• W ebSPhere sMash Strategy • JSON/ATOM support
– Embed in products including Process Server/ Enterprise Service Bus • SCA HTTP Imports/Exports,

23. Sample: Rapidly Expose Data RESTfully
Enable Developers With A Simple Programmatic And HTTP Data API
WebSphere sMash application
Access REST resource
/app/resources/
through AJAX
employees.groovy
ZRM.delegate()
Database
/app/models/
employees.json
Model application data
• Constrained set of APIs encourage a RESTful application
architecture
• Data model that maps well into Atom feeds and JSON
formats
• Robust framework for persistence, validation, and
Access resource data with Dojo serialization

24. Light-weight Flow in WebSphere sMash
• Assemble Flow is target to compose application with the
flow pattern by “wiring” activities.
<process name="sortSample" persistPolicy=“off">
• <receiveGET name="rssRcv"/> model and engine
Light-weight flow
<feed name="YahooFeed" url="http://rss.news.yahoo.com/rss/topstories"/>
<feed name="CNNFeed" url="http://rss.cnn.com/rss/cnn_topstories.rss"/>
<aggregateFeeds name="aggregate">
<input value="${YahooFeed}"/>
<input value="${CNNFeed}"/>
</aggregateFeeds>
<sortFeed name="sort" orderBy="-published">
