Short Demo


Background

Batch Operations are among the most critical operations performed by IT staff in a bank

Batch Operators need an easy to use system to help them maintain batch jobs across systems and monitor them in real time

Pilot project utilizing Java FX and JEE 7 to help address this space

User Interface – Why JavaFX ?

Productivity– Rapid Application Development using Tooling (Netbeans and

SceneBuilder)

– Testing and…

– We are coding only in Java

Why JavaFX ?



Capability– Layouts built using WYSIWYG

– Control Set (Basic and Advanced)

– Eventing (e.g. Value Change Listeners, Thread State Listeners)

– CSS styling

Why JavaFX ?



Monitoring using VisualVM Stability and Acceptance

– Extremely Performant

– Class of users are familiar with Desktop Applications

Why JavaFX ?


User Interface – Views

FXML

VIEWS

Screen Building using Scene Builder

which generates FXML– Layout Containers

– Place Controls

– Associate Events

– Style

Associate


User Interface – Controllers

Java Class which has– Controls injected using “@FXML”

– “Service” threads to load data

– Event listeners to populate data

or respond to other events

Controller Implementation


User Interface – Client Services

Controllers use JAX-RS 2.0 clients to load data with Eclipselink

MOXy as the JSON Provider

JAX-RS 2.0 (JSR-339) Client API
