Issue

• How to bind form data to a java object in jBPM?

• I have performed below steps:

  • Create new business process
  • Import external jar with model object into BPM Artifact Repository (custom.Person contains methods: get/setName, get/setAge)
  • Add third party model jar as dependency to Business Process Project
  • Add Process Variable person of type custom.Person
  • Modify default start form to take input of Name and Age
  • Bind Form DataInputSet to person
  • Bind Form DataOutputSet to person
  • Update Form data origin to use id p (Input Id p_in Output id p_out)
  • Update Data Assignments on start form
  • AssignmentType: DataInput person is mapped to p_in
  • AssignmentType: DataOutput person is mapped to p_out
  • Create script task to execute java code

    System.out.println("Person: " + person); 

• Resulting output

   Person:  null
