Agenda

• The Characteristics of a Development Environment

• Key Developer Concerns• What Next for WebSphere Dev/Test Tools

and Runtime• Demo



The Characteristics of a Development Environment• A rich set of developer productivity tools that

– Make it easy to get started with new technologies

– Assist rapid development for expert users– Provide a responsive environment to test

against– Provide a test environment that has fidelity

with the target production environment



What constitutes “Fidelity”?

• The application programming model available in the Dev Env faithfully reflects that of the production system– Application code and configuration– Application bindings (types, if not values)

• Code that cannot run properly in a production environment shouldbe flagged as such in the test environment

• Ability to test with the same semantic behavior as production system when container-managed QoS is configured.– Easy to test basic function to get it up and running– Easy to engage QoS within Dev Env with same behavior as

production runtime



How is Fidelity Achieved?

Advanced Web, JEE,and OSGi tools

XML, SCA, Batch,Persistence tools

Code coverage, profiling, PD

• By testing on a server type that most closely resembles the production WAS server runtime.



The Development Profile

• By default, WAS servers defined to RAD are configured with a Development profile as the best compromise between fidelity and a responsive test environment

Development Profile

• Optimized for devt activitiessuch as publishing apps• Smaller thread pools• Less resources• Disable activity log• -Xquickstart JVM optionto defer JITing

• Faster server startup• No default apps installed



Frequency of Development Tasks

• Common development tasks include:

• All tasks should be as painless as possible, with special emphasis on the more frequent ones. If the time taken to accomplish these tasks is an impediment to the development, the cost of the fidelity of the test server runtime is challenged.

Hourly

Weekly

Monthly

Frequency

• Modify file within an application• Debug a problem in an application• Restart/redeploy application• Restart server• Share code with team• Change app structure (add/remove a module/bundle)• Make config change• Share config change with team• Reproduce problem from another environment• Upgrade to new service release• Create application• Install server

Developer Feedback

• Developers are looking for more (or less) from the test server runtime in the tools.– Greater test simplicity

• Config model (hard to edit, backup, share)• Admin console is for operational mgmt rather than development• Problem determination (including within customer apps)

– Responsiveness• Incremental publishing, app install, server startup time

– Footprint• WAS server types defined to RAD have a WAS production server

footprint and memory use.– For all types of application

• Tools available only as part of RAD distributions



What Next for WebSphere Dev/Test Tools and Runtime?

WAS V8.5 Alpha introduces:• A new dynamic profile of WAS which is focused FIRST on

the development experience– Small footprint test server runtime– Simplified, shareable config– Fastest possible server start-up

• Fidelity with full-profile WAS– Same containers, QoS as full-profile WAS – But radically refactored to focus on the development experience– Extreme dynamicity to start what the app requires and no more

• Initially focused on dev/test of web, mobile and OSGi apps.

Visit and participate in the new WAS Developer Community

WAS V8.5 Alpha: Introducing WAS “Liberty” Profile• Not a single static profile: rather a dynamic, flexible profile of the

runtime to load only what the application needs– Memory footprint (web feature): < 50 MB– Profile is dynamic – switch parts of the server on and off without

restart.• Extremely lightweight

– Incredibly fast (re)start times: <5 seconds• Simplified configuration for quick time to productivity; one single

config file or modular config (as desired).– Easy to share / diff / manage in version control– Easy to componentize configuration across larger development

teams• Tools available as Eclipse features as well as in RAD…

What This Means For Developers

• Availability of WebSphere Development Tools as Eclipse feature– As an alternative to integration in full RAD– Simple Eclipse feature update for WTP 3.6 (Helios) and 3.7 (Indigo) – Free! No Expiry

• Lightweight WAS Liberty profile runtime for dev/test through new WAS V8.5 Alpha server type in Eclipse– Focused on the development experience– Small footprint test server runtime– Simplified, shareable config– Fastest possible server start-up– Fidelity with full-profile WAS– Free! No Expiry– Initially focused on web apps (including JPA, transactions, security…)

• Accelerate development time to value– Develop/test with WDT and WAS v8.5 Alpha Liberty server type– Deploy applications unchanged to full profile WAS for production



Create a Lightweight WAS Server in WDT

Create a lightweight WAS server configuration in seconds.



Simplified Sever Configuration

• Simplest case: 1 XML file for all server config

• Editable within the workspace

• Exportable, shareable, versionable

No need for Admin Console, wsadmin, or extended EARs

ws-security.xml

server.xml etc.

resources.xml



Simplified Configuration<server>

<featureManager>

<feature>jsp-2.2</feature>

<feature>derby-10.5</feature>

location="tradelite.war" />

<datasource id=“ds" jndiName="jdbc/TradeDataSource"

databaseName="${shared.resource.dir}/data/tradedb"/>

</server>

features control which capabilities (bundles) are installed in the server

'singleton' configurations specify properties for a runtime service like logging

'instance' configurations specify multiple resources like applications and datasource definitions

Any of this configuration could be put into a separate xml file and 'included' in this 'master' configuration file



Flexible Configuration

• Shareable config snippets

<server>...<include url="http://hurgsa.ibm.com/~irobins/

was4d/config/blog.sample.xml" /><include file="${shared.config.dir}/datasource.xml" />

<server>server.xml

• Config can be componentized at any level of granularity, from 1 file to many.– Can use WDT to associate config snippets with a server config.

• Visualization through WDT tools as a single logical view.• Team development: keep the application and configuration

components together.
