Anyone and Everyone can use Oracle JET. It's an Open Source project sponsored by Oracle. It is distributed under the Universal Permissive License(UPL).
Yes, Oracle JET is distributed under the Universal Permissive License(UPL).
Oracle ADF and Oracle JET target different types of developer and focus on different development paradigm and architecture. Here are some of the high-level differences between the frameworks:
- Oracle JET has a code centric development paradigm, while Oracle ADF aims for a more declarative approach to development.
- Oracle JET is a pure client-side toolkit. Oracle ADF is a server focused framework.
- Oracle JET handles the creation of user interfaces, Oracle ADF handles the business service creation in addition to creation of UI layer.
- Oracle JET data interaction is via web services only (REST, WebSockets, SSE, etc). Oracle ADF support web service interaction with data services (REST/SOAP) in addition to direct binding approach.
Oracle JET is released on a regular schedule multiple times per year. The intent is to produce a predictable and consistent release schedule that teams can base their own development cycles on. There are two major releases per year with multiple minor releases in between each major. The major releases can contain API changes as well as new versions of dependent libraries such as Knockout.js, jQuery, etc. if they exist at that time. Minor releases are limited to bug fixes and additive, non-destructive features. The intent is for teams to be able to drop a minor releases on top of an existing application and not have to change any code other than the version path info.
The table below is the current plan of record. While we have been very successful in delivering to a predictable and consistent schedule, the dates provided are not a guarantee of delivery, and could change with short or no notice.
|22.214.171.124||Feb 29 2016 (Open Source Release)|
|2.2.0(New Semantic Versioning number scheme implemented)||Oct 2016|
|4.0.0 ( v2.x and older will reach End of Life(EOL) when this is released)||September 2017|
|5.0.0 ( v3.x and older will reach End of Life(EOL) when this is released)||April 2018|

Oracle JET is designed and tested against most modern HTML5 compliant browsers. Oracle JET will comply with the larger Oracle Software Web Browser Support Policy. Oracle JET is supported on the following user agents (i.e. browsing platforms):
|Chrome||Firefox||Internet Explorer **||Microsoft Edge||Safari|
|Android||Supported *||Not Supported||N/A||N/A||N/A|
|iOS||Not Supported||Not Supported||N/A||N/A||Supported|
|Windows||Supported||Supported||Supported (IE11 Only)||Supported||N/A|
Oracle JET is supported on the following hybrid (mobile) runtime WebViews:
|WebView||Min supported version||Operating System(s)|
|UIWebView||10.3||iOS 10.3 and above|
|WKWebView||10.3||iOS 10.3 and above|
|Android System WebView||126.96.36.199||Android 5.0 and above ***|
|Windows System WebView||10.0.14393.0||Windows 10|
The intent is to support the latest version of the browser available at the point JET releases and in some cases, such as IE and Safari, one previous major release. Please refer to the Oracle Software Web Browser Support Policy for any questions
* Support on the Android
operating system is limited to Chrome for Android. The Native Android browser
that shipped with version prior to 4.4.x is not supported.
** Support for Microsoft
Browsers will follow the same N-1 support policy that iOS provides. The most
recent version plus one previous release. As of January 12th 2016, this means
the most recent version of Microsoft Edge and IE11 only.
*** Android 5.0 shipped with
v36 of the Android System WebView, however the WebView should automatically
update on users' devices. If not, users can manually update it. The Android 5.0
(API 21) emulator uses v36, with which JET is not compatible.
Compatibility Mode: For Windows Browsers, only Native mode is supported. View Compatibility mode should be disabled.
RTL Languages: Support for RTL (right to left) languages, such as Arabic or Hebrew, is available with supported versions of Microsoft Browsers, Firefox, Safari, and Chrome.
Doctype: We rely on CSS attribute selectors, some versions of IE support attribute selectors only if a !DOCTYPE is specified, therefore to use JET on IE a doctype is required.
Starting with the v2.2.0 release of Oracle JET we started following the Semantic Versioning standard for product numbering.
|1st||2.0.0||MAJOR version when incompatible API changes are possible.||Any change to the first digit indicates a revision/migration of an application is necessary. We do not guarantee an application written between changes of this release number can be migrated to the next major version without possible code changes. These releases are also used for updating libaries that Oracle JET has dependecies against. (e.g. jQuery, Knockou, RequireJS, etc)|
|2nd||2.1.0||MINOR version when functionality is added in a backwards-compatible manner.||This release may contain new features as well as bug fixes that are non-destructive in nature. It does not require an app to change any APIs, and should be drop-in compatible with the previous major release that it is a minor of. Application will be required to change the version string in file path references.|
|3rd||2.1.1||PATCH version when backwards-compatible bug fixes are made available for security or catastrophic issues only.||This type of release is rare and only produced when a security issue, or a bug that causes a browser crash, needs to be fixed. It should be drop-in compatible with the previous major release that is a minor of.|
Oracle JET tooling requires Node.js v6+ and npm v5.6.0+ or v4.x to be installed. It is highly recommended that you use the LTS version of Node.js
