● Products based on Nuxeo EP may be deployed
in several flavors:
● EAR, WAR, RCP or standalone applications.

Nuxeo EP - Requirements
● Applications are made from components.
● Be able to assemble new applications from specific
set of components.
● Be able to add / remove components into an
(optionally running) application.
● Be able to deploy and run modules in any OSGi
framework.
● Provide an extension mechanism for
components.

Nuxeo EP – Deployment

Embedding GlassFish - Why?
● Why Embedding An Application Server?
● Light packaging for enterprise applications.
● Leverage JEE features in standalone applications.
● Powerful component model through HK2
● HK2 is the foundation for GlassFish v3.
● OSGi compatible modules.
● Dependency Injection.
● Lazy Loading – very fast startup time.
● Very easy to embed.

Embedding GlassFish - How?

WebEngine – What Is?

What's next?
● Rewriting Nuxeo micro-kernel on top of HK2.
● HK2 fulfills all the requirements as the foundation
for Nuxeo EP.
● HK2 provides dependency injection and other cool
features.
● Contribute to HK2 an extension point
