ok so is this mean both is server side validation and client side validation is done with Javascript? Also between these two(.xml and execute() method) which one is better? Any pros and cons?

No. Client-side validation is done with JavaScript, because that's what runs inside browsers. Server-side validation is done in Java, whether or not it's driven by XML. Also between these two(.xml and execute() method) which one is better? Any pros and cons? execute() method? Do you mean the validate() method? Neither is better--they're different things. XML/declarative validation is more useful for simple validations: length, masks, etc. The validate() method is more useful for business-logic-oriented validation, like if a business has a flag set then we only allow US addresses or something along those lines. The two are combinable; use XML for easy stuff, validate() for hard stuff.

Well, the DTD files are identical, only the URLs are different so I don't expect the outcome to be any different And it turns out it's not.

If insert, update and read modes, are represented by 3 different
submits that trigger the actions,
make them 3 different action mappings, then put validate=false in the
read action mapping, and true in the rest.
action path=/readAction name=yourForm validate=false

RE: Validation in Struts DisptachAction
Hi Vaneet
I'm no expert on this to be sure; but I ran into a similiar issue. What I did
was provided the check for the Read only mode in the forms validate method; if
read only mode the validate method returned null; otherwise it invoked the
super.validate method which performs the normal validation checks on the form.
Hope this helps.

How can such things be accomplished using struts without writing specific client-side validation javascripts functions on the jsp page? Any help is greatly appreciated. You will want to read up on the Validator framework. When you use the Validator, you configure rules about your form in an XML file. Struts will use those rules to perform server-side validation, but, for many basic types of validation, Struts can also (optionally) emit the proper javascript for client-side validation. You can still write your own javascript, if you need to or want to, but for many validation tasks -- including the can contains numbers only scenario you mentioned -- Struts will do it for you. You can find a HOWTO guide on the Validator on the Struts site here: http://struts.apache.org/userGuide/dev_validator.html Also, I believe the Struts distribution ships with a validator example. -Greg - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

In the jsp page you will have to put one struts javascipt tag. This tag will actually get all the custom java script for that page and thus client side validation java script will b put in jsp file. sachin xoriant, mumbai -Original Message- From: Divya B Sridhar [mailto:[EMAIL PROTECTED] Sent: Wednesday, September 15, 2004 9:51 AM To: [EMAIL PROTECTED] Subject: Validation in struts Hi All, It is said that the validation(client side validations like say a particular textbox field can contain numbers only etc) should not be explicitly written in client-side validation javascripts in a struts framework.

RE: Validation in struts
Hi Jitendar, Thanks for your help. I am using the validator framework now and I see that when I click the submit button, it does the validation and comes back with the error message on top of the page but does not pop-up a messagebox. I would want to prompt for a message box if, say a particular mandatory field is missed. - Now, I am using html:javascript also after the title tag. - edited validation.xml to have the field names. - included the validator plugin in my struts-config.xml - included errors.required in my application properties file. - included onsubmit function in my html:form to point to validatemyform(this) Is there something else that I am missing ? Thanks, Divya. -Original Message- From: Jitender K Chukkavenkata [mailto:[EMAIL PROTECTED] Sent: Wednesday, September 15, 2004 9:51 AM To: Struts Users Mailing List Subject: Re: Validation in struts U can use struts validations framework as well go thru struts validation framework..

RE: Validation in struts
Hi Divya, I think you need to extend your form class with org.apache.struts.validator.action.ValidatorForm or ValidatorActionFrom instead of org.apache.struts.action.ActionForm. have u done it? Regards, Jitender.
RE: Validation in struts
Hi Jitender, I guess it is import org.apache.struts.validator.ValidatorForm I have extended this as well. What should be done to show an error message box instead of showing it on top of the page ? I am sure I am missing something :) Thanks, Divya. -Original Message- From: Jitender K Chukkavenkata [mailto:[EMAIL PROTECTED] Sent: Wednesday, September 15, 2004 6:40 PM To: Struts Users Mailing List Subject: RE: Validation in struts Hi Divya, I think you need to extend your form class with org.apache.struts.validator.action.ValidatorForm or ValidatorActionFrom instead of org.apache.struts.action.ActionForm. have u done it?

RE: Validation in struts
Divya, if your problem is just to display an error message box instead of the message. use the javascript tag inside validator-rules.xml for your validation and map it with appropriate message key that you want to display. :) Jitender Kumar C.V.
Re: Validation in struts
It is said that the validation(client side validations like say a particular textbox field can contain numbers only etc) should not be explicitly written in client-side validation javascripts in a struts framework. How can such things be accomplished using struts without writing specific client-side validation javascripts functions on the jsp page? Any help is greatly appreciated. You will want to read up on the Validator framework. When you use the Validator, you configure rules about your form in an XML file. Struts will use those rules to perform server-side validation, but, for many basic types of validation, Struts can also (optionally) emit the proper javascript for client-side validation. You can still write your own javascript, if you need to or want to, but for many validation tasks -- including the can contains numbers only scenario you mentioned -- Struts will do it for you. You can find a HOWTO guide on the Validator on the Struts site here: http://struts.apache.org/userGuide/dev_validator.html Also, I believe the Struts distribution ships with a validator example. -Greg - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
