Its really exciting to witness how eclipse maturing every year and providing wider set of tools.

Eclipse API helped me to build tools for heterogeneous domains from Database, BPM , Rule Engine, Mashup to Service Component Archoitecture.

Now e4 empowers me to satisfy the growing demand from my clients for web-enabled eclipse platforms in the domains of mashup and soa.

e4 in a nutshell not only relieves you from IDE-ness and typical desktop-centric experiences; but at the same time simplifies UI-development (xml model based widget declaration), supports all types of dynamic languages and RIA (no longer just a Java-rich-client) and finally dynamic deployment on clouds !

Huh ! Its so heartening to see the termonology – ‘Eclipse Application Services’ – in a world turning fast into a Service-only Delivery-channel !

EMF was already REST-compliant and Equinox the perfect OSGi guy !

So what remains is re-organizing eclipse sdk frameworks into well defined RESTful interfaces to make eclipse a set of On-demand offerings !

I hope it will unveil the eclipse super-force and be the strongest weapon in developers armoury.

e4 will provide much-needed upliftment for Eclipse as a common platform for a set of diverse frameworks.

(1) XWT – quickfire design and customization with consistent rendering across platforms and browsers.
So you define your ui-controls (SWT/FLEX/AIR etc.) in ecore model !
e4 will take care of the rest i.e. – Builders will build the controls, bind widgets to layouts and finally javascript-event handlers will be generated to manipulate EMF models (the same way html dom is manipulated in web browser)
Well sounds similar to GWT ! .. but more comforting to hear that we handle EMF model at the end of the day ūüôā

(2) RIA – css support and seamless integration of java-script i.e. support/integrate applications written in java-scripts by compiling them using e4 API dynamically.
e4 provides a Javascript Framework – a standalone bundle in OSGi instance.
JavaScript bundles communicates thru JSON manifest files ! Huh ! .. I am great a fan of JSON ūüôā ..

(2) PAAS – what makes e4 so special is its service-oriented programming model based on OSGi. plug-ins can be reused outside a specific nenviromnet (a limitation in current desktop editions).
No more tight-coupling with Platform, WorkBench, IDE, ResourcesPlugin and JavaCore.

In current eclipse architecture, only OSGi Sevice API and Extension Registry API use – ‘Sevice Programming Model’ – with service locator pattern.

Now in e4 incarnation, what sounds most promising is the SOA implementaion for all types of eclipse frameworks with the full-fledged support for ‘Dependency Injection’
– that means – if I am a client of Widget-service, i don’t need to be aware of the service producer and service broker. Just simply specifying annotations (injection points) widget-services can be accessed and consumed !

Here is a nice blog to get your hand dirty : http://www.vogella.de/blog/2009/08/12/eclipse-e4/

e4 is going to be the single most important thing in an eclipse dedeloper’s life.

Well ! Lets all try out e4 today to unleash the power with eclipse !
