Well, I found the old code, but man it's a mess. I've put it in my googlecode repository at: http://musingrandom.googlecode.com/svn/trunk/cfmx/randomjava/ You'll only want a few lines, really. >From filestuff.cfm: targetDir = "C:\build"; // NO TRAILING SLASH!! currentDirectory = expandPath("./"); currentDirectory = replace(currentDirectory,"\","/","all"); urls[1] = createObject("java","java.net.URL ").init("file:#currentdirectory#"); GetObject = createObject("java","coldfusion.bootstrap.BootstrapClassLoader ").SystemClassLoader.newInstance(urls).loadClass("DirFilter").newInstance(); dumpvar(GetObject.doFileFilterDirectoryListing(javacast("string",targetDir))); And from the java file: File dir = new File(dirName); File[] files = dir.listFiles(); // This filter only returns directories FileFilter fileFilter = new FileFilter() { public boolean accept(File file) { return file.isDirectory(); } }; files = dir.listFiles(fileFilter); for (int i=0; i<files.length; i++) { System.out.println("[D] : " + files[i]); } I just couldn't figure out how to create a filefilter without using java... that "public boolean accept(File file)" got me. And the java class just spits text out to System.out, which isn't going to do you much good if you don't know where CF is outputting it to (that dump will probably just list the methods). I haven't re-tested this code since I was messing with it, not sure if it even still works... Sorry it's such a mess, I was really just playing around and never got it to the "share worthy" level. Hopefully it will give you an idea of how I did it though, maybe enough to do some testing...
