Subject RE: What should be in validate() method when using struts validat or package
Date Thu, 10 Jul 2003 09:54:40 GMT
Thanks for that. I've gone thru the pdf and am trying to implement client-side validations.
 
I've done as explained in that chapter.
I've placed the relevant code in .jsp file and also this line in the end (before closing BODY
tag).
 
<validator:javascript formName="supportviewForm"/>
 
But this is causing a problem. The form isnot getting displayed completely. It's showing the
following error:
javax.servlet.ServletException: org/apache/struts/util/MessageResources
        at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageCon
textImpl.java:536)
 
When I remove <validator:javascript formName="supportviewForm"/> from .jsp page, the
form is getting displayed properly. What could be the reason?

HI again
this pdf gives u good start to the validator framework
http://www.manning.com/husted/chap12.pdf <http://www.manning.com/husted/chap12.pdf>

 
also u can deploy the struts-validator.war that comes with the struts release and go thro'
the jsps, validator.xml, validator-rules.xml

Can you please explain how to use validator for client side validations? Any sample code on
the web (links would be helpful).


Thanks
Sriram

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.

Subject: What should be in validate() method when using struts validator package

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
