> Can run J2EE applications too
• Open Source> CDDL (like OpenSolaris, NetBeans)> GPLv2 (like Java and NetBeans)
• Enterprise Quality> GlassFish Enterprise Application Server> Adds support, indemnification, and 99.999%
availability

What is Application Server?
• An application server is a server that hosts APIs to expose business logic and business processes for use by third-party applications.
• It provides an n-tier architecture• Often referred to as an J2EE application Server
Application Server flavors?
• WebSphere Application Server and WebSphere Application Server Community Edition (IBM), Sybase Enterprise Application Server (Sybase Inc), WebLogic Server (BEA), JBoss (Red Hat), JRun (Adobe Systems), Apache Geronimo (Apache Software Foundation), Oracle OC4J (Oracle Corporation), Sun Java System Application Server (based on GlassFish Application Server)(Sun Microsystems), SAP Netweaver AS (ABAP/Java) (SAP), and Glassfish Application Server.

Clustering in GlassFish v2
JMX = Java Management Extensions
Out of the Box
●Full Clustering?●Let's create one● 1 Install GlassFish with cluster profile● Create a Domain Admin Server● Create a NodeAgent 1● Create Instance 1 & Instance 2● Deploy a sample app with session state● Test Cluster

GlassFish v2 for the Developer
• Single, smaller, download> Around 60 MB total>
• Multiple User Profiles> Developer, Cluster, Enterprise> Upgrade from one to another>
• Better startup time> Almost matches Tomcat> (see also GlassFish v3)
• Cool Technologies> Grizzly's Comet, jRuby> on Rails, jMaki, …>
• Update Center> Provision and install new> features, frameworks, …>
• Tools support> NetBeans, (My)Eclipse,> IntelliJ, etc...
Java EE 5 = (J2EE 1.4).next
• Java EE 5 Theme: Ease of Development• POJO-based programming
> More freedom, fewer requirements• Extensive use of annotations
> Reduced need for deployment descriptors> Annotations are the default
• Resource Injection• New APIs and frameworks
GlassFish
Developement Made Easy
Out-of-the-Box Support• Latest Java EE specification• Integrated with NetBeans (and Eclipse bundle)
> More freedom, fewer requirements• Key technologies, including:
> Java RMI over internet inter-ORB protocol (RMI-IIOP)> J2EE Connector Architecture and Java Messaging Service (JMS)> Enterprise JavaBeans (EJB) 3.0 specification
• Implements Java Management Extensions (JMX) & application server Management Extensions (AMX) API
• Custom managed beans (Mbeans)• Representation State Transfer (REST) web services
Enhanced Developer Productivity• SOA features and web services, including web services
management• Annotation for rapid development and deployment of enterprise
applications• Simplified deployment and execution of enterprise applications
by integrating with Java Web Start• The incorporation of run-time performance improvements and
new technologies• Database connectivity to Oracle, Sybase, IBM, Microsoft SQL,
MySQL and Derby• Enhanced and easy web-based administration, as well as full
administration from a command-line interface
Easy of use• Update Center
JBI support
Enterprise Integration
JBI – A Universal Plug 'n Play Layer● A standard way to add new
functionality to an existing platform
● Standard Installation and life cycle for components
● Standard WSDL based communication across components
● Standard deployment model for all components
● Result of the experience we had with our own Products: Integration Server EAI, SeeBeyond ICAN

• Message payloads are opaque data sent along to the receiver (no canonicalization)

Java EE 6 – JSR 316
• Extensibility• Profiles• Pruning• More ease of
development
• New and updated:• JSF 2.0 (JSR 314)• JSP 2.2• JAX-RS (JSR 311)• WebBeans 1.0 (JSR 299)• Servlets 3.0 (JSR 315)• EJB 3.1• Java Persistence 2.0• JAX-WS 2.2• Java EE Connectors 1.6
Goal is to deliver a final version first half of 2009The exact set of technologies to be included will be determined by the expert group
RightsizingRightsizing
Java EE 6 – Enhancements• Servlet 3.0
> No more web.xml editing> ARP (Async. Request Processing)> File upload
• JPA 2.0> Criteria API> Collections and better Maps support> Validation support (JSR 303)> @OrderBy, specify unfetched state
• JSF 2.0> Make custom components much easier to develop > Ajax support, less config., align w/Portlet 2.0, Facelets
Java EE 6 – EJB 3.1• Packaging simplification
> No more ejb-jar. Easier to share libraries, persistence units• Singleton Beans
> @Singleton to share data in EJB container (per JVM)• Concurrency
> @ReadOnly as singleton optimization (vs. single-threaded)> @BeanManagedConcurrency for explicitly synchronized
• TimerService> @Schedule(hour="12",dayOfMonth="2")
> Automatic creation (on deploy)• Asynchronous operations
> @Asynchronous public void init (...) { ... }> @Asynchronous Future doWork (...) { ... }
Java EE 6 – New APIs• Web Beans 1.0
> Brings together JSF and EJB> Inspired by JBoss' Seam
> JBoss (Gavin King) is spec lead for JSR 299> Bob Lee (Guice) heavily involved
• JAX-RS> RESTful Web Services> RI developed in // with Spec:
http://jersey.dev.java.net> Expose POJO as RESTful resources> High-level declarative programming model> Flexible typing, runtime does common conversions> Pluggable types, containers, and resolvers
GlassFish v3
• Fast startup• Modular (OSGi), extensible architecture• Dynamic resource and runtime loading• Build-your-own runtime• Not just Java
> Ruby on Rails, Grails, PHP, Python/Django, Scala> Leverage performance, admin, monitoring, clustering
• Preview available now (TP2)> Final in 2009, possibly a web tier in 2008> Aligned with Java EE 6
GlassFish v3 (cont.)
• OSGi: Apache Felix as default• 21 MB download, 1-sec startup• Admin and update tool downloaded on demand• Add-ons available from update center :
> EJB 3.1 (preview)> jRuby On Rails (no WAR packaging required)> Grails (now also for GlassFish v2)> Jersey and Metro (Web Services)> jMaki (Ajax)
• Tools-ready: NetBeans 6.1, Eclipse 3.4• Embedded GlassFish API
