I'm trying to do some reflection in coldfusion, basically to dump the DNS cache
InetAddress is currently holding in the JRE at the moment. I found a site that
offers a Java language example and I'm trying to convert it to CF tags. I'm
having trouble with this line...
Class<InetAddress> klass = InetAddress.class;
I've tried...
<cfset klass = createObject("java", "java.net.InetAddress")>
<cfset klass = createObject("java", "java.net.InetAddress").class>
<cfset klass = createObject("java", "java.net.InetAddress").getClass()>
<cfset klass = createObject("java", "java.net.InetAddress").class.getClass()>
but they all return the same error...
"The system has attempted to use an undefined value, which usually indicates a
programming error, either in your code or some system code. Null Pointers are
another name for undefined values."
What works is...
<cfset class = createObject("java",
"java.net.InetAddress").getLocalHost.getClass()>
but the object it returns does not have a declaredField of "addressCache", it
only has "INADDRSZ" "serialVersionUID" and "loopback" (I think because I'm not
creating an instance of the base class for reflection, it's an instance of an
instance. Not sure.
<cfset class = createObject("java", "java.net.InetAddress")>
doesn't work either because it has no declaredFields at all.
Is there a way in CF7 to reproduce this line...
Class<InetAddress> klass = InetAddress.class;
using CF tags so that I can pull back the correct object for reflection
purposes? Yes, I realize I could compile the pure Java language example, put
it on the CF server, and call it from CF, but for several reasons that's a
pain, long story, so... I'm hoping to do it in CF tags if at all possible.
Thanks
