ZJF : ZJava Framework

ZJF provides components and solutions, that complement Swing when solving missing technology in Enterprise Internet Application market. ZJava is the only framework designed to provide everything you need, when you create polished, internet based, data-centric robust GUIs for Java environments.

Main Benefits

Creating sophisticated, professional, internet based rich applications.
Using custom components to build the next generation of internet-applications.
Reducing the complexity of Java Swing.
Being more productive with our innovative solutions.

Build your Enterprise Internet Application with ZJava

The main goal of ZJava product is to significantly reduce the effort and expertise required to build an Enterprise Internet Application which is deployed with WebStart . Nowadays client applications need communicating with a server and a database . ZJava simplifies the construction of these applications and reduces your maintenance issues.

By providing complete solutions that integrate all your needs from powerful Swing components to easy client-server communication , ZJava reduces development cost, and boosts your ROI .
Furthermore, if for some reason, you want to use just a few components or technologies , you can choose one of them , and use it for your Swing application.

Technology included in ZJava

 
 
ZComponent : Powerful customized components
 Providing all the components you need to build a rich application . For example , nowadays, you need more than a simple TextField . You have to get a DateField, a MoneyField etc ... From ZButton to ZAccordion, each component of ZJava, is extended from Swing components.
ZLive: No more "Please wait"
 Now experience live application interface. Just type a letter or click on a button and "Boum" you get the result !
These components are based on ZLive RealTime technology that reflects your input instantly ... without wasting time , without complexity.
DynaModel : Build your model and lose no time !
 Bored of writing hundreds of coded lines for a simple EntityBean ? DynaModel has done it for you, providing DynaBean and Table class, based on dynamic technologies !
In less than 10 minutes you can manipulate your data, send it to client and easily bind it with your components.
ZCom : Client-Server communication without complexity
 An independent communication interface easy to use ! It gives you a unique API to communicate with several protocols. For example : ZCom can support HTTP , WebService communications etc ... Default service is an ultra-fast half duplex communication, getting through firewalls.
Painter : Make Swing application, just beautiful !
 Personalize each component to your own visual identity, apply a gradiant to your TextField or fill a tiled image into your panel ... There 's no limit since you can add your own painter pluggins.
ZRenderer : Unified Renderer system
 

Unified renderer system, across all components (ZTable, ZList, ZComboBox, ZSelector etc ...) "Write once run every where"

ZJava includes several renderers at hand.

ZPlatform : Be Concentrate, on your killer-features
 Like a skyscraper, an application needs good foundations, ZPlatform provides a skeleton for your application, that enables you to concentrate on your features.
Border : Ready-to-use and attractive borders
 Zjava border pluggins offer ready-to-use and nowadays borders.You can add these borders to any component to match your own visual identity.
Printer : Print your screen !
 Printer API allows you to print a panel, a ztable or any zcomponent with a preview panel and printer connectivity.
ZEffect : Movie FX for Swing
 Apply movie special effects to your component ... just for fun or for status report . For instance, animate hidden parts of your user interface, let end-users understand what your application wants.
ZUtils : Missing utilities in Swing
Convenience functions and utilities class that help you achieve your goals. Such as Foxtrot which is an easy-to-use multithreading for Swing, LaunchBrowser, ComponentUtils, ZUIManager etc ...
