hi,
struts validator provides both client side as well as server side validations.
if u want to use the serverside validations , u have to extend the validatorForm instead of ActionForm and remove the validate() method all together.
but, in my application, i am using validator for client side validations and on the server side i still use plain vanilla Action forms and validation method (for validations) for my own business requirements.
so its a matter of choice.

What should be in validate() method when we use Struts Validator package?
Should it be an empty method?

My current validate() method (without using Struts Validator) is as follows:(What should it be if I implement validations in validator-rules.xml and validations.xml)? Pl. suggest.

public ActionErrors validate(ActionMapping mapping,
javax.servlet.http.HttpServletRequest request) {
// maintenance forms do new, update and delete, but also searches and create new for
// fkey resolvers. Only new and update actually need validation.
if (!lrAction_.equals("New") && !lrAction_.equals("Update")) return null;

ActionErrors errs = new ActionErrors();
SupportValues support = new SupportValues();



try {
support.setContactName(contactName_);
} catch (IllegalArgumentException ex) {
errs.add(FLD_CONTACT_NAME,new ActionError("supportviewform.error_contact_name",ex.getMessage()));
}
try {
support.setContactDetail(contactDetail_);
} catch (IllegalArgumentException ex) {
errs.add(FLD_CONTACT_DETAIL,new ActionError("supportviewform.error_contact_detail",ex.getMessage()));
}
try {
support.setPhoneNo(phoneNo_);
} catch (IllegalArgumentException ex) {
errs.add(FLD_PHONE_NO,new ActionError("supportviewform.error_phone_no",ex.getMessage()));
}
try {
support.setEmailAddr(emailAddr_);
} catch (IllegalArgumentException ex) {
errs.add(FLD_EMAIL_ADDR,new ActionError("supportviewform.error_email_addr",ex.getMessage()));
}
try {
support.setSubject(subject_);
} catch (IllegalArgumentException ex) {
errs.add(FLD_SUBJECT,new ActionError("supportviewform.error_subject",ex.getMessage()));
}
try {
support.setMessage(message_);
} catch (IllegalArgumentException ex) {
errs.add(FLD_MESSAGE,new ActionError("supportviewform.error_message",ex.getMessage()));
} 
if (errs.empty()) return null;

// preserve selected values in the form, so on error don't lose them all.
preserveSelectedValues(request);

return errs;
} // end of validate
