what (the hell) is this talk about?!?

luckily no horoscopes!

OSGi for the earthlings: Meet Eclipse Libra

EclipseCon 2010/2011, JavaOne 2011/2012

Eclipse Gemini

Eclipse Virgo


so what (the hell) is OSGi?!?

architecture for developing and deploying modular apps

build using OSGi apis

deploy to an OSGi container

a dynamic modular runtime for Java developers


containers?

from Symbian to Enterprise

equinox

felix

knoplerfish

µJonas

tools

Ant tools: bnd, Bundlor

Eclipse plugins: bnd, Bndtools, Bundlor, Pax, Sigil, Concierge

Rational

Spring Tools (Eclipse Virgo)

back to 2009

later...


problems!!

development complexity, no more plain java (bundles, activators, manifests...)

different tools, adds its own behavior and complexity (ant, maven, packaging..)

different containers, different packaging and configuration


the (OSGi) Developer

need the learn the OSGi way, well it is a new platform...

need to learn each tool

need to know each container

pointed ears

science officer

half human - half vulcan

trying to understand

human nature

rounded ears

developer

java & OSGi

trying to understand OSGi


there used to be a similar problem!!

Building Java Web/J2EE apps!

Different vendors

Different servers

Different configurations

Different tools

Did old Java Web/J2EE apps were really portable?


So what happened?!?

Eclipse Web Tools Platform

abstraction of runtime from the project

adapters for the runtimes to integrate the IDE

target platforms for the runtimes

the wheel?


road to Libra... OSamI

sorry, not a japanese beer

targets social needs: energy efficiency, remote health, smart home, mobility..

based on OSGi

first results: Green building (grenoble, thales, bull), Smart Home (VTT), Mobile (Siemens), Embedded (ProSyst)


OSamI Tools

OSamI tools for OSGi developers

abstraction layer between bundles and containers

built on server adapters (well OSGi runtime adapters)

demo at EclipseCon 2010

moving to Eclipse repo... (2011)


PDE to OSamI

Extend PDE

Not only Eclipse plugins (PDE)

Support for multi OSGi frameworks

Runtime independant projects

Runtime instances


Eclipse Libra

tools for creation of deployable artifacts for application servers implementing the OSGi Enterprise specification, (Web Application Bundles)

tools for converting Java EE deployable artifacts to OSGi Enterprise deployable artifacts (Dynamic Web projects to a Web Application Bundle projects)


Eclipse Libra (cont.)

tools for editing and validation of the metadata of OSGi Enterprise artifacts, (extension of the PDE Manifest Editor for editing manifest headers)

OSGi server adapters, providing basic implementation of configuring an OSGi-based application server, starting it and deploying OSGi enterprise artifacts.


Libra in a Nutshelladapters for OSGi containers

no runtime info in bundles

dynamic packaging, deploy, run, debug

easy to develop new adapters

war products (packaging OSGi container with bundles as a war file)

gemini profile (OSGi web profile)


demosIf I fail... go watch it online...

http://www.eclipse.org/libra/documentation/video/




Eclipse Gemini

Modular implementations of JavaEE

each project can be used on its own, combination with others or with any OSGi bundle.


Gemini Blueprint

Reference implementation of OSGi 5.0 Enterprise spec

Originally called Spring DM


Gemini Management

JMX management model from OSGi 4.2 spec

Administration of OSGi runtime, bundles, services via JMX


Gemini DBAccess and JPA

Modularized OSGi distribution of JDBC drivers

Drivers can be packaged seperately from bundles

JPA on OSGi


Gemini Web

Reference implementation for running enterprise web applications within an OSGi framework.

Just create a Dynamic Web project and add OSGi web profile.


demo


Eclipse Virgo

OSGi based, Java Application Server (originally Spring DM Server)

based on Equinox and Tomcat servlet container

supports: OSGi bundles, plain java web apps, shared lib wars, shared services wars


Virgo FeaturesWeb admin console

Gogo shell: command line via ssh or shell

Plans: scopes, lifecycles

Provisioning: dependency resolution on local or remote repos

Web container: for plain wars

Spring3, Hot deploy, Logging...
