Sun GlassFish WebSpace Server consumes SAW API
By vihangpathak on Feb 13, 2009
Traditionally, performing tasks on multiple portals is tedious and inefficient as enterprises adopt back-end business processes and must then continually manage them. Hence, demand has steadily mounted for the capability to perform tasks on just the portal itself instead of on multiple sites with a single-point solution; that is, a solution that not only handles the process interactions but also enables end users to seamlessly perform tasks as "hooks" in the process. Bear in mind that automation of business integrations requires human steps on portals, often accomplished through proprietary applications. By integrating human workflow into portals, you ensure that all the tasks, whether performed by humans or by software, occur in one place.
WebSpace consumes the SAW API to provide this functionality. The Simple API for Workflow(SAW) is intended to offer a generic workflow api to perform human workflow interaction with various workflow engines. SAW API is an API for performing task management(update(e.g. approve/reject), delete, reassign, escalate etc.) created in a human oriented workflow. The Workflow can be defined in various languages supported by the workflow engines. With SAW API, portlet developers can manage tasks created via various instances of workflow definitions defined in languages specific to Workflow engines.
Currently the SAW API has implementations for Sun Java Composite Application Platform Suite, jBPM, OpenSymphony OSWorkflow.
These implementations are showcased by means of:
- Workflow Portlet available in Portlet Repository(works with saw-impl-jcaps).
- Workflow Portlet available as part of Liferay Plugins(works with saw-impl-jbpm)
- Expense Report Portlet(available as part of eval bundle, works with OpenSymphony os-workflow)
