Glossary

Java2

The name Sun gives to Java versions 1.2 to 1.4

JRE

Java Runtime Environment. Required to run Java applications. You need at least this.

SDK

Software Development Kit. Required to write Java applications. It includes the JRE.

JDK

Java Development Kit. Old name for the SDK.

J2SE

Java 2 Standard Environment. The standard version of Java. It either the JRE or the SDK can be downloaded.

J2EE

Java 2 Enterprise Environment. A more complex than J2SE. You don't need it.

 

JVM

Java virtual machine. The core Java engine. The JVM + some libraries = JRE.

Currently all SRC eqSuite Java applications require the Java Runtime Environment (JRE) 1.2 or later.
It is recommended to install JRE 1.4 where possible as it offers speed and quality improvements. Some time in the future JRE 1.4 may become the SRC's minimum requirement.

Where to get Java

The general Sun Web site for Java is http://java.sun.com/.

Windows, Linux and Solaris - J2SE

Windows 95/98/ME/NT/2000/XP, Intel Linux and Solaris J2SE (Java 2 Platform - Standard Edition) can be found at http://java.sun.com/j2se/index.jsp

MacOS

MacOS 9 and earlier do not have a JRE 1.2 available (and never will). Therefore, they cannot run the eqSuite programs.

MacOS X has Java pre-installed. MacOS X will only run on iMacs and other G3 or later Macs.

Other Operating Systems

Other Operating Systems may have a version of Java available.

Look here for Sun's official list: http://java.sun.com/cgi-bin/java-ports.cgi

Is Java already installed on my Computer?

This will work on Windows, Linux, Unix, or MacOS X.

1. Open up a command line.
2. Type: java -version
3. If you get a "Bad command" message then Java is not installed or incorrectly installed.
4. Otherwise you will a message such as: Java version "1.4.1"
5. If the message says a version earlier than Java 1.2, you will need to upgrade.

Installing

MacOS X

Java should be installed by default.

Windows 95, 98, ME, NT, 2000, XP

1. Download the latest JRE (see above)
2. You should have a file named something similar to "j2re-1_4_1-win.exe"
3. Double click on the file.
4. Follow the on screen instructions.
