• Will be replaced with the ToC, excluding a header {:toc}

Description

The followings show a simple example using Webwork's Field Validators

Step 1

Create the jsp page.

<s:fielderror cssClass="alert alert-error"/>

<s:form method="POST" action="submitVisitorValidatorsExamples" namespace="/validation">
    <s:textfield name="user.name" label="User Name"/>
    <s:textfield name="user.age" label="User Age"/>
    <s:textfield name="user.birthday" label="Birthday"/>
    <s:submit label="Submit" cssClass="btn btn-primary"/>
</s:form>

Step 2

Create the action class.

public class VisitorValidatorsExampleAction extends AbstractValidationActionSupport {

	private User user;

	public User getUser() {
		return user;
	}

	public void setUser(User user) {
		this.user = user;
	}
}

Step 3

Create the validator.xml.

<validators>
	<field name="user">
		<field-validator type="visitor">
			<param name="context">userContext</param>
			<param name="appendPrefix">true</param>
			<message>User:</message>
		</field-validator>
	</field>
</validators>
