Struts 2 <s:password> example
In Struts 2 , you can use the <s:password> to create a HTML password field. For example, you can declare the “s:password” with a key attribute or label and name attribute.
<s:password key="password" /> //or <s:textfield label="Password" name="password" />
In Struts 2, the “name” will map to the JavaBean property automatically. In this case, on form submit, the textbox value with “name=’password’” will call the corresponds Action’s setPassword(String xx) to set the value
