Get ready for jBPM 6.1 with a first release candidate

jBPM 6.1 comes with a ton of smaller improvements and bug fixes (done over the last few months on top of 6.0.1.Final), and also includes some important new features, adding to the foundation delivered as part of jBPM 6.0.

Now is the time to give some of these new features a try and let us know if you find some issues or have some recommendations!  6.1.0.Final will be released in the next couple of weeks.

Download here:
Documentation here:
Getting started? Use jBPM installer:

From the release notes, here's a short overview of some of the changes:

Embedding forms in external applications

Now you can embed and run process/task forms in your own web application, that live inside the jBPM console, by just adding a JavaScript library to your webapps. Look at theUsing forms on client applications section in the documentation to see the full functionality and usage examples.

Attaching documents to forms

Added a new widget to forms to manage upload documents and store them on process variables. Using the Pluggable Variable Persistence you'll be able to create your own Marshalling Strategy and store the document contents on different systems (database, a content management system, ...) or use the default demo implementation and store them in your file system.

Web Service (SOAP) interface for remote AP

The execution server, that is part of the jbpm-console web tooling, now also comes with a Web Service interface (in addition to the existing REST, JMS and Java client interfaces).

Deployment descriptors

Deployment descriptors have been added as an optional, yet powerful way of configuring deployment units - kjars. Deployment descriptors allow to configure (among others)

  • persistence unit names
  • work item handlers
  • event listeners (process, agenda, task)
  • roles (for authorizarion - see section 1.5)

Deployment descriptors can be configured on various levels for enhanced flexibility to allow simple override functionality. Detailed definition of deployment descriptor can be found in section Deployment descriptors of the documentation.

Role-based authorization at runtime for process definitions and process instances

The process definition and process instance view in the jbpm console now also take the role-based access control restrictions into account that can be defined on the project the process is defined in. You can limit the visibility of a project (or repository as a whole) by associating some roles with it that are required to be able to see the project (or repository). This can be done when creating the repository, or bu using the command line interface to connect to the execution server. The deployment descriptor (see previous section) also allows you to further customize these roles at deployment time. At runtime, the views will check if the current logged in user has one of the necessary roles to be able to see that process. If not, the user will not see this process or process instance in the process definition or process instance list respectively.

jBPM installer updates

The installer is updated to support:
  • Wildfly 8.1 as application server (note that CR1 still uses AS7 by default but more recently dashbuilder has also added support for WildFly so for the Final release we will switch to WildFly by default)
  • Eclipse BPMN2 Modeler 1.0.2
  • Eclipse Kepler SR2

jBPM Spring integration

Spring integration has been improved to allow complete configuration of jBPM runtime using Spring XML. That essentially means there are number of factory beans provided as part of droolsjbpm-integration module that significanlty simplifies configuration of jBPM. Moreover it allows various configuration options such as:

  • reply on JTA and entity manager factory
  • rely on JTA and shared entity manager
  • rely on local transactions and entity manager factory
  • rely on local transactions and shared entity manager

Details about spring configuration can be found in this article.

Data Modeler - round trip and source code preservation

Full round trip between Data modeler and Java source code is now supported. No matter where the Java code was generated (e.g. Eclipse, Data modeller), data modeler will only update the necessary code blocks to maintain the model updated.

Other

Smaller enhancements also include:
  • Task service (query) improvements, significantly speeding up queries when you have a large numbers of tasks in the database.
  • Various improvements to the asynchronous job executor so it can handle larger loads more easily and can be configured (number of parallel threads executing the jobs, retries, etc.).
  • Ability to configure task administrator groups in a UserTask (similar to how you already could configure individual task administrators).
  • Removed limitation on custom implementations of work item handler, event listeners that had to be placed on global classpath - usually in jbpm-console.war/WEB-INF/lib. With that custom classes can be added as maven dependencies into the project and will be registered on underlying components (ksession).

London Community Event (May 26th - 30th)

During next week a large percentage of the Drools team, some of the jBPM team and some community members will be meeting in London (Chiswick). There won’t be any presentations, we’ll just be in a room hacking, designing, exchanging ideas and planing. This is open to community members who wish to contribute towards Drools or jBPM, and want help with those contributions. This also includes people working on open source or academic projects that utilise Drools or jBPM. Email Mark (mproctor at codehaus d0t org) if you want to attend, our locations may very (but within chiswick) each day.


We will not be able to make the day time available to people looking for general Drools or jBPM guidance (unless you want to buy us all lunch ;)). But we will be organising evenings things (like bowling) and could make Wed or Thu evening open to people wanting general chats and advice. Email Mark if you’re interested, and after discussing with the team, we’ll let you know.

Those currently attending:
Mark Proctor (mon-fri) Group architect
Edson Tirelli (mon-fri) Drools backend, and project lead
Mario Fusco (mon-fri) Drools backend
Davide Sottara (wed-fri) Drools backend
Alex Porcelli (mon-fri) Drools UI
Michael Anstis (thu-fri) Drools UI
Kris Verlaenen (wed-thu) jBPM project lead
Mauricio Salatino (mon-fri) jBPM tasks and general UI
Jeremy Lindop (wed-thu) jBPM designer (new hire)

Embedding process forms in your application

Pere has shared some details on a new feature he's working on for the jBPM 6.1 release, i.e. the ability to embed a form (to start a process or to complete a task) as part of your own application.

With jBPM6, a new form modeler allows you to graphically design your process and task forms (using a WYSIWYG style of editor, dragging an dropping text fields, labels, etc. to create your form).  These forms are then used in the jbpm-console to typically ask the end user for input (when you start a process or complete a task).

For example, this form was designed to allow users to request a mortgage by starting the mortgage process.



Pere is developing a simple REST service that will generate a URL that you can use to show the form (that you designed as part of the process) in an iframe in your own application as well.  It also includes a simple JavaScript API you can use to communicate with the form.

Keep an eye on his blog, as this is just part 1, more details to follow.  Feedback welcome.

Webinar (April 10th): Business Process Simulation

Get More Value out of BPM with BPSim Simulation

BPSim

Thursday, April 10th, 11:00AM Eastern

Business process design with BPMN2 can be complex, with many feasible options for implementing a business strategy. How can process designers evaluate alternative approaches before committing to a costly rollout of an untried process design?

Recently, there have been great strides in new process simulation tools, intended to answer this question and help analysts optimize their process designs before any real data is available to test them against. The BPSim standard is now emerging to provide a common framework for defining and exchanging simulation data in conjunction with BPMN2 models.

Join BPM.com's Nathaniel Palmer with guest Kris Verlaenen to learn how BPSim compatible tools can help you understand how business process designs will perform in practice, and where to look to improve and optimize them.
As part of the presentation we will see a live demonstration of Red Hat's new process simulation tool, included with JBoss BPM Suite. Attendees will also receive access to the developer version of BPM Suite, and the exclusive demonstration models used in the presentation.

Why You Should Attend:
  • Learn How to Use Business Process Simulation for Data-Driven Process Excellence
  • Gain Both Actionable Ideas and a Complete Working BPM Suite with Process Simulation Capabilities
  • Jumpstart Your BPM Programs With Pre-built and Ready-to-Run Simulation Models
Who Should Attend:
  • Business Architects and BPM Practitioners Looking to Get Started with Process Simulation
  • Business Analysts Seeking to Leverage BPM and Simulation for Data-Driven Process Optimization
  • Anyone Looking to Get Started with BPM, BPMN2 Process Modeling, or Process Simulation
