问题 When I create a new jBPM project in Eclipse and select Create as Maven Project the pom.xml is generated without the dependency section. While I can manually add the dependencies, shouldn't the plugin do this automatically? Am I missing something? 回答1: Are you using 6.4.0.Final? There were issues with that version of the Eclipse wizard, that should be fixed in the following update site: http://downloads.jboss.org/jbpm/release/6.4.1.Final/updatesite/ 来源： https://stackoverflow.com/questions

问题 I'm learning jBPM engine, and what I have noticed is that it uses MVEL dialect by default in process design. So the question is: what is the advantage of using MVEL instead of pure Java? Will I have troubles with more complex processes if I'll start to program them in Java? 来源： https://stackoverflow.com/questions/13516616/what-is-advantage-of-using-mvel

问题 I am stuck at strange issue. I have a jbpm5.3 web panel and what i am trying to do it to create web services in servlets by manipulating mysql database. i have done all the things but stuck in one byte array. this web panel uses a table workiteminfo in which it saves all the details and uses this byte array for further processing. My problem is that i do not have information about this byte array, but what i got to know is that this byte array is an object an unknown class. If i have this

问题 I have a business process requirement where a requestor should be able to "RECALL" the workflow-case he raised. The flow is like, Start ---> Requestor ----> Approver -----> Updater -----> End Requestor , Approver , Updater are human tasks. So after the Requestor task completed and goes to Approver task (and if it is not STARTED), the requestor should be able to "Recall" the process instance and flow should back to Requestor. I understand that a work-item for Approver "Human Task" will be

问题 We are trying to use Activiti in a new project. I've created a setup which uses Hibernate through JPA for persisting entities involved in the process and JPA is interconnected with Activiti so we can use these entities as JPA variables. See: JPA chapter of Activiti's documentation I've found out that Activiti doesn't allow me to create queries on processes which involves JPA variables where i like to filter on the JPA entity fields. For example if i have processes with a variable referencing

问题 In jBPM 6.2, we can assign an user task to either an actor or a group such that they are the potential owners of these tasks. Is there an user that we can define in code or bpmn file so that he can execute all the user tasks regardless of the fact that the task is assigned to him or not? 回答1: Create a user with the username "Administrator", or use one of your existing users and add it to the group "Administrators". This gives the user(s) in question access to the task as BusinessAdministrator

问题 I am evaluating JBPM 5.4 with a PoC and am trying to realize the benefits of persistence that the engine does when a StatefulKnowledgeSession is created with an appropriate EMF. i.e a use case example of, say, a case when a workflow, while in its execution flow encounters a jvm shutdown. How is resuming from point of failure handled? Are there examples which clearly show this resume behavior - which API's to use etc.. Also, are there other jbpm project examples to get used to the tool and
