Question

I got a simple form validation and submission that works great

Here is my struts.xml :

    <action name="register" class="registerAction">
        <interceptor-ref name="defaultWithoutAuthenticationStack"/>
        <result type="tiles" name="input">
            <param name="titleKey">global.title.register</param>
            <param name="location">register</param>
        </result>
        <result type="tiles" name="success">register.success</result>
    </action>

My jsp form :

<s:form method="post" action="register.action" validate="true">
    <s:textfield name="usernameRegister" id="usernameRegister" key="global.username" labelposition="left" />
    <s:password name="passwordRegister" id="passwordRegister" key="global.password" labelposition="left" />
    <s:password name="passwordConfirmRegister" id="passwordConfirmRegister" key="global.password.confirm" labelposition="left" />
    <s:textfield name="emailRegister" id="emailRegister" key="global.email" labelposition="left" />
    <s:submit key="global.register" name="submitRegister" method="goRegister"></s:submit>
</s:form>

And my submit function :

public String goRegister(){
    user.setUsername(getUsernameRegister());
    user.setPassword(getPasswordRegister());
    user.setEmail(getEmailRegister());
    userService.addUser(user);

    ArrayList<String> successMessageUsername = new ArrayList<String>();

    successMessageUsername.add(getUsernameRegister());
    this.addActionSuccess(getText("global.register.success", successMessageUsername));
    return SUCCESS;
}

Nothing fancy !

The problem is I got a windows asking for resubmit form informations when I refresh my page on success page or form page (when validation failed)

How can I prevent that ?

Thx

EDIT : I add the action messages and fields messages preservation to my question
How to preserve the actions messages and fields messages (validation) with a redirection ?

Answer 1

Use the post-redirect-get pattern.

On success, redirect to the “you’ve registered” page. That way if the user refreshes, they just get that same page again.
