Hi, I want to validate the date format in my rule. I just want to check whether my date is in the given format(yyyy-mm-dd) in my rule in Guvnor. Is it possible to do such validation in Guvnor? I tried the same but got an exception stating that the date is not in the given format(dd-MMM-yyyy). Can someone suggest a solution as to how to validate the date in Guvnor?
