Do you extend ActionSupport or just implement Action when trying to do
validation?
Have a look at the User registration example (in CVS only)
<snip>
public class UserRegistration
extends ActionSupport
implements ServletRequestAware,
SessionAware,
CommandDriven {
HttpServletRequest req;
Map session;
.... fields, setters and getters .....
protected String doExecute() throws Exception {
........code.....
if (ui != null && username.equals(ui.username)) {
addError("username", "Sorry. This username is already taken.
Please try another");
db.close();
return ERROR;
} else {
db.set(new UserInfo(this));
}
db.close();
return SUCCESS;
}
protected void doValidation() {
if (!getHasErrors()) {
// check if passwords match
if (!password.equals(confirmedPassword)) {
addError("password", "Passwords does not match");
addError("confirmedPassword", "");
}
// check if the email is valid by checking the host name
if (!Validator.checkEmail(this.email, this.netcheck)) {
addError("email", "This email does not have a valid
hostname");
}
.....more code...
}
}
}
}
</snip>
I guess you can chain your actions by setting another action as the
'success' result.
