J2ME 主要针对嵌入武类电子设备,是一种高度优化的Java运行环境.它是Java 2的一个组成部分,能够将Java语言与平台无关的特性移植到小型电子设备上,允许移动无线设备之间共享应用程序.而嵌入式系统如今发展越来越迅速,凭借嵌入武操作系统进行各个开源软件在嵌入式平台上的移植操作,发挥其更强大的软件系统功能.将这两种现在比较流行的技术结合起来,即以phoneME这款开源的J2ME软件作为研究对象,通过搭建交叉编译环境和Qtopia库等相关基础配置,将其移植到 ARM 嵌入式 Linux 系统上.之后通过运行多个 MIDlet 应用完成了相关的测试和验证.%J2ME is a high optimal Java platform designed for mobile devices and embedded systems. It is a part of Java 2 , and can transplant the Java's cross-platform feature to the embedded devices, then provides shared applications among the mobile wireless devices. On the other side, with the rapid development of the embedded system,lots of open-source softs are transplanted to the embedded platform by its embedded operating system, and more software system functions are developed. This article combines above-mentioned two popular technologies. After the cross-compile environment and Qtopia library built, it transplants phoneME which is a famous open-source J2ME platform soft onto the embedded Linux. Then according to run some MIDlet applications, the system is verified correct and effective.
