Hi, recently I've begun working with the latest version of Liferay. I’m interested in the development of portlets that make use of the integrated jBPM workflow of LifeRay, but I don’t find any documentation.
In the previous version (5.2.3) there are web plugins for the ESB (Mule o ServiceMix) and for the jBPM implementation of workflow engine. Both of them provides a BPM service for portlets.
In the current version, is there an ESB? Can I use the LifeRay integrated workflow from new custom portlets? Or, the LifeRay integrated workflow is only usable for web content and document library?

Thanks in advance.

We do not bundle an ESB, but you can use Mule or ServiceMix.

While 6.0 will support jbpm3.2 as a workflow option, by default we will ship our own workflow. It does not have all the capabilities of jbpm (e.g. condition nodes, etc), but it will contain the primary features needed for human workflows. You may use either (workflow engines will swap automatically similar to how the search engine adapters work).

You can use the embedded workflow for custom portlets. You'll have to do so via the interfaces defined in com.liferay.portal.kernel.workflow.*

Initially, for 6.0, workflow will be document library and web content. For 6.1, we currently plan to add this across other portal assets. The goal is to allow workflow control via the same task console and workflow console for any assets deployed to the portal.

Ok, thanks for the info, but I would like to know more about the Liferay's workflow engine, is there any information resource available about Liferay's workflow engine?

We are still busy with the final implementation details, but you can see the XSD in trunk today (liferay-workflow-definition-6_0_0.xsd. At present, we are supporting the normal following types of nodes:
(1) State
(2) Fork
(3) Join
(4) Task

Actions are supported for each type of node (both onEntry and onExit). Instead of being Java code, actions are expressed in a scripting language (e.g. Javascript, Ruby, Python, Groovy). In the action script, you will be able to available Liferay APIs.

Michael,

I would like to test workflow in LR 6.0.1. Do you have any suggestion on where I can start?

Any documentation, link, or name of the java class I can read will be appreciated.

Hi Michael.

I was playing around with Liferays workflow portlet (using KaleoWeb) using Liferay 6.0 RC2.
My main question is, wheter it is possible to scope workflow definitions more fine granular.
E.g. i got a single approver workflow for web content.
Now i want to achieve that web content has different reviewers relying on its category.
Is that something that is possible within liferays (or jbpm) business logic?
I'm thinking about something like...:
1) ordinary start state
2) Conditional transitions, evaluating the category of the web content
3) now different tasks with different swimlanes, the lanes defining the reviews via group id.
4) ordinary approve / reject

So the only thing i'm not sure if it will work is point 2, as i'm not sure how/if it's possible to check the web content category via condition.

Anyone could confirm my approach might work or if there's a more smart solution?

Kind regards,
Christoph

Hi!
In Liferay 6 neiver Mule nor ServiceMix is required to work with jBPM.
Liferay now has own workflow API and several implementation (kaleo and jBPM3 based). As well as it is possible to implement own (for example some time ago I've started jBPM4 based implementation - but should place it on hold due to time limit).

Hi Alexey,

thank you for your clarification.
I managed now to get jbpm3 running with Liferay 6.0.3GA.

As well i managed (with jbpm) to basically realize the scenario i described earlier by writing my own DecisionHandler that returns the transition name conditional to the category of an asset.

EDIT: Finally decided to write my own assignment handler to be more flexible and have no need to adapt the workflow if categories are added.

Kind regards,

Christoph

Has anyone attempted to integrate Servicemix 4 with Liferay 6 yet? We are actively using Servicemix 3 with Liferay 5.2.3 with no issues.

Hi!
If you got sources of jbpm-web, you should be able to build sample process-definition with using ant build-samples - it will place sample par (Process Archive) file into samples folder - that par need to be deployed into Liferay.

You may be also interested in jbpm4-web plugin - provided same functionality (but with using newest jBPM4.4 version) or activiti portlet (integration of Liferay with Activiti workflow engine).
Both are not in final state - but quite usable.

jBPM4 support: http://www.emforge.net/web/jbpm4-portlet
Activiti Support: http://www.emforge.net/web/activiti-liferay

Hi everybody,

Could anybody please direct me to any documentation on Liferay 6 and jBPM 3 integration?
What are the initial steps to be carried out?

What is the location of jBPM 3 in Liferay SVN? Also, how does one build it? I'm using Fedora Core 11.

I'm new to Liferay and exploring workflow in Liferay 6 right now... Specially focusing on jBPM 3.

Thanks!
