Is that the same way one should do it in Java as well?
I sort of look at some code and see null or object being returned, and guess
have that stuck in my head.
Thanks Barney / Sean.

Subject: Re: [CFCDev] CFC return types
Here's the skeleton of the function:
<cffunction name="getUser" returntype="userCFC">
...
<cfif doesUserExist>
<cfreturn theUser />
<cfelse>
<cfthrow type="UserNotFoundException" />
</cfif>
</cffunction>
And then calling it:
<cftry>
<cfset user = getUser() />
.. do stuff ..
<cfcatch type="UserNotFoundException">
.. deal with the invalid user ..
</cfcatch>
</cftry>
Just for references, with a "null" return value the function would
return some kind of null instead of throwing the exception, and the
calling code would look like this:
<cfset user = getUser() />
<cfif user is null>
.. deal with invalid user ..
<cfelse>
.. do stuff ..
</cfif>
cheers,
