Background

Application servers are strategic investments

You are likely to use them for years to come

In the past

J2EE standardSelection based on

-ilities

Maturity

Value-add features beyond the standard

Are you replacing proprietary application servers with open

source application servers (check one)?

8/41

J2EE Didn't Fill the eed

EJB 2 is difficult to use

Many people consider it unnecessary difficult

Entity Beans were especially problematic

But even session beans earned bad reputations

The Open Source community responds

OSS packages mitigating the problem

Hibernate instead of Entity Beans

Spring as a component modelThey were very successful in the marketplace

Many Spring/Hibernate applications

Required only Tomcat to run but also work in full app servers


9/41

When TomcatIs ot Enough

Tomcat doesn't support

JMS

EJBs

Other...

Enterprises need integration

The more mature the app is, the more likely it is to be added

Add-ons

It was possible to add things that Tomcat was missing

But this became a build your own Frankenstein exercise


10/41

Java Enterprise Edition in the Meantime

Weaknesses in EJB 2 model were recognized

Work on new specification was completed

J2EE JEE 5

EJB 2 EJB 3Entity Beans JPA

EJB 3

Simple annotation-based programming model

ot everybody adopted EJB 3JEE will embrace modularity

Profiles, including web profile


11/41

Choices in 2007

Use SpringStart with full app server

Start with Tomcat, build from there

Use EJB 3

Requires full app servers

Full application server

Pros everything you are likely to need, could use EJB

Cons complexity, might use more resources then TomcatTomcat

Pros small, simple, low resource usage

Cons you might need to build your own app server, no EJB


12/41

OSGi

Started in 1999

Recently got a lot of exposure

In particular, R 4.1

JSR-294

OSGi brings

Dependency management and modularity

Ability to load only parts it needs

OSGi currently has a lot of mindshare


13/41

What Does This Mean For Me?

Decisions, decisionsEJB 3 or Spring

Spring on dm Server or on J2EE/JEE server?

OSGi or not OSGi

Do Ineed EJB 2 compatibility?

In addition, there are many old considerations

Servers are not all inclusive

EJB 3 apps won't work on SpringSource dm Server or Tomcat

Contenders

Make a decision about what functionality you need

Evaluate the contenders

JBoss

GlassFish

dm Server

Geronimo

Tomcat


17/41

JBoss

Started in 1999, incorporated in 2001LGPL License

Reasons for Success

One of the first OSS app servers that was proven enough forproduction

Good product

Developers generally like it

Fast startup and operations, easy configuration (for developers)Good standard support

Modular architecture

Possible to control amount of resources used


18/41

JBoss Thought Leadership

Complete ecosystemPortal

ESB

BPM

JBoss has history of innovation

Pioneer of EJB 3

Seam Application Framework

Web BeansOSGi

Support in JBoss 5


19/41

JBoss in Production

DependabilityExcellent clustering and failover capability

Reliable in production

Monitoring and deployment capabilitiesot really oriented toward system administration out of the boxCommand line/file edit flavor of configuration

GUItools (Tomcat manager and JMX Console) are fairly basic

Excellent 3rdparty tools available for monitoring

Hyperic

GroundWorkIT

JO *


20/41

JBoss for Developers

Excellent customizabilityJMX-based, don't deploy what you don't need

Seam is worth a look for developers

JDK with 4.2.3 and 5.0GAJDK 5 compiled binaries work on both JDK 5 and JDK

JBoss IDE

Eclipse-based

JBoss ToolsFree version (RHDS is paid version)


21/41

JBoss - Conclusions

Strengths

Mature, scalable and reliable

Good support for J2EE and EJB 3

Seam framework

Weaknesses

LimitedGUI-based configuration in open source version

LGPL License may be a concern forISV's embedding app servers


22/41

GlassFish

Relatively newLaunched in June 2005

JEE 5 support introduced in May 200

Glassfish 2

September 2007

Clustering and enterprise capabilities

Merged with Sun Java System Application Server

CDDL LicenseHuge interest

First seven months of 2008 - 4.5 million downloads

Compare to Spring Framework's 5 million downloads


23/41

GlassFish Thought Leadership

JEE 5 certifiedReference implementation

Full support for EJB 3

OSGi is coming in version 3

Sun is a strong supporter of OSGi

Good support for dynamic languages

JRuby

GoldSpikeGrails


24/41

Living with GlassFish

IDEetBeans-based

Excellent support forGlassFish

Support for Java for a long time

Sun has fairly large ecosystem (e.g., openESB)

Relatively new

ot as easy to hire expertise

Good production capabilitiesClustering

Failover


25/41

GlassFish Conclusions

StrengthsGood support for emerging standards

Good heritage of code, based on a good application server

Excellent support for dynamic languages

Weaknesses

Less widely used than JBoss

Relatively new


26/41

SpringSource dm Server

ewcomerReleased in April of 2008

GPL license

Incorporates many mature components

Spring FrameworkTomcat

Equinox

dm Server users are very early adopters

Different take on app serverOSGi support

o support for EJB

o JMS out of the box


27/41

dm Server Thought Leadership

OSGi-basedGood OSGi implementation

OSGi discussed a lot in their documentation

o support for EJB

o support for EJB 3 or old EJB 2 spec

Spring offers similar functionality to Seam

Which is somewhat more mature

Although some of the Seam ideas might be somewhat morepowerful

Bijection


28/41

dm Server for Developers

Server works well with Spring Framework

IDE

Spring IDE - IDE for Eclipse platform

Support for etBeans andIntelliJ

OSGi support

Resolves dependency hell

But requires application migration to take advantage of it

Supports Java 5 and


29/41

dm Server - Conclusions

StrengthsSupport for Spring Framework

Support for OSGi

Weaknesses

ewcomer

o EJB

Limited experience among workforce


30/41

Geronimo

Supported byIBMWSCE based on Geronimo announced in October 2005

JEE 5 certified

Full support for EJB 3Apache licensed


31/41

Geronimo Details

CapabilitiesClustering

GBeans andIoC

Built-in frameworks (ActiveMQ, Spring)

Less often used than others (like JBoss) on large

deployments

Certified on Java 5

Works with JavaIDE support

GEP, MyEclipse


32/41

Geronimo Conclusions

StrengthsApache licensed

JEE certified with full EJB 3 support

Sponsored byIBM

Weaknessesot as widely used in production as other servers

Less usage means that it is more difficult to find people whoare experts in it

Smaller ecosystem than others (like JBoss)Although WAS and WSCE share the same name, they do not share thesame code


33/41

Tomcat

First release (3.0.x) in 1999Apache license

Servlet container

Lightweight server

Used in many other app servers

JBoss

dm Server

Geronimo


34/41

Tomcat in Development and Production

Tomcat supportsClustering

Failover

Widely used for both development and production

Supported in most popularIDEs


35/41

Tomcat Conclusions

StrengthsLightweight

Well known and tested

Fast startup/deployment for development

Weaknesses

o support for EJB, JMS or almost anything else outside of

web side


36/41

Conclusions

App servers are not just about the JEE specs

Make some high-level decisions before evaluation

Do Ineed EJB 2 compatibility?

Do I intend to follow EJB 3 and other industry standards?

Do Ineed something fast, lightweight, and easy to use?

Do Ihave a need for lifecycle management of server

components (through OSGi)?

Do Ineed support for dynamic languages like Groovy and

JRuby?

Am Ian early adopter of new technology?


37/41

Recommendations

Im using EJBs andIm conservativeJBoss, GlassFish

Idon't need XA/JMS/EJBTomcat, JBoss, GlassFish, dm Server

Im using SpringConservative - JBoss, Tomcat, GlassFish

Leading edge - dm Server

Ineed to embed an app server in my commercial codeTomcat, Geronimo


38/41

Recommendations (continued)

Iuse Spring heavily andIneed OSGiIneed it today and don't need EJBs - dm Server

Ineed it soon and/or need EJBs GlassFish, JBoss

Iuse Seam

JBoss

Iwant ActiveMQ/Spring/Hibernate preinstalled

Geronimo

Ineed dynamic language supportGroovy/Grails dm Server, JBoss, GlassFish

JRuby/Rails - GlassFish, Geronimo
