Introduction

The Oracle Java ME Embedded version 8 software for the Raspberry Pi platform is a ready-to-run binary for use with an off-the-shelf Raspberry Pi board. The Oracle Java ME Embedded software employs an optimized platform stack for small embedded devices, which includes the Connected Limited Device Configuration (CLDC) HotSpot Implementation (Java Virtual Machine) Version 8, the Micro Edition Embedded Profile (MEEP) application environment, the Generic Connection Framework (GCF) API, and enhanced support for various Java Specification Requests (JSRs).

What's New in this Release

The following features are included in the Oracle Java ME Embedded software:


Note:

This is an Early Access release with a limited scope of features and testing.


Usage Notes

The Oracle Java ME Embedded software for the reference board platform includes an CLDC implementation with a high-performance Java virtual machine that can run IMlets and access input-output ports. This runtime is optimized for the reference board platform.

The Getting Started Guide for the Reference Platform (Raspberry Pi) describes how to install the Raspbian distribution on the SD card, how to connect to the board from the development host computer and how to install, run, and debug IMlets on the board.

Observe the following important notes before running the Oracle Java ME Embedded software on the board:

Installation and Runtime Security Guidelines

The Oracle Java ME Embedded Release 8 EA 2 software installation requires an execution model that makes certain networked resources available. These required resources might include, but are not limited to, a variety of communication capabilities between the product's installed components.

It is extremely important to note that the product's installation and runtime system is fundamentally a developer system not specifically designed to guard against any malicious attacks from outside intruders. Given this, the product's architecture can present an insecure operating environment to the installation file system itself, as well as its runtime environment, during execution. For this reason, it is critically important to observe the precautions outlined in the following security guidelines when installing and running the software.


Note:

The security-related functionality of a final developed application for release into the field is supported by the available components of the Oracle Java ME Embedded software stack incorporated by the developer into the application. The security precautions required by applications in the field are beyond the scope of these recommendations, but must nonetheless be observed by the application developer.


To maintain optimum network security, the software package can be installed and run in a ”closed” network operating environment, meaning the software system is not connected directly to the Internet, or to a company Intranet environment that could introduce unwanted exposure to malicious intrusion. This is the ideal secure operating environment whenever the application under development does not require it.

An example of a requirement for an Internet connection is when the system must communicate with a wireless network over the Internet to fully execute the application under development. Whether or not an Internet connection is required depends on the particular Java ME application running in the development environment. For example, some Java ME applications can use an HTTP connection. If the environment is open to any network access you must always observe the following precautions to protect valuable resources from malicious intrusion:

Security Certificate Precautions

The Oracle Java ME Embedded software distribution bundle contains security certificates that are needed for testing purposes during development of products for final release to customers. Some of these certificates are self-signed security certificates generated by Oracle that are mapped to privileged security domains. IMlets or MIDlets signed by these certificates get high privileges to access restricted APIs, and so these certificates present a security vulnerability if they are released to end users on a customer's device. Care should be taken to remove these certificates after final testing of the product is completed when the product is being prepared for release to end users. This does not apply to certificates issued by universally recognized certificate authorities (CAs), because these are used only for signature verification and do not present a vulnerability.

Developer Agent Precautions

The CLI is incorporated in the Development Agent, which communicates with a device via an unsecured protocol. The Developer Agent is a Java SE application that can be reverse engineered to tamper with or to get information about the communication protocol, which in turn might be used by an untrusted entity to manipulate the device. If you decide to implement the Developer Agent in any product deployment, it is your responsibility to incorporate adequate security measures around the Developer Agent communication channel. This channel uses TCP port 2201 on the Raspberry Pi device for the communication.
