Struts 2 <s:textfield> example

Struts 2 <s:textfield> example

 
In Struts 2 , you can use the <s:textfield> to create a HTML input textbox. For example, you can declare the €œs:textfield€ with a key attribute or label and name attribute.
 

<s:textfield key="userName" />
//or
<s:textfield label="Username" name="userName" />

 

In Struts 2, the “€œname” will map to the JavaBean property automatically. In this case, on form submit, the textbox value with €œname=”userName”™€ will call the corresponding Action’€™s setUsername(String xx) to set the value
