jBPM BPEL 服务编排（orchestration）语言

欢迎使用 jBPM BPEL 服务编排（orchestration）语言。

BPEL 服务编排的流程语言。由于基于 OASIS 标准，所以它被工业上广泛接纳。通过WSDL接口进行松偶合集成、富流程构造、稳健的错误处理和被清晰定义的可扩展点都是它的突出的特点。

BPEL允许系统集成商得到超出现有更多的价值。新服务能够被作为一个其他服务的功能快速的开发。使用XPath和XSLT能够直接将一个服务的输出转换成另一个服务的输入。而且，内置的分析器允许流程简易的并行执行活动、作用于外部的事件和从例外的条件中恢复流程，所有的这一切全是内置的。

BPEL运行时引擎使用WS-BPEL 2.0 标准和遗留 BPEL4WS 1.1 厂商规范进行编译。这样的话，它就能执行用 Eclipse BPEL 设计器 或任何其他的编辑器编辑的标准 BPEL 文档创建的流程。

Welcome to jBPM BPEL
Service orchestration
BPEL is a process language for service orchestration. It enjoys widespread industry adoption due to its status as an OASIS standard. Loosely-coupled integration through WSDL interfaces, rich process constructs, robust fault handling and clearly defined extension points are among its salient features.

BPEL enables system integrators to get more value out of existing assets. New services can be rapidly scripted as a function of other services instead of being developed from the ground up. Transforming output from one service into input to another service is made straightforward with XPath and XSLT. Furthermore, the built-in constructs allow the process to easily perform activities in parallel, react to external events and recover from exceptional conditions, all within transaction boundaries.

Our BPEL runtime engine complies with the WS-BPEL 2.0 standard and the legacy BPEL4WS 1.1 vendor specification. As such, it can execute processes authored with the Eclipse BPEL designer or any other editor that produces standard BPEL documents.
