GlassFish Server WebLogic Server

Painless Java EE development !
The save/reload paradigm

● Auto-deploy of all Java EE and static artifacts

Session Retention

● Deployment option to maintain stateful
sessions across re-deployments

$ asadmin redeploy --properties
keepSessions=true myapp.war

● Greatly simplifies the
development paradigm

● Integrated in IDEs

Yes, Eclipse too !

Introducing GlassFish Server 3

GlassFish Server Goals
Java EE 6 Themes Oracle GlassFish Server

• Flexibility • Flexibility

• Extensibility • Extensibility

• Developer Productivity • Developer Productivity

• Modularity / OSGi / Hybrid Apps

• Manageability

• High availability clustering

• 24 x 7 x 365 support

3.1 Overview
● Built on GlassFish 3
● Modular and Extensible HK2 Kernel
● ~260+ modules
● Clustering and High Availability
● HTTP, EJB, IIOP, SSO, Metro
● Dynamic Invocation of Services
● End-to-end extensibility

Fast and Furious ...
● 29% better startup/deploy/re-deploy cycle over
3.0.1
● 33% better HA performance over 2.1.1
● Scalable Grizzly Adapter based on Java NIO
●
Full-session and Modified-attribute* scope
● Multiple Standalone instances and Clusters per
domain

http://weblogs.java.net/blog/sdo/archive/2011/03/01/whats-new-glassfish-v31-performance

Modular and Dynamic
● Modular : Apache Felix (OSGi)
● Extensible : HK2
● Yet very Fast !

GlassFish Server 3.1: Deploying your Java EE 6 Applications

More Painless Development
● Fast auto-deploy of all Java EE and static
artifacts
● Application runner
● java -jar glassfish.jar toto.war
● Maven integration
● mvn gf:run, gf:start, gf:deploy, ...
● Containers added dynamically and transparently
● Excellent Tools support

Embedded uses
● Testing
● EJBContainer API (EJB 3.1)
● Simple testing using Java SE (JUnit, Maven, ...)
using EJB container

● Packaging / Bundling
● Beyond the specification: control all of GlassFish
Server with an API = GlassFish Embedded
● Integration testing & ship the server inside the app

What's the deal with OSGi?
● GlassFish Server runs on top of OSGi (Felix)
● Also runs unmodified on Equinox (and Knopflerfish)
● GlassFish ships as 260+ bundles
● Can run without OSGi (Static mode)
● Can use OSGi management tools (CLI or Web)
● Can be installed on top of existing OSGi runtime

● Any OSGi bundle will run in GlassFish Server
● Drop it in glassfish/modules{/autostart}
● Can also asadmin deploy it using --type osgi
● GlassFish OSGi admin console

Extending GlassFish
OSGi-style – an example, a demo and a picture

● OSGi declarative service
● Service-Component
entry in the JAR Manifest
● Invoke the service from a
servlet using standard
@Resource injection
● Never use a GlassFish
API !
● No need to chose
between OSGi and
Java EE

Monitoring and Management
Beyond web console and asadmin
● Dynamic and non-intrusive monitoring
● BTrace integration
– Portable, dynamic and safe tracing tool for Java
– Btrace annotations and API to write scripts
● Java-defined Probe Providers
● RESTful interface
● DTrace for end-to-end
● JavaScript Monitoring tool (add-on)
● Still exposed via JMX
● jconsole and visualvm as natural clients

RESTful admin
● Jersey + Grizzly to provide REST interfaces to :
● Configure runtime (via GET, POST, DELETE)
● Invoke commands (restart, stop, deploy, etc..)
● Monitoring (GET only)
● Available from :
● http://localhost:4848/management/domain
● http://localhost:4848/monitoring/domain
● Use REST clients as Admin GUI substitute
● Use your favorite glue/scripting language or tool
● Data offered as either XML, HTML or JSON
● Extensible

More GlassFish Server 3.x
● Developer performance
● Embedded API
● RESTful API
● Update Center
● Metro 2.0
● OpenMQ 4.x
● Admin console
● Btrace monitoring
● ...

Developer Highlights
● Developer Productivity
● Improved embedded API support
● Updated NetBeans and Eclipse plugin

● Grizzly WebSocket support
● Improved CDI, JSON, hypermedia support in Jersey
● Technology refresh – JSF, CDI, Grizzly, OSGi, JPA,
Jersey, Bean Validation, Metro, UC, etc.
● Implementation of various Enterprise OSGi Specs

Clustering Highlights
● HTTP, EJB, IIOP, SSO, Metro

● New - RM Sequence, Secure Conversations
● Session-based replication using Shoal
● Distributes session state uniformly & consistently
among instances
● Shoal OSGi module, loaded when HA-enabled
apps are deployed
● Support for conventional clustering of MQs
brokers in embedded mode

Manageability Highlights
● SSH based remote management and
provisioning
● Application versioning support
● Application scoped resources
● Statement leak detection and reclaim
● Improved monitoring
● Console based on RESTful API

Application-Scoped Resources
“glassfish-resources.xml”
● Created/deleted with app deploy/undeploy

● Supported in NetBeans

glassfish-resources.xml
java:app/...

glassfish-resources.xml glassfish-resources.xml

Servlet EJB
java:module/... java:module/...

Application Versioning
● Deploy multiple versions of an application, only
one enabled
● Commands
● asadmin deploy foo.war
● asadmin deploy –name=foo:BETA-1 foo.war

● asadmin deploy –name=foo:BETA-1.1

–enable=false foo.war
● asadmin enable foo:BETA-1.1

● asadmin deploy –name=foo:RC1 foo.war

● asadmin undeploy foo:BETA*
● asadmin undeploy foo:*
