular UI components - Only well known and 'popular' extensions for table component ( no custom extensions ) - Server based on J2EE / EJB (no Spring) / JAX-RS Client should connect to the server via REST/JSON. Server functions must check if user is logged in. Application structure must be divided into clear components - servies /controllers. No fancy design needed - only simple tables.
