[jBPM] - Which Designer?

by Franck cdsosi

Franck cdsosi [https://community.jboss.org/people/cdsosi] created the discussion "Which Designer?" To view the discussion, visit: https://community.jboss.org/message/750456#750456 -------------------------------------------------------------- Hi, As said before, I am starting with jBPM. I have several newbee questions about designing business processes with jBPM. I am a bit confused that's why I need help from community ! Which designer are we intended to use ? 1- The one inside eclipse supplied with the 5.3.0 Full Package 2- The web designer also coming wiht 5.3.0 Full Package 3- Use the eclipse BPMN 2.0 Plugin as mentionned in the jBPM User Guide (Chap 10) I want to design first (and then execute if possible) a process with some BPMN "components" such as : Pools Boundary Events Message Flow ... Pools (or Multiple Pools to be more accurate), Message Flows seems to be not available in 1- and 2-. As far as Boundary Events are concerned I thought it was possible to use them inside the web designer as said in http://kverlaen.blogspot.fr/2011/12/jbpm-52-released.html http://kverlaen.blogspot.fr/2011/12/jbpm-52-released.html since I am working with jBPM 5.3. I do not see how to use this functionnality in the web designer... Is it available? The eclipse BPMN 2.0 Plugin seems to offer much more functionnalities for designing processes but if I design with this tool, will I be able to execute it with the jBPM Runtime mainly if I use functionnality not available in standard jBPM designers? What are the best practices according to you?

[jBPM] - jBPM support for clustered application server environment

by Devinder Singh

Devinder Singh [https://community.jboss.org/people/dps_c] created the discussion "jBPM support for clustered application server environment" To view the discussion, visit: https://community.jboss.org/message/750513#750513 -------------------------------------------------------------- Our application runs on webshere application server 7 (JEE5) and has urgent requirement to support clustered environment. That is 2 clones will be running to support our application. We have been using jBPM (with persistence) and during testing ran into a problem with optimistic locking when jBPM request are distributed to different servers. Even during starting any jBPM process, statefulKnowledgeSession.startProcess method call runs into problems because some other clone has potentially updated the SessionInfo. Also for different servers, we're using same SessionInfo id to create StatefulKnowledgeSession instance. Basically, ksession = JPAKnowledgeService.loadStatefulKnowledgeSession(1, kbase, config, env); is used on all the clones. Currently we have two clones, but can have potentially more in future. We're creating StatefulKnowledgeSession during server startup of each node. Code for creating this session is very similar to what's in the jBPM document. In addition, we are also using human task server by using MinaTaskServer, which is also started during server startup. Can the community please suggest some best practices to make jBPM run in clustered environment. Below are some of the links that we have been using but not sure what's the best approach for supporting clustered environment. https://community.jboss.org/thread/195459?tstart=0 https://community.jboss.org/thread/195459?tstart=0 https://community.jboss.org/message/625902#625902?tstart=0 https://community.jboss.org/message/625902?tstart=0 Thanks. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/750513#750513] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

Could you please comment on following: - what peristence.xml settings to you use - especially important hbm.ddl.auto - have you tried to clean up db and start fresh? - is there any other modification to the installed jbpm (using installer) then the CustomWorkItemsHandler.conf and putting handler on class path? Anything else you could think of for your environment.

[jBPM] - Any info / developments / plans for a generic Web Service (SOAP) Service Task / WorkItemHandler?

by geus

geus [https://community.jboss.org/people/geus] created the discussion "Any info / developments / plans for a generic Web Service (SOAP) Service Task / WorkItemHandler?" To view the discussion, visit: https://community.jboss.org/message/750402#750402 -------------------------------------------------------------- I'm a newbee to jBPM and please forgive me if this question is stupid ;) I've tried to find information about calling a Web Service (e.g. SOAP), by e.g. adding a specialised Service Task in the Drools-Guvnor editor or in the Eclipse editor. It would be really nice to somehow use an existing WSDL and integrate it within the process design (and subsequentlty execute it afterwards). Unfortunately, I have not found something which precisely covers this. In this discussion ( https://community.jboss.org/message/581911#581911 https://community.jboss.org/message/581911), the same question was asked but that was more than a year ago. Also, I've noticed there exist several custom WorkItemHandler implementations which can be assigned to a custom Service Task ( https://github.com/droolsjbpm/jbpm/tree/master/jbpm-workitems/src/main/ja... https://github.com/droolsjbpm/jbpm/tree/master/jbpm-workitems/src/main/ja...). However, I did not find some SOAP / WSDL aware implementations. Can anyone please point me to some more info or current developments on this? Or is there a roadmap for such a feature? Many thanks in advance!

I am able to assign a user to a task using the delegate() method in the TaskClient class but I see no way of delegating to a group. Has anyone implemented anything that will assign/delegate a task to a group? This is a requirement for the application I am working on so I'd appreciate some help in resolving this.
