Struts 2 Validation
Struts 2.0 relies on a validation framework provided by XWork input validation. Along with basic validation and client-side Javascript validation offered in Struts 1.x, Struts 2 offers Ajax based validation. The following example demonstrates how to use Struts 2 validation, both basic and ajax validations. For this, the sample page used is shown below.
<s:form action="RegisterUser">
<s:textfield name="userName" size="20" label="User Name" />
<s:textfield name="emailAddress" size="20" label="Email Address" />
<s:textfield name="dateOfBirth" size="20" label="Date Of Birth" />
<s:submit name="submit" value="submit" />
</s:form>
Action defination is shown below:
<action name="RegisterUser" method="registerUser" class="example.RegisterUser">
<result name="input">/example/Register.jsp</result>
<s:form action="RegisterUser">
<s:textfield name="userName" size="20" label="User Name" />
<s:textfield name="emailAddress" size="20" label="Email Address" />
<s:textfield name="dateOfBirth" size="20" label="Date Of Birth" />
<s:submit name="submit" value="submit" />
