How to deploy Modeler-generated BPMN to activiti

Hi everyone and I'm a newbie to activiti.I use activiti-modeler on tomcat to create a very simple BPMN.its bpmn20.xml is like:<?xml version="1.0" encoding="UTF-8"?><definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL" xmlns:bpmndi="http://www.omg.org/spec/BPMN/20100524/DI" xmlns:

OK, i managed to execute a test process. But when i enter the process instance page in probe, error continues.
Also when the model is imported, in BPMN file the humanperformer element has a resourceref property with no value.
This hinders activiti from successfully importing the BPMN. I have to delete the property manually. This is another problem.
The third is, After importing, the model's name in database is null, which requires also manual edit to show it on explorer page.
I wonder which property of the BPMN file implies process's name in database?

Hi,

Based on the BPMN 2.0 XML file you attached, I can see that the userTask doesn't contain any assignment logic.
So there is no assignee or candidate user and that's not right for a userTask. Also the implementation attribute says it's a webservice, but I think this is ignore by the Activiti Engine.
So if you model an executable process it should be no problem to deploy it on the Activiti Modeler.
Although you may look into the Activiti Designer, because that tool is even better suited to create executable processes.

Best regards,

Dear trademak

Thank you very much for reply.

Yes, you are right. I added assignment and the task can be seen at worklist.

But when importing to database, the name_ column is still null. This makes Processes in probe error.

LOL, you'll have to be a bit more specific with your question…
