Windows workflow is an excellent framework for implementing business processes. One thing that is missing in it is direct support for human activities. Several approaches to solving this problem exist, but they are not generic enough for general usage. In this article we will define one of the approaches to a completely generic implementation of human activities in WF.
Although OMG is not scheduled to get to BPMN 2.0 until August/September timeframe, the initial announcements about its possible directions have caused a lot of activities on the Web.
JBoss is close to releasing version 1.0 of their "Process Virtual Machine", an ambitious project that seeks to provide a definition language agnostic process execution engine. InfoQ spoke with project lead Tom Baeyens about the project, and how the PVM changes the BPM landscape.
In another one of our semi-regular Virtual Roundtables, InfoQ took the opportunity to talk to some of the main authors behind the BPEL4People and WS-HumanTask specifications and find out the driving forces behind it and what we can expect next.
OSWorkflow by Diego Adrian Naya Lazo discusses the open-source OSWorkflow, a Java-based workflow engine. As described on the official website, "This book covers all aspects related to OSWorkflow. No prior knowledge about OSWorkflow is needed". The book's publisher, Packt Publishing, also provided InfoQ with an excerpt from Chapter 4 of the book, entitled "Using OSWorkflow in your Application".
BPMN's adoption is increasing rapidly. In this post, we review some recent activity such as the publication of BPMN 1.1 by the OMG, a tutorial on how to use the Eclipse SOA Tools Platform to "Execute Business Processes" and a comprehensive 120 minute tutorial on BPMN by Bruce Silver.
Initially released in 2000, Flux is an embeddable Java software component for Java development teams who need job scheduling, file transfer and workflow management. Flux 7.7 extended the product's secure file transfer capabilities and increased the scalability of the Operations Console. InfoQ discussed with David Sims, Flux President about the new features and other product developments.
Tom Baeyens wrote a summary of the state of Workflow & BPM standards and tools. After a detailed look at BPEL, BPMN, and other technologies such as choreography, XPDL, BPDM, jPDL, Tom takes the stance that it is time to abandon the idea that non-technical business analysts can draw production-ready software in diagrams and separate the analysis process models and executable process models.
Paul Haley, rule technology visionary, discusses criteria for choosing rule engines versus procedural code in business process solutions, as well as examining the current state of BPM/BRM integration.
In a new InfoQ article, Jean-Jacques Dubray explores a new architecture blueprint for BPMSs that offers a cleaner alignment between SOA and BPM. Jean-Jacques argues that after more than eight years of intense research, we are still far from having the ability to use the business process models designed by business analysts to create complete executable solutions.
Intalio last week released their open source based BPM System - Intalio|BPMS 5.0, including amongst other things a BPMN Editor and a BPEL server engine. The release is a milestone for Intalio in their effort to realise a complete solution for their BPM 2.0 vision. InfoQ took the opportunity to interview Ismael Ghalimi, Intalio CEO, and Arnaud Blandin, EMEA Director, about the new release.
JBoss Drools, an open-source business rules engine, recently reached version 4.0. InfoQ took the opportunity to learn more about JBoss Drools and its current and future capabilities.
Event Driven Architecture (EDA) is starting to emerge as a good and viable option to build better SOAs. David Luckham recently published a 2 part paper supporting this claim and InfoQ published an article on BI & SOA demonstrating it as well.
Spring Web Flow (SWF) is a framework for modelling and controlling the execution of multi-step work flows in web applications. Flows often execute across HTTP requests, have state, exhibit transactional characteristics, and may be dynamic and/or long-running in nature. In this interview, SWF co-lead Keith Donald talks about how Spring Web Flow works.
A group of several vendors suggests a new WS-* spec that goes by the interesting name "WS-BPEL4People". Compared to WS-BPEL which deals with automated business processes, the WS-BPEL4People spec, which has been under works for nearly two years now, aims to add human workflow capabilities to SOA in general and to the recently approved WS-BPEL 2.0 spec specifically.
