Hi, I'm having a hard time following the tutorial located here... http://exadel.com/tutorial/struts/5.2/guess/strutstutorial-validation.html . I can't seem to go to the StrutsStudio website. Is it included in exadel studio? By the way, whenever I make a client side validation based on the tutorial I get the following error message...
