Do the DB validation in:
controllers.submits.LoginAction (execute) method.
The error handling should be:
If DB validation fails, create Action Error or Message and then pass it
back to the JSP as a failure.
The Error tags should be able to display it. If you use <html:errors/> you
dont have to manage individual <html:error> tags.

Subject: validate question ...
Hi,
My web-application allows a user to authenticate to the website.
I check for login and password with the Validator Framework (correct
length,
correct carachters, ...)
Then display with <html:errors property="login"/> and <html:errors
property="password"/> in my jsp.
This work ok.
If he the fields are valid, I need to check in my DB if the user is really
subscribed.
1) Where should I do the DB validation ?
2) How do I return the errors to JSP, how do I display the errors in my
jsp
?
can I have something similar like : <html:errors property="dberror"/> or
something like that ?
what's best ?
I have for this a "DynaValidatorForm" and an Action "LoginAction" if
fields
are correct for the validator :
<form-beans>
<form-bean name="loginForm" type="
org.apache.struts.validator.DynaValidatorForm">
<form-property name="login" type="java.lang.String" />
<form-property name="password" type="java.lang.String" />
</form-bean>
[...]
<action
path="/Login"
type="controllers.submits.LoginAction"
name="loginForm"
input="/Error.do"
validate="true"
scope="request">
<forward name="index" path="/index.jsp"/>
<forward name="chat" path="/chat_form.jsp"/>
</action>
And my JSP :
login :
<br/>
<html:text property="login" size="10"/>
<!-- <span id="txtUsernameMsg">
Le login spécifié est invalide !
</span>-->
<html:errors property="login"/> <--- DISPLAY error if
login is empty
<!--
I WANT TO DISPLAY A MESSAGE HERE IF USER DOESNT EXIST IN
DATABASE, how ?
-->
<br/>
mot de passe :
<br/>
<html:password property="password" size="10"/>
<!-- <span id="txtPasswordMsg">
Le mot de passe spécifié est invalide !
</span>
-->
<html:errors property="password"/> <--- DISPLAY error
if
password is empty
<br/>
