Re: Validation in Struts 1
That's not combining client- and server-side validation, that's combining declarative and programmatic validation, unless you're talking about the JavaScript validation method.

Re: Validation in Struts 1
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.

However, server side validation is also needed because clients can walk around client side intentionally. Please correct me if I said something wrong.
