Struts2 / css in textfield

Question

I am beginning with struts2 programming and I wondered how I could do the following thing. I have this struts code in a form :

<s:textfield name="aName"/>

And I had this html code before using struts2 :

<input id="aLogin" type="text" class="form-control" name="username" value="" placeholder="something" required autofocus>

How could I "merge" these two lines to do the same html code but using my struts2 code ?

Answer 1

In Struts tags, class ans style becomes cssClass and cssStyle; in old versions of Struts, required was an attribute indicating when to put the * mark, now changed to requiredLabel to avoid overriding the HTML5 required attribute. Other HTML5 attributes like placeholder and autofocus can be set because Textfield tag Allows Dynamic Attributes.

Then in your case:

<s:textfield id = "aLogin" 
           name = "aName" 
       cssClass = "form-control" 
          value = ""
    placeholder = "something" 
       required
      autofocus />

For other info, refer to the official <s:textfield/> documentation

Answer 2

name should be same as that of bean variable,therefore,

<s:textfield name="username"/>

this will work, only if you have setUsername method in your action class.
