An Environment of the Hyper Dictionary

The Hyper Dictionary runs using several kinds of technology.

Operating System	RedHat 9.0
JAVA Version	J2SDK1.4.2
Web Server	Apache2.0.47
Servlet Container	Tomcat4.1.27
RDB Server	MySQL4.0.16
JDBC Driver	mm.mysql

• The Base of the Hyper Dictionary

The base of the Hyper Dictionary consists of RedHat Linux 9.0 and JAVA language.

• Web Server: Apache

Apache is Hyper Text Transfer Protocol (HTTP) web server software based on The National Center for Supercomputing Applications httpd Ver.1.3, and it is a free and open source. Although Apache is free software, it has high reliability and many functions, and it is said that the reliability and functions are not inferior to those of business web servers, such as the Microsoft Internet Information Server (IIS) and the iPlanet Web Server. Also, Apache has the best share of web servers all over the world.

• Java Source Pages (JSP)

JSP is text documentation which produces responses to user's requests from set protocols such as HTTP. It is mainly used to build web applications. The construction of JSP is that particular tags for JSP were embedded in Hyper Text Markup Language (HTML). The JSP container interprets these tags, and dynamic HTML pages were generated.

• Servlet

Servlet is a technology which builds dynamic contents. It is a class of JAVA, and the class possesses a function which manages requests from HTTP and sends responses.

• Servlet Container: Tomcat

Tomcat is an openly developed web application server which runs Java servlet and JSP on a server machine. Sun Microsystems and Apache Software Foundation developed it together, and it is a reference implementation for Java 2 Platform Enterprise Edition, which is a platform in server side Java technology of Sun Microsystems.

• RDB Server: MySQL

MySQL is the most popular open source Relational Database Management System (RDBMS) which is faster at searching for data than other RDBMSs in business. Also, that MySQL can accommodate to several platforms such as Unix, Linux, Microsoft Windows, Sun Solaris, Mac OS, and FreeRSD is an advantage.

• JDBC Driver: MySQL Connector

Java Database Connectivity (JDBC) is an Application Program Interface to access RDBMS from Java programs. Programs which are independent of the kind of database can be developed, but a driver adapted to each database must be introduced to that system in order to actually operate the JDBC. The driver is the JDBC Driver.[10][11][12][13]
