Shark is an extendable Java workflow engine framework including a standard implementation completely based on WfMC and OMG specifications using XPDL (without any proprietary extensions) as its native workflow process definition format and the WfMC "ToolAgents" API for server-side execution of system activities. It has well defined client interface, as well as its internal component interface. License: GNU Lesser General Public License (LGPL) Changes: The ExecutionAdministration API was extended to include more options. The FilterBuilder APIs were extended to support more powerful search options. SharkWebClient was refactored to use only Shark's stateless interfaces, and thus to make it possible to use it with Shark deployed as a Web service. Bugs were fixed in the WAPI and XPDLBrowser interface implementations.
