[jboss-user] [JBoss jBPM] - Re: How hard to create visual representation of the relation

I'd go for (3). The API you are looking for is org.jbpm.jpdl.xml.JpdlXmlWriter. The problem is, this class is deprecated because there is no real need for it. You might as well build a DOM tree instead of a process definition object.

Here is a first attempt at the algorithm for your program:

For each process definition p:
Look for a node n in the target document whose name matches the name of p
If n does not exist, create it
For each subprocess sp in p:

Look for a node sn in the target document whose name matches the name of sp
If sn does not exist, create it
Create a transition from n to sn
No need for recursion, because you are iterating over all process definitions. If you know the "root" processes beforehand, you can develop a version of this algorithm that probably performs better.

Hope this helps.
