    JAVA PLATFORM, MICRO EDITION (JAVA ME)

    Java Platform, Micro Edition (Java ME) provides a robust, flexible environment for applications running on embedded and mobile devices in the Internet of Things: micro-controllers, sensors, gateways, mobile phones, personal digital assistants (PDAs), TV set-top boxes, printers and more. Java ME includes flexible user interfaces, robust security, built-in network protocols, and support for networked and offline applications that can be downloaded dynamically. Applications based on Java ME are portable across many devices, yet leverage each device's native capabilities.

    Oracle Java ME Embedded is a Java runtime that leverages the core Java ME technologies deployed in billions of devices around the world in the Internet of Things. The Java ME specifications are designed to be rich in functionality, portable to a wide range of devices, flexible, and secure while being very resource-efficient and keeping the demands on the underlying platform low.

    The Java ME Software Development Kit (SDK) provides device emulation, a standalone development environment and a set of utilities for rapid development of Java ME applications. It integrates the Connected Limited Device Configuration (CLDC) and the Connected Device Configuration (CDC) technology into one simple development environment.

    Oracle Java ME Embedded Client enables you to develop highly functional, reliable, and portable applications for today's most powerful embedded systems. The flexibility of the Java Platform coupled with and established developer base enables you to develop secure, innovative products while achieving enhanced cost savings and time to market advantage. A vital platform that offers industry-leading reliability, performance, throughput, security, and cross-platform support.

    The Connected Limited Device Configuration and the Java ME APIs are used by a vast number of Java mobile phone developers, carriers, and OEMs to create feature phone products around the globe. Oracle is the leader in providing mobile phone technology found on over three billion devices and counting.

    Java TV is a Java ME-based technology that provides a performant, secure, and easy to implement solution for developing Java applications that run on TV and set top box devices. Using the Java TV runtime, a developers can easily create applications, such as Electronic Program Guides (EPG's), Video-on-Demand (VOD) clients, games and educational applications, applications for accessing internet data (e.g. weather, news tickers, social networking), and, on most Blu-ray Disc titles, the user interface and bonus content.

    Extend the reach of Java in the Internet of Things (IoT) with OJPI. Oracle has introduced the Oracle Java Platform Integrator program to provide partners with the ability to customize Oracle Java Embedded products, including Oracle Java SE Embedded, Oracle Java ME Embedded, and Oracle Java ME Embedded Client, to reach different device types and market segments. Coupled with the massive Java ecosystem of over 9 million Java developers worldwide, this new program will help enable greater development and deployment flexibility for the IoT.

    JAVA ME SDK

    Oracle Java ME SDK is a standalone development environment and a set of utilities for the rapid development of applications for Java ME Embedded. It includes the Java ME Embedded runtime as a device emulation environment for desktop computers. The emulation environment uses the same code base that Oracle licenses to device manufacturers for use on real devices. This enables you to perform extensive testing of your embedded applications on an emulated device before deploying them on a real device.
