To get a feel of an Oracle JET application check out the "WorkBetter" JET Demo:
Oracle JET provides a rich set of Oracle JET UI components that you can use out of the box (based on Alta UI). The documentation contains code snippets which can be used to integrate the desired UI controls in your application. (If you are a business user (with a certain affinity and love for IT) you will be able to use Oracle JET components inside "Oracle Application Build Cloud Service" )
For data visualization it is almost the complete set you may know from ADF. This is pretty cool.
Oracle JET (Enterprise) FeaturesComparing to other UI Toolkits it is great to see that important aspects of every enterprise application has been addressed.
- Support for localization & internationalization
- UI Components are implementing the latest WCAG 2.0 / WAI-ARIA accessibility guidelines
- Theming support - Default is Alta UI
- Security - Oracle JET API provides the oj.OAuth authorization plugin which supports the OAuth 2.0 open protocol
How does it compare to ADFWell,
