Hi,

there is no Shark API for creating XPDLs programmatically.
However, you can directly use JaWE's XPDL model implementation (which is 
also used in shark to parse XPDLs) to create XPDLs.
The following code creates XPDL Package, sets some properties, adds one 
participant, one process and one activity for the process.

       org.enhydra.shark.xpdl.elements.Package pkg=new 
org.enhydra.shark.xpdl.elements.Package();
       pkg.setId("test");
       pkg.setName("XPDL Test");
       pkg.getScript().setType("text/javascript");
       pkg.getPackageHeader().setXPDLVersion("1.0");
       pkg.getPackageHeader().setVendor("Together");
       pkg.getPackageHeader().setCreated("2006-12-13");
      
       Participant 
p=(Participant)pkg.getParticipants().generateNewElement();
       p.setId("secretary");
       p.getParticipantType().setTypeROLE();
       pkg.getParticipants().add(p);
      
       WorkflowProcess 
wp=(WorkflowProcess)pkg.getWorkflowProcesses().generateNewElement();
       pkg.getWorkflowProcesses().add(wp);
       wp.setAccessLevelPUBLIC();
       wp.setId("test");
       wp.setName("Test 1");
      
       ProcessHeader ph=wp.getProcessHeader();
       ph.setDescription("Description of process 1");
       ph.set("Priority","1");
      
       Activities acts=wp.getActivities();
       Activity act=(Activity)acts.generateNewElement();
       act.setId("actId");
       act.setName("Do something");
       act.getActivityTypes().setImplementation();
       
act.getActivityTypes().getImplementation().getImplementationTypes().setNo();
       act.setPerformer("secretary");
       act.setDescription("Test activity");
       acts.add(act);
      

To save such XPDL to a file you can do something like:

       Document document = null;
       DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
       DocumentBuilder dbuilder = dbf.newDocumentBuilder();
       document = dbuilder.newDocument();
       FileOutputStream os=new FileOutputStream("c:/test.xpdl");

       XPDLRepositoryHandler xpdlRH=new XPDLRepositoryHandler();
       xpdlRH.toXML(document,*pkg*);

       // Use a Transformer for output
       TransformerFactory tFactory = TransformerFactory.newInstance();
       Transformer transformer = tFactory.newTransformer();
       transformer.setOutputProperty("indent","yes");
       
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount","4");
       transformer.setOutputProperty("encoding","UTF8");
       DOMSource source = new DOMSource(document);
       StreamResult result = new StreamResult(os);
       transformer.transform(source,result);
       os.close();


Greetings,
Sasa.
