Hi Nicole,
This is an action class that does validation of two parameters:
public class SignonAction extends ActionSupport {
private String username;
private String password;
@Override
public String execute() throws Exception {
Map session = null;
boolean authenticated = false;
try {
authenticated = Utils.authenticate(username,password);
} catch(Exception e) {
// Swallow the exception
}
if (authenticated) {
session = ActionContext.getContext().getSession();
User user = new User();
user.setLogin(username);
user.setEmail("set your email");
session.put("loggedIn", user);
return SUCCESS;
} else {
return ERROR;
}
}
@RequiredStringValidator(message="", key = "username.required")
@StringLengthFieldValidator(message = "", key =
"username.invalidLength", minLength = "6" , maxLength = "15")
@RegexFieldValidator(message = "", key = "prompt.invalidCharacters",
expression = "^[a-zA-Z0-9]+$")
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
@RequiredStringValidator(message="", key="password.required")
@StringLengthFieldValidator(message = "", key =
"password.invalidLength", minLength = "6" , maxLength = "15")
@RegexFieldValidator(message = "", key = "prompt.invalidCharacters",
expression = "^[a-zA-Z0-9]+$")
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
It uses annotation to validate.
Hope this will help.
Regards.
Pierre
