Let's configure a basic validation workflow, step by step.

Step 1

Create the input form.{snippet:id=basicValidation|javadoc=false|lang=xml|url=struts2/apps/showcase/src/main/webapp/WEB-INF/validation/quiz-basic.jsp}

Step 2

Create the Action class.{snippet:id=quizAction|javadoc=false|lang=java|url=struts2/apps/showcase/src/main/java/org/apache/struts2/showcase/validation/QuizAction.java}

Step 3

Create the validators. The validation.xml format is either <ActionClassName>-validation.xml or <ActionClassName>-<ActionAliasName>-validation.xml.{snippet:id=quizValidators|javadoc=false|lang=xml|url=struts2/apps/showcase/src/main/resources/org/apache/struts2/showcase/validation/QuizAction-validation.xml}

Step 4

Make sure there is a result for "input" listed in the struts.xml for when the validation fails:

xml<action name="HelloWorld" class="tutorial.HelloWorld"> <result name="success">/tutorial/createconfirm.jsp</result> <result name="error">/tutorial/error.jsp</result> <result name="input">/tutorial/create.jsp</result> </action>

If you don't have this, you'll get a: "No result defined for action xxx.xxx.tutorial.HellowWorld and result input" error

    Need a Step 4:

    Make sure there is a result for "input" listed in the struts.xml for when the validation fails:

    <action name="HelloWorld" class="tutorial.HelloWorld">
    <result name="success">/tutorial/createconfirm.jsp</result>
    <result name="error">/tutorial/error.jsp</result>
    <result name="input">/tutorial/create.jsp</result>
    </action>

    If you don't have this, you'll get a: "No result defined for action xxx.xxx.tutorial.HellowWorld and result input" error
