I'm just a newbie so be kind.
Using Struts Validator PlugIn.
I finally have my files lined up and and get my validateRequired() to return when it should but my validateDate() is not working. In fact when I view source I don't even see it in there, the rest are there??? Any ideas? This is the date piece from the validator-rules.xml, it should be pretty much "canned" as I pasted it from an O'Reilly example. I'm not sure if anything else would help, if so let me know. Thanks in advance.

sorry, BLAH_DATE is just so I could find it faster when viewing source. It shouldn't be detremental as it doesn't harm the validateRequired(). Thanks again.
 
Forget this weirdo. You guys wanna see something really neat? I just have to take off my shoe .... (hint: it's a tiny ad)
