How To Validate HTML Tag Using Struts 2

I have one JSP page

I have action class Us

Solution 1:

You have to use some Struts2 tags. If you do not want to use <s:textfield> tag then use <s:fielderror> tag which renders field errors.

Solution 2:

The validation works fine on html tags, i.e. <form <input if the name attribute matches the fieldName specified in the validation.xml.

Solution 3:

No need to change conf anything. Just change all Struts <s:form> tags to html tag <form> and only add <s:fielderror> </s:fielderror> in your code. It is perfectly working.
