- What is Java?
JAVA is an object-oriented programming language (as is C++). However,
JAVA is platform independent for the most commonly used
hardware platforms, which means it works on a MAC, a PC or a
Unix workstation without modifications. JAVA applets can be run from
a Web page, and Java applications can be installed on the users desktop.
For information about JAVA, see

Java: The inside story.
- JAVA Applets vs Applications vs
JAVA applets are run from a Web
page. Applications are installed on the users desktop and are always run locally.
It is easy and desirable to write applets so they can be installed and used
Script is embedded in a Web page and is not readily
used on the desktop as an application.
- Stability of JAVA
All JAVA developers can tell you about quirks in JAVA. However,
JAVA can not be ignored. Major
software development efforts have invested heavily in Java,
based on it's interactivity on the Web and it's hardware
- Long term feasibility of JAVA
The support for multiple platforms (MAC, PC, Unix, and others too)
makes this an extremely desirable choice for many commercial
and non-commercial software developers. Examples from invited speakers at
this workshop include:
- Uses of JAVA
- Web / Internet / Intranet / Desktop
Java provides a highly interactive
user interface for the Web. In this context, it is useful on the Web, for
both Internet (public) applications and also for Intranet (private, inside an
organization's firewall) applications. Java applets can easily be written
so they can be used as applications on the user's desktop. This is
a very effective method for developing code which can be used in-house
on a user's desktop and also made available to the public via a Web page
as an applet.
- JAVA interfaces to legacy systems
A first line solution for
making a nice Web interface to legacy code.
- All-JAVA applications
For long term, platform-independent
- Current Web pages using JAVA
- Submit your JAVA Web pages to
(Nancy Soreide) to have them added here.
Include: Agency name (e.g. NASA, NOAA, USGS, etc),
1-line description or title, URL.
Desirable to use JAVA DOC to document your code.
- Java Applet Rating Services
Relationship of JAVA to standards
- CORBA / IIOP - Definitions
- CORBA - Common Object Request Broker Architecture
- IDL - Interface Definition Language
- OMG - Object Management Group (Standards organization for
the CORBA model, with membership of over 650 organizations, including
Netscape, Sun, DEC, IBM, Microsoft, etc)
- IIOP - Internet Inter-ORB Protocol
