- 5. In the transform code I created the Object type in the header “ %type user = :object { class: "testweave.User"} ” And the payload of the transform is converted to User Object using the transform logic as below. { firstName: payload.user.name, lastName: payload.user.lastName } as :user

User.java package testweave; public class User { private String firstName; private String lastName; public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; } @Override public String toString() { // TODO Auto-generated method stub return this.firstName+" "+this.lastName; } }
