programatic creation of bpmn.xml

[newactivitiuser]

Hi,

I am very new to activiti and using 5.10 version. My project needs bpmn20.xml files to be created programmatically. My approach is to populate activity-bpmn model and then generate xml from it.
So when I use maven to generate classes from activiti-bpmn-extensions-5.10.xsd I am getting several errors as pasted below. I can modify the names of conflicting property using xjb but when i will generate xml back from models that would be a problem as it will not be adhering to xsd. Please help me.

I think you better (or at least also) ask this in a jaxb forum…

As of last month, there is a project that has the BPMN model and Activiti extensions built-in into a POJO-model that allows generating XML from it and the other way around (XML -> POJO).

See https://github.com/Activiti/Activiti/tree/master/modules/activiti-bpmn-converter, it's used in the designer and KIS modeler will probably be used in the engine itself when time allows it…

Great to see this initiative. This is going to open doors for projects looking for auto generation of the activiti bpmn from java model and the other way around ! Nice work frederikheremans. Iam hoping to use it soon for one of my project.
