I need an alternate method of CFTHROW...the environment that I am in does not allow this tag.  How do I get the same result without using CFTHROW.
<cffunction name="fullDuration" returntype="struct">
   <cfargument name="startDate" type="date">
   <cfargument name="endDate" type="date">
   <cfif dateCompare(arguments.startDate, arguments.endDate) gt 0>
        <cfthrow message="StartDate cannot be greater than EndDate">
    </cfif>
</cffunction>

if you are using it to only display messages out to the screen, you can make a custom tag to handle that and make it look pretty as well. if you dont care about how it looks you can just use cfabort to get the same ugly blue box and display the message you want

<cffunction name="fullDuration" returntype="struct">
   <cfargument name="startDate" type="date">
   <cfargument name="endDate" type="date">
   <cfif dateCompare(arguments.startDate, arguments.endDate) gt 0>
        <cfabort showerror="StartDate cannot be greater than EndDate">
    </cfif>
</cffunction>

if you do make a custom tag, it would go something like this


<cfparam name="Attributes.Message" default="">

<cfswitch expression=#thisTag.ExecutionMode#>
  <cfcase value= 'start'>
    <!--- Start tag processing --->
  </cfcase>
  <cfcase value='end'>

    put fancy HTML & design here
   
   
     <cfoutput> #attributes.Message#</cfoutput>
   
    <cfabort>
 
  </cfcase>
 
</cfswitch>

It seems really strange to me that they would not support cfthrow... I am curious how you verified that?   Did you get an error and they say "we don't support this.." meaning you're on your own.. or do they really mean, you can't use that tag.   I say this because the host has to catch errors, they all do... so why can't you throw on?

Did you try this...
<cfscript>
    // if you want to throw a database error:
    throw('database');
</cfscript>
