Re: Validate() vs JavaScript where is the advantage?

Hi,
I'm wondering if I should use validate() method of ActionForm instead of JavaScript to validate the form.  I can see the advantage of validate() when you have an internationalized application, but otherwise why would I have an overhead of going back to the server when I can do the validation on the client side?  I'm a struts newbie so I might not see the advantage of validate yet, so can someone tell me why JavaScript would be an inferior choice ( when internationalization is not an issue ). 

Thanks

In short, you don't have control over your users' environment.  They 
could be running old browsers; they could have JavaScript disabled; they 
could be running a browser with non-standard JavaScript support; their 
browser could be buggy.  Malicious users could even manually assemble 
HTTP requests with invalid data.

By using server-side validation, you take control over all of the data 
coming into your web application.  If you leave validation to the 
browser, there is always the chance that bad data is going to sneak into 
your system and do something that you don't expect.
