Struts 2 <s:password> example

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 €œs:password€ with a key attribute or label and name attribute.

 

<s:password key="password" />
//or
<s:textfield label="Password" name="password" />

 
** UPDATE: Struts 2 Complete tutorial now available here.
 

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

Struts 2 <s:password> example

 
A page with “€˜password”€™ and “€˜confirm password”€™ fields, and do the validation to make sure the “€˜confirm password”€™ is match with the “€˜password”€™.

import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport {

	private static final long serialVersionUID = 1L;
	private String userName;
	private String password;

	public String getUserName() {
		return userName;
	}

	public void setUserName(String userName) {
		this.userName = userName;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public String execute() {

		return SUCCESS;
	}

	public void validate() {
		if (userName.equals("")) {
