16 API Support

Oracle Java ME SDK 8 supports many standard application programming interfaces (APIs) defined through the Java Community Process (JCP) program. JCP APIs are often referred to as JSRs, named after the Java Specification Request process. JSRs that are not part of the platform are referred to as optional packages.

The MEEP platform is based on JSR 228: Information Module Profile - Next Generation (IMP-NG).

For a full list of supported JCP APIs, see Table 16-1. Oracle Java ME SDK 8 provides documentation that describes how certain APIs are implemented. Many supported APIs do not require special implementation considerations, so they are not described. For information about Oracle APIs provided to support the MEEP platform, see Oracle APIs.

For convenience, Javadocs that are the intellectual property of Oracle are located under docs in the Java ME SDK installation directory. The remainder can be downloaded from http://jcp.org.

Oracle APIs

The MEEP project type supports developing applications for the Oracle Java ME Embedded 8.0 runtime. The Java ME Embedded 8.0 runtime includes several standard JSR APIs and additional Oracle APIs for embedded use cases. These new APIs are:

Device I/O API: Provides interfaces and classes for communicating with and controlling peripheral devices.
Configuration API: Provides read and write access to the Java ME runtime configuration.
HTTP API Client: Provides a Java-based framework for communication with Web Services.
JSON API: Provides an object model to process the JavaScript Object Notation (JSON) format.
OAuth 2.0 API: Provides access to the OAuth 2.0 authorization framework.

Javadocs for these APIs are located under docs in the Java ME SDK installation directory.
