I have compiles the BPMN20.xsd, BPMNDI.xsd, DI.xsd, DC.xsd, Semantics.xsd togather with xjc for generating classes for jaxb,I am able to use these classes to create most of the tags in xml, but I am not able to find how to assign form data or declare variables in user task.here is the code:
package trial;
import javax.xml.bind.*;
import jaxbRefClasses.*;
import java.io.*;
public class conv {
private ObjectFactory ofact;
private TDefinitions def;
private TProcess proc;
public conv(){
ofact = new ObjectFactory();
def = ofact.createTDefinitions();
proc = ofact.createTProcess();
}
public void makeDefinition(){
def.setId("initial");
def.setName("new def");
def.setTargetNamespace("http://activiti.org/bpmn20");
}
public void makeProcess(){
proc.setId("processes1");
proc.setName("my processes");
JAXBElement<TProcess> thepro = ofact.createProcess(proc);
def.getRootElement().add(thepro);
}
public TFlowElement makeStartEvent(String id, String name){
TStartEvent st = ofact.createTStartEvent();
st.setId(id);
st.setName(name);
JAXBElement<TStartEvent> start = ofact.createStartEvent(st);
proc.getFlowElement().add(start);
return st;
}
public TFlowElement makeTask(String id, String name, TDocumentation doc,String asignee){
TUserTask t = ofact.createTUserTask();
JAXBElement<TUserTask> usertask = ofact.createUserTask(t);
proc.getFlowElement().add(usertask);
t.setId(id);
t.setName(name);
t.getDocumentation().add(doc);
//TExtensionElements ext = ofact.createTExtensionElements();
if(asignee != ""){
TPotentialOwner owner = ofact.createTPotentialOwner();
TResourceAssignmentExpression rae = ofact.createTResourceAssignmentExpression();
TFormalExpression fe = ofact.createTFormalExpression();
fe.getContent().add(asignee);
rae.setExpression(ofact.createFormalExpression(fe));
owner.setResourceAssignmentExpression(rae);
t.getResourceRole().add(ofact.createPotentialOwner(owner));
}
return t;
}
public void makeSeqFlow(String id, TFlowElement tskfrm, TFlowElement tskto , String condition){
TSequenceFlow sflow = ofact.createTSequenceFlow();
JAXBElement<TSequenceFlow> seqflow = ofact.createSequenceFlow(sflow);
proc.getFlowElement().add(seqflow);
sflow.setId(id);
sflow.setSourceRef(tskfrm);
sflow.setTargetRef(tskto);
if(condition != ""){

fe.getContent().add("${accepted == " + condition + "}");
sflow.setConditionExpression(fe);
}
}
public TFlowElement makeExclusiveGateway(String id){
TExclusiveGateway eg = ofact.createTExclusiveGateway();
JAXBElement<TExclusiveGateway> gway = ofact.createExclusiveGateway(eg);
proc.getFlowElement().add(gway);
eg.setId(id);
return eg;
}
public TDocumentation makeDocumentation(String inp){
TDocumentation doc = ofact.createTDocumentation();
doc.getContent().add(inp);
return doc;
}
public TFlowElement makeEndEvent(String id, String name){
TEndEvent ed = ofact.createTEndEvent();
ed.setId(id);
ed.setName(name);
JAXBElement<TEndEvent> end = ofact.createEndEvent(ed);
proc.getFlowElement().add(end);
return ed;
}
public void marshal() throws IOException {
try {
JAXBElement<TDefinitions> mydef =
ofact.createDefinitions( def );
JAXBContext jc = JAXBContext.newInstance( "jaxbRefClasses" );
Marshaller m = jc.createMarshaller();
m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
m.marshal( mydef, System.out );
FileWriter writer = new FileWriter(new File("a.bpmn20.xml"));
m.marshal(mydef, writer);
writer.close();
}
catch( JAXBException jbe ){
System.out.println("fail");
}
}
public static void main(String[] args) throws IOException {
conv k = new conv();
k.makeDefinition();
k.makeProcess();
TFlowElement tsk = k.makeTask("task1", "initiate",k.makeDocumentation("this is first documentation"), "user(fozzie)");
TFlowElement endtask = k.makeEndEvent("end", "the end");
TFlowElement gate;
// k.makeSeqFlow("start", "the start", k.makeStartEvent("start", "the start"), tsk);
k.makeSeqFlow("startflow", k.makeStartEvent("start", "the start"), gate = k.makeExclusiveGateway("first"), "");
//while tasks exist, loop

}
The output is:
