Action and Namespace
A correct action and namespace attributes must be provided to the <s:form> tag. For example, if the action named "quizClient" is defined in the "/validation" namespace, the form must be configured as:
| Code Block |
|---|
|
<s:form method="post" validate="true" action="quizClient" namespace="/validation">
<s:textfield label="Name" name="name"/>
<s:textfield label="Age" name="age"/>
<s:textfield label="Favorite color" name="answer"/>
<s:submit/>
</s:form>
|
While the following will "work" in the sense that the form will function correctly, client-side validation will not. That is because Struts must know the exact namespace and action (rather than a URL) to properly support validation.
| Code Block |
|---|
|
<s:form method="post" validate="true" action="/validation/quizClient.action">
<s:textfield label="Name" name="name"/>
<s:textfield label="Age" name="age"/>
<s:textfield label="Favorite color" name="answer"/>
<s:submit/>
</s:form>
