How to create a BPMN model without using activiti tools only from java code ?

[ilyass_act]

I'm working on a workflow project with activiti and i want to create a BPMN model from java without using activiti tools. for example i have 2 tasks in a model after some operation i want to update that model and add other tasks so i need to generate that from code but i can't figure that out any help ?

Check if this is of any help: GitHub - frederikheremans/activiti-dynamic-process: Activiti dynamic process example 

This example is building a process model via Java code.

Is there any example doc for Add TaskListener to UserTask..?

This is my code and it has run time errors

SyntaxEditor Code Snippet

UserTask userTask = new UserTask(); ActivitiListener activitiListener = new ActivitiListener();  activitiListener.setEvent( TaskListener.EVENTNAME_COMPLETE ); activitiListener.setImplementation( ImplementationType.IMPLEMENTATION_TYPE_CLASS ); activitiListener.setImplementation( "<my_package>.TestTaskListener" );  userTask.getTaskListeners().add( activitiListener );

And Error
org.activiti.engine.ActivitiException: Errors while parsing:
[Validation set: 'activiti-executable-process' | Problem: 'activiti-usertask-listener-implementation-missing'] : Element 'class' or 'expression' is mandatory on executionListener - [Extra info : processDefinitionId = my-process | processDefinitionName = my dynamic process | | id = task1 | | activityName = First task | ] ( line: 6, column: 74)

Any one familiar with this, Please help
