The EmbeddedJava TM API is derived from the JDK 1.1 API. The EmbeddedJava platform addresses the software needs of dedicated-purpose embedded devices.
This document describes the facilities that the EmbeddedJava platform provides to applications. It is not a standalone specification because it is based on the JDK 1.1 API. Java APIs introduced after JDK 1.1 will not automatically become a part of the EmbeddedJava API. New Java APIs will be reviewed and evaluated for appropriateness before being added to the EmbeddedJava platform.
The EmbeddedJava API is derived from the JDK 1.1 API. The following definitions describe the degree of API support provided by the EmbeddedJava platform.
The EmbeddedJava platform supports Java standard extensions that are based on JDK 1.1. Java standard extensions have package names that begin with javax. Java standard extensions that are supported by the EmbeddedJava platform are configurable.
The table below describes the EmbeddedJava API by listing the packages available in the JDK 1.1 API and indicating how the EmbeddedJava platform supports each package.
