Duplicate getters and setters

Question

Hi,
Can any one tell me why do we need getters and setters both in class and backing bean? Is not a duplication?
Here is an example
In my class Dept I have getDept_Code,getDept_Name and setDept_Code,set_DeptName.
and in my backing bean(DeptBean) I have same getters and setters.
please note that in my Dept.jsp I use these as follows
value="#{DeptBean.dept_code}".
value="#{DeptBean.dept_name}"
My question is why dont we use getters and setters in Dept class. and do we need to have getters and setters in backing bean?
plz explain.

Answer 1

You just can use the getters in Dept? You don't need to "flatten out the objects".
MyDto:public class MyDto {
   private String field1;
   private String field2;
   // + getters + setters
}MyBean:public class MyBean {
    private MyDto myDto;
    // + getter + setter
}JSF<h:outputText value="#{myBean.myDto.field1}" />
