摘　　要：随着基于构件开发CBD(Component-Based Development,CBD)技术的发展,嵌入式领域的工程师也使用这种通过有计划地集成现有软件构件的方法来进行开发。本文首先给出了构件的描述性定义,即构件是一个独立发布的功能部分,可以通过它的接口访问它的服务。然后研究了Java的软件构件JavaBean和在嵌入式系统上的构件模型J2ME(JavaTM2Micro Edition,J2ME),分析了JSR82蓝牙协议栈的层次结构,并介绍了基于JSR82实现蓝牙通信的btMIDlet.java、btServer.java和btClient.java这三个源程序的主要功能和几个重要的方法。最后,给出如何在Linux下建立交叉编译环境,并把编译生成的内核vmlinux.out和272K的java虚拟机KVM(Kilobytes Virtual Machine,KVM)移植到OMAP1510芯片以便运行程序。With the development of CBD（Component-Based Development） technology, the engineers working in the embedded areas develop by using the method which integrates designedly the existing software components.Firstly, this paper presents the descriptive definition of component.A component is a functional unit of independent release and its services are accessed through its interface.Secondly, it researches the Java software component JavaBean and component model J2ME（JavaTM 2 Micro Edition） in embedded system, analyses the structure of the JSR82 bluetooth stack , and also introduces the main function and several methods of the bluetooth communication programs which are implemented based on JSR82 and composed of btMIDlet.java, btServer.java and btClient.java.Lastly, it tells how to build cross-compiling environment on Linux and how to port the compiled kernel vmlinux.out and the KVM（Kilobytes Virtual Machine） which is 272K to the chip OMAP1510 for running the programs.
