The implement of JAVA API for supporting the embedded system is capable of developing the object oriented system with code reuse because the developer is able to use JAVA in the embedded system. The system dependant parts for implementing JAVA API are realized from a native function. In this paper, we devide JAVA API into the platform-independent JAVA part and platform-dependent native part for the implementation of JAVA API to manage the linux based embedded system devices, and focus on the control of the embedded system devices using JAVA API.

임베디드 시스템을 지원하는 JAVA API를 개발하면 임베디드 시스템을 개발자가 JAVA를 사용하므로써 코드의 재사용, 객체지향 개념의 시스템 개발들을 가능하게 한다. JAVA API를 구현하는데 있어 시스템에 의존적인 부분들이 존재하게 되는데, 이는 native 함수에서 구현한다. 본 논문에서는 리눅스 기반의 임베디드 시스템 디바이스를 제어하기 위한 JAVA API를 구현하는데 있어 플랫폼 독립적인 자바 부분과 의존적인 native 부분으로 나누어 설계 및 구현하였고, 임베디스 시스템 디바이스의 JAVA API를 통한 제어에 초점을 두었다.

There are several independent applets to support various applications in a Java Card. Each applet in a Java Card processes and manages its own data without concern to other applets and their data. In this paper we proposed file system API to support efficient file management based on Java Card. Also we designed and implemented Java Card based file system API using basic API and referring to the file system standard defined in ISO 7816-4 Smart Card standard. By using proposed file system API, we can replace duplications of same code in each applet with short method call. So the used memory space and processing time is reduced and also the reduction of development time and cost will be expected.

In this paper, we propose an ATM API for Java pplication programming. The proposed Java ATM API is an extended form of java.net package of the Java Core API. Our Java ATM API is defined based on the ATM Forum's semantic standard for native ATM services, "Native ATM Service : Semantic Description, Version 1.0". IN order to provide native ATM services, we defined several new classes within the java.net package, including AtmAddress for AtmAddress, AtmSocket, ATM BLLI and AtmBHLI for Atm BLLI and BHLI information, AtmServerSocket, AtmMulticastSocket, AtmSocketImpl for socket programming over native ATM communication, and AtmConnAttr for native ATM connection characteristics. Software structure for construcing the Java ATM API over Winsock 2 environment and its implementation method are also presented.

The object of this paper is to design a embedded system based on sensor networks. The proposed system can manage the heating by sensing and analyzing the temperature and humidity in apartment house and others. For implementing this system, we devide JAVA API into the platform-independent JAVA part and platform-dependent native part for the implementation of JAVA API to manage the linux based embedded system devices, and focus on the control of the embedded system devices using JAVA API.

본 논문에서는 트랜잭션 기반의 정형/비정형/XML 데이터 관리 및 검색 기능을 갖춘 정보 관리 시스템 KRISTAL-2002를 대상으로 하여, JAVA를 구현언어로 사용하는 개발자가 해당 시스템의 기능을 원활하게 사용할 수 있도록 하기 위한 KRISTAL-2002 사용자 프로토콜 및 JAVA 기반의 API 설계를 목표로 한다. KRISTAL-2002 프로토콜은 TCP/IP 기반 XML 메시징 프로토콜에 기반을 둔 것으로서, 클라이언트와 서버 모두에서 처리 효율을 높일 수 있다. 이러한 프로토콜을 기반으로 3개 그룹에 걸쳐 총 24개의 KRISTAL-2002 JAVA API를 설계/구현하였다.

Many developers utilize specific APIs to develop software, and to identify the use of a particular API, a developer can refer to a website that provides the API or can retrieve the API from the web. However, the site that provides the API does not necessarily provide guidance on how to use it while it can be partially provided in many other cases. In this paper, we propose a novel system JACE (Java AST collocation-pattern extractor) as a method to reuse commonly-used code as a supplement. The JACE extracts the API call nodes, collocation patterns and analyzes the relations between the collocations to extract significant API patterns from the source code. The following experiment was performed to verify the accuracy of a defined pattern: 794 open source projects were analyzed to extract about 15M API call nodes. Then, the Eclipse plug-in test program was utilized to retrieve the pattern using the top 10 classes of API call nodes. Finally, the code search results from reference pages of the API classes and the Searchcode [1] were compared with the test program results.

In this paper, we develop a mobile MAP open API using HTML5 local storage and the W3C geolocation API. The mobile MAP open API consists of the basic JavaScript MAP API, offline navigation API, and multimedia POI (mPOI) API. The basic JavaScript MAP API creates a map and controls, rotates, and overlays data on the map. The offline navigation API is developed using HTML5 local storage and web storage. The mobile web application downloads and stores mPOIs of works of art to local storage or web storage from a web server. The mPOI API is developed using HTML5 video and audio APIs. We develop a mobile art park guidance application using the developed mobile MAP open API.

We developed a Java library Xeni for e-book reader systems on embedded Linux environment. Xeni is an API library providing functions such as rendering for XML-based e-book contents, navigation mechanism for readers and bookmark management. This library is developed in Java language, targeting java virtual machines on embedded Linux systems. We discuss design and structure of the developed library, and introduce the reference implementation of a reader system using this library. Also, virtual machines on Linux environment are briefly surveyed.
