Oops!
Hit the send key by mistake there:
<cfscript>
try {
socket = createObject('java','java.net.Socket').init();
remoteAddress=socket.getRemoteSocketAddress();
if (not structKeyExists(variables,'remoteAddress')) {
remoteAddress = -1;
}
}
catch (Any e) {
writeoutput(e.message);
remoteAddress=-1;
}
writeoutput("#remoteAddress#");
</cfscript>If the java method can return a null you need to check if the variable exists after assigning it. If it doesn't exist you got a null back.

CF7 already has the ability to do most of this:

The only thing it doesn't support is returning a null instead of say a struct or a query.
i think javacast is a special case. you can test for the existence of "nullValue" ok but this sort of thing below bombs. nulledVar is like long gone as far as cf is concerned, even to the catch bits. that output throws an undefined error. or something funky about catch scope, etc.
<cfscript> try { nulledVar=someJavaObjectThatCanReturnNull(); } catch (Any e) { nulledVar="something"; } writeoutput("#nulledVar#"); </cfscript>
