Using the validate() method of the ActionForm class, the values filled in the form will be validated in the case there is no JavaScript for validating the form.

validator framework requires two xml files, namely

1.validator-rules.xml

2.validation.xml

validator-rules.xml

Files provides the rules for the ready made validation available in the framework.

ex:-

Required Field, Requrlare Expression, Email-id etc...

Validation.xml

</field>

<var>

<var-name>max length</var-name>

HiStruts provide both client side and server side validation.for client side use for server side the best approach is to use DynaValidatorForm, specify form name in validation.xml and form property and its type and donot forget to make validate="true" in struts-config.xml at appropriate action.Cheers!Pardeep Dureja

Hi please follow thes steps for server side validation. I believe client-side validation is working fine for you and so telling you changes based on that. Hope you have given approriate entries in validation.xml and struts-config.xml.

1. just remove onsubmit attribute from the below given line in your jsp.

<html:form action="/Test.do" onsubmit="return validateTestForm(this)">

So it will look like

<html:form action="/Test.do" >

2. Add this error tag line before your form tag.

<html:errors />

<html:form action="/Test.do" >

3. Now comment validate method in your
FormBean.java

/***

public ActionErrors validate(ActionMapping actionMapping, HttpServletRequest request)

{

return null;

}

***/

4. Now your Form class should extend org.apache.struts.validator.ValidatorForm intead of ActionForm....

public class TestForm extends org.apache.struts.validator.ValidatorForm...

Thats all. It will work fine. All the best.

Hi guys!

we can validate form feilds in 3 ways.

1) using validator framework

2) using validate() method of formbean class. for this we need to set validate="true" in <action-mapping> tag of struts config.xml

3) otherwise we can validate in action class.. but this is extra round trip.

So in my view, using validator framework or validate() method of formbean class is good way.
