ActiveBPEL, LLC is an open source software organization that licenses and distributes the ActiveBPEL™ engine technology. The ActiveBPEL engine is a robust runtime environment that is capable of executing process definitions created to the Business Process Execution Language for Web Services (BPEL4WS, or just BPEL) 1.1 specifications.
The ActiveBPEL engine technology is developed and maintained by Active Endpoints, Inc. (AEI), which also uses the same technology in some of its commercial products. AEI created the ActiveBPEL open source project because AEI believes that the open source model is an effective means through which to foster community interest, education and development around the BPEL standard.
Key benefits of using ActiveBPEL engine technology include:
Completeness. The ActiveBPEL engine comprehensively implements the BPEL4WS 1.1 spec including the full complement of BPEL activities, event handling, exception handling and scope/compensation management.
Industrial Strength. In addition to comprehensive BPEL 1.1 support, the ActiveBPEL engine includes high-end features like deployment packaging, process persistence, event notifications and console APIs.
Growth Track. As a distributor of commercial products based on the ActiveBPEL engine, AEI is committed to the ongoing development of ActiveBPEL technologies. The ActiveBPEL open source project will continually benefit from the contributions of both AEI and the ActiveBPEL community at large.
