THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
Let's configure a basic validation workflow, step by step.
Step 1
Create the input form.
Wiki Markup |
---|
{snippet:id=basicValidation|javadoc=false|lang=xml|url=struts2/apps/showcase/src/main/webapp/validation/quiz-basic.jsp} |
Step 2
Create the Action class.
Wiki Markup |
---|
{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
.
Wiki Markup |
---|
{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:
Code Block | ||||
---|---|---|---|---|
| ||||
<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
