If you had the library, you could do this, but it'd be asking for trouble, because the class might change names at some future point (or maybe already has in CF7).
java.util.Hashtable implements java.util.Map, so therefore CF structs also implement the interface. Your original question was about passing a CF struct into Java. Since the CF struct implements the Map interface, you can declare your parameter of type Map, and treat the CF struct exactly as any other Map instance you might come across. If, however, what you need to do is create a CF structure in Java and return it to CF, you're in a bit of a bind. You can do it, but I wouldn't. Rather, I'd just return a Map (your choice of implementation) and then use it from your CF with the Map interface (i.e. contains(), put(), get(), etc.) rather than the native CF struct nomenclature. That'll give you more flexibility down the road, and since you're already programming in Java, continuing to use the Java methods shouldn't be a hassle. If nothing else, you can return the Map from your Java method and then convert it into a CF struct. As for your interface exception, you can't instantiate interfaces, you have to instantiate a class that implements the interface. java.util.Hashtable and java.util.HashMap are the most common choices (the former is synchronized, the latter isn't), and there's a java.util.TreeMap as well in the core JRE. cheers, barneyb On Tue, 8 Feb 2005 20:14:33 -0500, Troy Simpson <[EMAIL PROTECTED]> wrote: > Hey, > I want to add that I found this article at bpurcell.org: > http://www.bpurcell.org/blog/index.cfm?mode=entry&entry=925 > > It says that a ColdFusion Structure is an Object of type > coldfusion.runtime.Struct.
