This is the specification of the Java 2 Micro Edition (J2ME) Personal Basis Profile, version 1.0.

Introduction

Personal Basis Profile provides an application environment for AWT-based applications that rely solely upon lightweight components. It provides basic AWT support but excludes support for the AWT heavyweight widgets themselves. This Profile serves as a basis on which user interface libraries such as HAVi UI or other lightweight toolkits may be built, and encompasses the core AWT functionality of the J2ME Personal Profile.

General Requirements

Relationship to Other J2ME Profiles

Personal Basis Profile 1.0 is based upon J2ME Foundation Profile (JSR-46), version 1.0. Specifically, Personal Basis Profile 1.0 includes Foundation Profile 1.0. It is a subset of J2ME Personal Profile (JSR-62), version 1.0. Applications written to Personal Basis Profile 1.0 are therefore upward-compatible to Personal Profile 1.0.

The APIs of the Foundation Profile 1.0 are included here for informative purposes only. (The Foundation Profile 1.0 specification overview is included here.) In the event of a discrepancy, the official Foundation Profile 1.0 specification shall take precedence.

Application Models

This specification defines two application models: Xlet and (implicitly) public static void main(String[]). An implementation of this specification must observe certain application management requirements.

Image Formats

Implementations of Personal Basis Profile must support the following image file formats:

GIF 89a
JPEG using the JFIF file exchange format
PNG version 1.0

Restrictions

Implementations of Personal Basis Profile exhibit certain restrictions relative to the Java 2 Platform, Standard Edition (J2SE). Many of the packages and classes of this Profile are subsets of their full counterparts in J2SE. Additionally, the semantics of the following APIs are subject to mandatory and optional restrictions:

For each optional restriction, an implementation of this Profile describes its behavior by means of a system property.
