Using methods with return values
Use CORBA methods that return values as you would any ColdFusion function; for example:
IDL double method(out double a);
CFML <cfset foo=3.1415>
<cfset ret=handle.method("foo")>
<cfoutput>#ret#</cfoutput>

ColdFusion supports specific CORBA data types and converts between CORBA types and ColdFusion data.
