Hey The problem is you are directly posting array of objects. So Struts2 don't know whicch method to call. Change your json data like below. Then it will work.

{"data":[{"id":"1","code":"111","name":"ffffd"},
"id":"2","code":"222","name":"sss"},
{"id":"3","code":"333","name":"eee"}]}

Then inside the setter read with object

public void setData(List < Report > data) {
    System.out.println("Setter Call Flow");
    this.data = data;
}

Where Report is a java class contains id,code,name as it's members with setters and getters.
