The Enhydra Shark project delivers a workflow server with a difference. It is an extendable and embeddable Java Open Source workflow engine framework including a standard implementation completely based on WfMC specifications using XPDL (without any proprietary extensions !) as its native workflow process definition format and the WfMC “ToolAgents” API for serverside execution of system activities.
Every single component (persistence layer, assignment manager, etc.) can be used with its standard implementation or extended/replaced by project specific modules. This way Enhydra Shark can be used as a simple “Java library” in servlet or swing applications or running in a J2EE container supporting a session beans API, Corba ORB or accessed as a web service.
Sample ToolAgents are available for many different common tasks in automated workflows.
Storage of process and activity instances is done via a configurable persistence API.
The workflow engine kernel supports configurable LRU caching of active workflow objects for high load scenarios. Caching can be turned off for clustered installations.
The XForms and XSLT based web worklist handler and admin application can be easily adopted to your needs.
In contrast to many other solutions on the market Enhydra Shark gives you the freedom to define your own GUI and to integrate existing systems components of YOUR environment !
