3. In this tutorial you will
o LEARN what modern server applications need
to feature
o UNDERSTAND the usage of selected EclipseRT
technologies
o BUILD an EclipseRT server application based
on Equinox and Eclipse Gyrex
o SETUP a private cluster connecting all
attendees
Tutorial: Dynamic Server Applications with EclipseRT Gunnar Wagenknecht, Andreas Mihm, Jochen Hiller

4. Modern Server Application
Requirements
Million
o Support high traffic use cases transactions
per hour
o Support different frontend
technologies and devices
o modular in development and deployment
o Easy to setup
o Open for new technologies  easy to extend AND to
shrink
o e.g. persistence

5. Eclipse RT
“EclipseRT is the collection of OSGi-based runtimes and frameworks built
by the Eclipse open source projects. “
Containers, Middleware, EnterpriseFrameworks
Tutorial: Dynamic Server Applications with EclipseRT Gunnar Wagenknecht, Andreas Mihm, Jochen Hiller

6. Equinox
o reference implementation for OSGi spec
o foundation of EclipseRT
o component oriented development and assembly
Tutorial: Dynamic Server Applications with EclipseRT Gunnar Wagenknecht, Andreas Mihm, Jochen Hiller

7. Eclipse jetty
features
o Asynchronous HTTP Server
o Standard based Servlet Container
o Web Sockets server
o Asynchronous HTTP Client
o OSGi, JNDI, JMX, JASPI, AJP support
Small foot print allows large scaling
Jetty runs in
o Apache Hadoop
o Google AppEngine

9. GYREX
lightweight application stack for building server
applications using EclipseRT technologies.
o built-in clustering
o built-in web-based administration UI
o built-in multi tenancy
o enhancements for professional maintenance
- centralized logging
- cluster provisioning UI
