[JBoss jBPM] - Re: jBPM 4.0 instance creation results in single task

by holla2040

shekhar, I agree, that's what I determined and now understand why from your example. Here's a couple more questions, if you don't mind Is the 'task creation when necessary' approach common with all BPM engines? Does jBPM 3.x have the same approach? Thanks for your time.

[JBoss jBPM] - Re: [JBPM4] How to maintain class files for different Proces

by sushantgupta402

But in JBPM3 even if there is a chnage in the class definition one need not version their classes. JBPM takes care of the class versioning itself. But it seems that facility is not there in the JBPM4 please refer <JBPM4 Home directory>/doc/userguide/html_single/index.html#deployingclasses. But once discussing with one of the guy somewhere I came to know there is a way to handle this without changing the class but I could not recollect it. So posted in the forum.

[JBoss jBPM] - Re: [JBPM4] How to maintain class files for different Proces

OK, I do not think we are on the same page, Why do you want to change the class name or package name in the first place? The reason I recommended as an option was if you had to change the behavior of a certain class that gets invoked as part of the jbpm process execution. Say you have an assignment handler com.foo.Assign. This is currently deployed in a process definition ABC with version 1. If you have to deploy version 2 of the process, with changes to the code to com.foo.Assign, not always can you go ahead and do that, because some executions might already exist out there that could potentially break if you change the code of that class. If that is the case you have to version your class accordingly, and use the newer version in the new process deployment. If you think that changing the code does not impact the process definition, then why change the name of the class?

by shekharv

The task is created when the execution reaches that stage in the processDefinition. eg: | <task assignee="alex" g="277,235,92,52" name="review1"> | <transition g="-73,-25" name="approved1" to="review2"/> | </task> | <task assignee="alex" g="277,235,92,52" name="review2"> | <transition g="-73,-25" name="approved2" to="audit"/> | </task> | 'review2' will not be created until 'review1' is completed. Consider this: | <task assignee="alex" g="277,235,92,52" name="review0"> | <transition g="-73,-25" name="approved1" to="review1"/> | <transition g="-73,-25" name="approved2" to="review2"/> | </task> | <task assignee="alex" g="277,235,92,52" name="review1"> | <transition g="-73,-25" name="approved" to="review2"/> | </task> | <task assignee="alex" g="277,235,92,52" name="review2"> | <transition g="-73,-25" name="approved2" to="audit"/> | </task> | You have two options in tasknode review1: unless you pick one of them while completing the task, the next task cannot be determined, so the next task will not be created up front.

In JBPM3 even if there is some change in the class what all you have to do is make relevant changes in the class and deploye the whole process. No need to change the package of the class or class name. But in JBPM 4 you have to change the class name of class package both of which will result in changes not related to the business process modification.

Which would mean, bundled within your own application? What do you mean by jbpm3 not caring for class packaging?
