Hi all, I am just trying to work out how far to go in the project I'm doing with certain aspects of struts and after reading the last couple of date format mails "validation", of which I currently use none [if you cant type the data in correctly, back away from the computer (l)user], has come up as one of those things to think about.
How far and how deep into the application should validation occur? Now I can understand validation of the user input client side, that is only polite. But what should be validated server side? If I were to use multiple xml sources to generate a page (I use xslt not jsp) should I validate the xml structure of each source prior to generating the page? If these files are very large (I would be looking at anything up to 4MB) this would be very time consuming. Should I validate the xslt page, as there is no point in calling it if it's just going to throw an error. The xml sources will possibly be generated by dynamically formed xqueries to a database returning xml. I know the xquery should be validated prior to sending to the db, but should the returned xml be validated before sending back up to the Action? I am just asking incase anyone has any thoughts on this. It's not a when to use it question, more of a when to stop using it. Any thoughts or ideas on this would be appreciated, Regards Simon Institut fuer Prozessdatenverarbeitung und Elektronik, Forschungszentrum Karlsruhe GmbH, Postfach 3640, D-76021 Karlsruhe, Germany.
