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? A framework to build RESTful Web Applications on top of the Nuxeo Platform. ● Features ● Built on top of JAX-RS model. ● Content Management through Nuxeo Platform ● Full Groovy scripting support ● Hot Deploy of Web Modules. ● Flexible Template Model - based on Freemarker ● Embeds GlassFish v3 as an OSGi bundle.
