I've been loathed to answer this thread as it is hard to explain why you
can't really do what you want in CFMX. There is one way to do it in
CFMX, but it isn't pretty and quite tough to explain. It would really
behoove you to rethink what you are trying to do or simply do it in
Java. Nevertheless, let me explain what the problem is.
I assume you are using the keys method, which returns an Enumeration.
Since an Enumeration is just an interface, the object returned really is
a Hashtable$Enumerator, which is an inner class of Hashtable that
implements the Enumeration interface. Thus, you can't really instantiate
a Hashtable$Enumerator. One idea would be the following.
<cfscript>
enum = CreateObject("java", "java.util.Enumeration");
enum = yourHashtable.keys();
foo = enum.next();
</cfscript>
If the above even works, enum.next() will return an Object, so it won't
be of much use. You would need to find a way to cast the Object into its
real type. This is where it gets ugly. The following might work.
<cfscript>
enum = CreateObject("java", "java.util.Enumeration");
enum = yourHashtable.keys();
foo = enum.next();
class = foo.getClass();
bar = CreateObject("java", class.getName());
foo = bar;
</cfscript>
Again, this is all real ugly and not functional. If you could tell us
what you are trying to do, possible we could find another way.
