[JBoss jBPM] - Re: How to best control access from multiple threads to a Pr

by jse

Ronald Thanks for your answers. Am I right in thinking that two threads can, at the same time: 1) load the same ProcessInstanceForUpdate 2) Signal to their different tokens 3) Close the context (and thus commit the changed process instance state back to the database) ...without causing any clashes or hibernate exceptions, i.e. the different tokens provide true seperation between the two threads. To your other point: anonymous wrote : Is there a mechanism towards P if the 200 to E cannot be send? If not, why not just do it async? The main reason for wanting to keep async to a minimum is that it is quite heavy weight, requiring additional database persistance etc View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4197670#4197670 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4197670

[JBoss jBPM] - BusinessCalendar for each process definition.

by mikel＠consol.pl

Hi. Is it possible to define more than one Business calendar ? I have for e.g 5 process definition and i want 5 different calendars(calendars with different data). I want to associate them with process definition. Actually its only one properties file -> jbpm.business.calendar.properties which is loaded in static method in constructor. So we have one calendar for all jBPM. Any clues ? I dont want to override hundred of classes.

[JBoss jBPM] - Re: nulpointer in slightly complicated process

by kukeltje

What I get from your picture: - You want 5 to only execute if 1 and 2 have finished - You want 3 and 4 to execute if 1 has finished, but 2 might not have What you do is use the join on the right as a milestone... A join is a kind of milestone, but a very specific one. Instead of a join create a 'dummy' state node that does nothing (e.g. call it 'wait for 1 to finish' or milestone or whatever). Create a small javaclass that on node-leave for node 1, signals this dummy node to continue to 5. That is the correct way of doing it. In jBPM 4 things might change and this pattern might be supported out of the box either with a more flexible join or with options to signal other nodes so you do not have to write some small reusable additional java classes. How to signal or do something else from java in one node, related to another node see http://planetjbpm.wordpress.com/2008/10/01/implementing-milestones-in-jbpm/ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4197627#4197627 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4197627

[JBoss jBPM] - Re: nulpointer in slightly complicated process

by jjrs

Hi Ronald, I am slightly confused about what when a processdefinition is illegal. anonymous wrote : not all legs of the fork arrive in the same corresponding join. From the functional and dependency point of view, not always be possible to add intermediate fork and joins without affecting the dependencies. Is it possible to define a dependency graph like this one using parallel processing ? http://www.freeimagehosting.net/uploads/519702236e.png Right with my current settings it's impossible for me to execute Node5. We have been able to get rid of the SOE exceptions (we will explain how in the other thread) however, with a graph like this, we are not able to execute Node 5. Is there any other mechanism we could use for having such a dependency ?
