Examples On-Demand™ Overview |
Table of Contents
1. Introduction
This document presents an overview of Examples On-Demand™
features introduced in MyEclipse 6.0. To get a better feel
for MyEclipse and learning more about it, please check out our
product

material.
2. What is Examples On-Demand
When learning or evaluating a technology, framework, architectural or design techniques, software developers will tell
you there is nothing more valuable than a working example to
solidify one's understanding of what is required to adopting and
applying that element successfully in his development practice.
To facilitate rapid developer learning, Genuitec has launched
Examples On-Demand, a new web site to provide software developers
a rich and ever growing catalog of ready-to-run example
applications that demonstrate how to quickly and successfully use
popular programming technologies and frameworks, such as Ajax
frameworks, JSP, JSF, Struts, Spring, Hibernate, JPA and
EJB3. Each of the Examples On-Demand example applications
are designed to run directly on the server-sandbox provided in
MyEclipse 6.0 with zero configuration and can be downloaded
directly into MyEclipse 6.0 with a 1-click installation process.
"Show me, don't tell me" is the motto of Examples On-Demand. You can find "How-to" tutorials for every technology and framework available on the web. Yet most provide limited value at best because unless you actually setup development and runtime environments and then implement the typically simplified tutorial examples without flaw, the knowledge gained is mostly abstract, head-knowledge; you can't say with confidence that what you learned will work in practice. Examples On-Demand doesn't just talk about technologies and frameworks but rather it shows you through a wide range of technology, single, and multi-framework examples that download in seconds directly to your MyEclipse 6 workspace and run with 1-click on the MyEclipse integrated technology frameworks and runtime stacks.
Examples On-Demand provides you the "simpler working examples" that Grady Booch talks about in his famous quote "Every complex working application evolved from a simpler working example".
Additional key benefits of Examples On-Demand include:
-
A working example is worth more than a 10,000 word tutorial
- New examples added weekly
- Installs in seconds using Examples On-Demand Browser
- Examples run on the MyEclipse Server Sandbox with zero configuration
- From the insight of running and experimenting with an example developers quickly gain confidence that they can replicate the successful experience in their own application of the same technologies and frameworks
-
Developers can use the Example On-Demand examples as templates
for creating their own
applications
- All example code is open-sourced under the Apache 2 license allowing developers to reuse any of the examples code for their own purposes with no additional open-source requirements
2.1 MyEclipse Server SandBox
All Example On-Demand projects are developed with the goal that they can be run immediately after being added to the developer's workspace without needing to install and configure additional resources (like an application or datasource). This is made possible by the MyEclipse integrated Server Sandbox. The MyEclipse Server Sandbox has evolved with the addition of the MyEclispe Derby Server in the MyEclipse 5.5 release and the MyEclipse Tomcat Server in the MyEclipse 6.0 release. Combined, these two integrated servers provide a complete "out of the box" application development runtime solution for use by example applications.
3. Examples On-Demand Browser
MyEclipse 6.0.1+ provides an integrated Example On-Demand
Browser. The Examples On-Demand Browser is an innovative
application of rich internet application (RIA) technology that
enables you to seamlessly browse online example applications and
then rapidly download, install and run those example resources
from directly within the MyEclipse workbench in a matter of
seconds.
Launch the Examples On-Demand Browser from the
MyEclipse menu; click the
Examples On-Demand menu item:
Examples On-Demand Browser operates directly within the MyEclipse workbench window. When it opens, you can browse the example projects complete with descriptions of their function and the technologies they use.
4. 1-Click Example Download and Installation
If you find an example application that you want to work with, simply click its corresponding Install button. The Examples On-Demand Browser will then download and install the projects that make up the application into your workspace. During the installation process all projects are compiled and validated. Some examples make use of MyEclipse Derby database in the Server Sandbox, so you may see the validation process automatically start the MyEclipse derby database.
Each example project provides a README.txt file in its root directory that provides project details.
Once you have installed an example to your workspace, feel free
to change the source code and experiment with the
application.
Currently, Examples On-Demand projects that
are installed to your workspace are still connected to the
examples.myeclipseide.com public CVS repository. You
can safely disconnect the project from the CVS repository by
going to project
context-menu > Team > Disconnect...
5. 1-Click Example Launch and Test
If the project is a Web Project, you can run it immediately using the MyEclipse 6 1-Click Application Launcher. Right-clicking on the root of the project and choose Run As > MyEclipse Server Application. The 1-Click Application Launcher performs the following operations:
- Packages and deploys the application automatically to the MyEclipse Tomcat Server
-
Starts the server
- Launches a Web Browser opened to the root of the application
NOTE:
If the application you are running requires a database
connection, don't forget to start MyEclipse Derby before running
the example application or you will most likely get a
ConnectionException when the application tries to access the DB
and cannot connect .
After the application is running in the appserver, MyEclipse will open a
Browser View to the home page of your example application. You can
then run your application immediately and even edit it or debug
it on the fly if you wanted.
