Struts 2 Action Form bean

Hi I am new to Struts2. I have a requirement where i am mapping a Employee bean with Action and Employee bean further contains fields like firstname, last name and a further bean i.r address bean.I am not able to get the value of nested bean in action class.

Following is the brief code to explain the scenario


IN JSP :

I am getting the correct value for firstName and lastName in action class but if i try to access employeeBean.addressBean.address1 , i am getting null pointer exception.Can anyone tell me what changes i need to make to get the value.

I tried to print address1 value by employeeBean.getAddressBean().getAddress1() in Action class.

Are you getting the NPE when the page is displayed (as opposed to when the form is submitted?)

Not in jsp page .. but i tried to debug the value using debugger ,its showing the value of addressBean as null and when i tried to access the value in Action class using employeeBean.getAddressBean().getAddress1() i am getting NPE However i am getting the value of other fields of EmployeeBean.

Actually as per requirement i need to get this value in Action and perform some logic there.Is there any way i can map the value of nested bean fields with text box?

I assume this is when you are submitting this form. How are you displaying the form? Do you have a different action?

The code as you have it should work. Do you have a setAddressBean() method in employeeBean?

Sorry for replying so late .Setter methods were there. The problem occurred because i missed adding the default constructor in EmployeeBean.
After adding default constructor it worked .
