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?
