Its not because of struts, int can not contain null, so nearest possible
brother is 0 so they put 0.
Ok, if you still want to use int, then put getter setter as String and
parse the input and output to integer and string.
int age = -1;
public String getAge(){
if(age<0)
return null;
else
return ""+age;
}
public String setAge(String age){
if(age == null)
this.age = 0
else
this.age = Integer.parseInt(age);
}
I think this solves your change of data type solves,
By the way one lesson I learned from experience was never use int,
float, boolean etc instead use Integer Float and Boolean etc.

That works. Thanks. I'm migrating from Struts 1 & was hoping not have
to change the data type.

Subject: Struts2: display int in JSP
Hi,
In my action, I have several variables of type int. When the variable
is not initialized, it's displayed as 0 in the JSP. I would like
un-initialized variable of type int to be display as blank/empty. What
is the best way to accomplish this? Thanks.
Public class XXAction extends ActionSupport
{
private int age;
private String name = new String("xyz");
private String email;
//getters & setters
}
JSP page would display:
Name: xyz
Email:
Age: 0
