Geoff makes a couple blanket statements in his post about how the Java world doesn’t understand CFMX. I don’t agree with a couple of them:
· ColdFusion remains the only answer to making Java accessible to a mass of non comp-sci web developers — I don’t have a computer science degree, neither do 3 [...]
The second of my articles in ColdFusion Developer’s Journal is available on the website now: Extending ColdFusion with Java: Writing a Java-based CFX Tag. It’s a follow up on the last article I wrote; this one explains how you can write a Java CFX tag, the example again uses Lucene.
At work one of our developers is programming an ecommerce store against a Java API written by a third party. Said Java API returns a TreeMap object from a method and when you try to access that TreeMap object in any fashion, you’ll get an error, specifically:
“Error casting an object of type java.lang.Integer to an [...]
Doug posted a query on the cfguru list asking how he might retrieve whois information using ColdFusion. I mentioned that there are numerous tags (search on google if you want to see them), but that it’s pretty easy to do within ColdFusion if you drop the Jakarta Commons/Net jar into your ColdFusion lib [...]
Just got back from a trip to California & Oregon for a family wedding to find that the article I wrote for ColdFusion Developer’s Journal went live… check it out when you have a chance!
I mentioned yesterday that Sam posted some great code that lets you upload files to ColdFusion without using CFFILE. His code can be shortened considerably with the use of the init() method:
<cfscript>
fileAsString = “”;
fileReader = createObject(”java”, “java.io.FileReader”);
fileReader.init(form.upFile);
bufferedReader = createObject(”java”, “java.io.BufferedReader”);
bufferedReader.init(fileReader);
try {
do {
fileAsString = bufferedReader.readLine();
processLine(fileAsString);
} while (true);
} catch (coldfusion.runtime.UndefinedVariableException e) {
[...]
Sam posted some CF code that gives you the ability to upload a file to a web server without using CFFILE (ie: he uses Java instead): Handling file uploads without CFFILE.
On a related note, Oreilly has an article (Using the Jakarta Commons) that (will) introduce(s) each component in the Jakarta Commons library. Probably [...]
I’ve read emails [1] [2] from a couple different people on the various email lists that CFMX can’t use sockets…. which is true in the sense that CFMX doesn’t have a <cfsocket> tag, but not true in the sense that you can’t easily use sockets in ColdFusion. I banged around this morning for a [...]
Informative article on developerWorks titled Together at last: Sharing session data between ColdFusion and J2EE components. After you read that article, read my notes on creating session listeners for CFMX. I show you how to capture CFMX sessionOnStart and sessionOnEnd events using servlet listeners.
I little birdie told me that sessionOnEnd and sessionOnStart [...]
I wrote an article for Macromedia Devnet which was just published today! Check it out here: Server-Side Flash Detection Using BrowserHawk. If you’ve never used BrowserHawk before, it’ll be a good introduction. However, if you’ve used it with ColdFusion, you should definitely read it, I was able to use BrowserHawk [...]
