Are Oranges better than fruit? ;-) My understanding was that struts (ValidatorPlugIn actually) provided a means (JavascriptValidatorTag) for generating javascript to do initial client side validation based on rules you specify in an xml file. These rules may also be used on the server side (I think it was by extending ValidatorForm instead of ActionForm) so you get the best of both worlds. Haven't made use of these features myself so I dont know the details.
You will find yourself needing to do quite a bit of validation at the server side anyway (for example, the more complex validation based on your business rules where you need access to server side information to do the validation). It is also considered good practice not to rely solely on client side validation, for example , because clients might turn off javascript (since this will probably break all but the simplest form designs anyway, I dont actually regard this as a real reason - depends on which users you are targeting though. An intranet app can be more specific about its browser requirements than a mass market shopping portal website...). More sinister reasons are that if you dont validate things at the server end then you expose yourself to any garbage a malicious client might submit. They aren't forced to only submit to that url from the form you provide them. Again this would probably (but not necesarily) be of more concern to a public website than a restricted web app. Of course having validation done in javascript will give your users much quicker feedback, and thus improve their experience significantly, but its best to make sure that any input that can break your app if unvalidated is also checked at the server end too. One of the good things about struts is that it doesn't force you to use only the features it provides. If you are more comfortable using your own validation methodology then you can. -----Original Message----- From: Manish_Purang [mailto:[EMAIL PROTECTED]] Sent: Monday, July 01, 2002 15:03 To: [EMAIL PROTECTED] Subject: Struts vs Jsp/javascript.. Hi, Wanted to know whether or not Struts Framework scores over the jsp- javascript combination in terms of validation of form elements. I hope you are able to unedrstand what i am asking...? to make it clearer.. on one hand we have the jsp - javascript combination where in we can call a single javascript funtion to validate the form elements and provide for basic validations like NOT NULL , ONLY NUMERICALS... and so on... on the other hand we could use Struts ' validate function and do the same job... Which appraoch is better and any advantages of using Struts for the same...!
