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


Modern Server Application Requirements

o Support high traffic use cases

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

Million transactions

per hour


Eclipse RT “EclipseRT is the collection of OSGi-based runtimes and frameworks built by the Eclipse open source projects. “

Containers, Middleware, EnterpriseFrameworks


Equinox o reference implementation for OSGi spec

o foundation of EclipseRT

o component oriented development and assembly


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

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
