Service Task with input/output xml create at java

Hello,

I want to create xml with input/output parameters.

I am using this code at java and how can I add input/output parameters before to create xml.

public String updateServiceTaskModel(ServiceTaskModelDto input) {
input.setXml(checkAndAddAttribute(input.getXml()));
ByteArrayInputStream byteArrayInputStream = null;
try {
byteArrayInputStream = new ByteArrayInputStream(input.getXml().getBytes(UTF8));
} catch (Exception e) {
throw new BusinessValidationException(“M001”, “can.not.get.xml.input.stream”, e.getMessage());
}

  BpmnModelInstance modelInstance = Bpmn.readModelFromStream(byteArrayInputStream);
  
  ServiceTask serviceTask = modelInstance.getModelElementById(input.getOldServiceTaskName());
 
  Collection<Process> processes = modelInstance.getDefinitions().getChildElementsByType(Process.class);
  Process process = processes.iterator().next();	
  			
  Definitions definitions = modelInstance.getDefinitions();
  
  BpmnDiagram diagram = modelInstance.getDefinitions().getBpmDiagrams().iterator().next();
  BpmnPlane plane = diagram.getBpmnPlane();
  
  ModelElementInstance modelElement = modelInstance.getModelElementById(input.getOldServiceTaskName());
  
  process.removeChildElement(modelElement);
  	    
  plane.setBpmnElement(process);
  diagram.setBpmnPlane(plane);
  definitions.addChildElement(diagram);

  
  
  ServiceTask task = createElement(modelInstance, 
  								 process, 
  								 input.getServiceTaskName().toLowerCase(), 
  								 GENERALSERVICEMODEL, 
  								 ServiceTask.class, 
  								 plane, 
  								 ThreadLocalRandom.current().nextDouble(MIN_POSITION, MAX_POSITION), 
      							 ThreadLocalRandom.current().nextDouble(MIN_POSITION, MAX_POSITION), 
      							 MODEL_BOUND_HEIGTH, 
      							 MODEL_BOUND_WIDTH,
  								 true);
  task.setName(input.getServiceTaskName());
  task.setImplementation(JAVACLASS);
  task.setCamundaClass(input.getServiceTaskClassQualifiedName());
  
  process.addChildElement(task);
  process.setExecutable(true);
  
  Bpmn.validateModel(modelInstance);
  return Bpmn.convertToString(modelInstance);

}

thank you.
