Subject Re: How to convert String to Date in EL?
Date Tue, 20 Aug 2019 08:44:01 GMT
Because formats for dates are so ambiguous, there's no reliable way to
interpret. The is why you'd use the parseDate tag, probably inside a set to
get a date object that you'd then pass to your dateparam thing. Presumably
you could write an el "function" to do that inline if you wanted to out in
the effort to clean your JSP further, as I don't know of such thing
existing (though I can't imagine why it shouldn't, save to discourage
everyone putting all their application logic and validation in JSPs)
