Date comparison

I'm a java engineer and having to work with some coldfusion. I have a date var coming in on a query string from a jsp page to a cfm page formatted as MMM-dd-yyyy. I need to see if that date has passed or not. Whether that date is in the future. I do not have the current date available. I'll need to generate that as well.

Thx.

I believe I figured it out...

<cfset removalDate = "na">
<cfif ParameterExists(url.rmdt) AND url.rmdt IS NOT "">
<cfset rmdt = "#url.rmdt#">
<cfset today = "#Now()#">
<cfset todayDate = "#DateFormat(today, 'mmm-dd-yyyy')#">
<cfif DateDiff("d","rmdt","todayDate") GT 0>
<cfset removalDate = "now">
<cfelse>
<cfset removalDate = "later">
</cfif>
</cfif>

Any of you cf guys want to dbl check this.... plzzzzzz

I didn't run this to be sure it works but this was my sweep of the code in general.

Code:

<!--- parameterExists() was depricated in CF5. The len( trim() ) call returns true if url.rmdt is not an empty string. I added a check to confirm that rmdt is a date. --->
<cfif isDefined( 'url.rmdt ') 
  and len( trim( url.rmdt ) )
  and isDate( url.rmdt )>
  <!--- don't think you need to dateFormat() the now() call in order to use dateDiff() on it.  Also, if the diff is greater than 0 the boolean check is true, so you don't actually need to say 'GT 0' in the cfif block --->
  <cfif dateDiff( 'd', url.rmdt, now() )>
    <cfset removalDate = "now">
  <cfelse>
    <cfset removalDate = "later">
  </cfif>
</cfif>
