Given examples of struts 2 will show how to validate a text area that must not be null and take values between 1 to 250 characters.
Here we have created five different files including three .jsp, one .java and one.xml files.
Please create all the required files and past the given code, once you done run your application and it will validate your text area, which will not take the value more then 250 characters and cant left blank.
Index.jsp
<ul><li><a href="roseindia/characterLimit.action">Characters and limiting Example</a></li></ul>
- - - - - - - - - - - - - - - - - - - - - - - -
Struts.xml
<action name="characterLimit"> <result>/pages/chatQuestion/limitedCharacter.jsp</result> </action> <action name="characterLimit1" class="net.roseindia.limitedCharacterAction"> <result name="error">/pages/chatQuestion/limitedCharacter.jsp</result> <result name="success">/pages/chatQuestion/limitedCharacterSuccess.jsp</result> </action>
