file loading
in [Java Help]
|
From: NickPick on 12 Apr 2010 21:47 The following code works well: ObjectFile f = new ObjectFile(); Scene loadedShip = null; try { loadedShip = f.load("C:/Users/Nicolas/Documents/ NetBeansProjects/3dGame/src/Gamestar/obj.obj"); However, if I chagne teh file path to "http://www....obj.obj" I get an error message: java.io.FileNotFoundException: http:\www.......obj.obj (The filename, directory name, or volume label syntax is incorrect) When I type in the file name, it works fine. Can't I use f.load if the file is on the internet? And why is it changing the http:// into http \. Could this be a problem? thanks

The three overloads of load() each require a specific parameter: Reader, String or URL. You might try import java.net.URL; .... URL url = new URL("http://www...obj"); loadedShip = f.load(url); .... <http://download.java.net/media/java3d/javadoc/1.5.0/com/sun/j3d/loaders/ objectfile/ObjectFile.html> -- John B.

For that matter, what is 'ObjectFile'? I guess you figure people reading this list are familiar with every Java class ever written? But given that you got a 'java.io.FileNotFoundException' I'll take a risk and guess that 'ObjectFile' is a class designed to work on file systems. Internet connections are not file systems, so yes, it will fail to grok an "http:" URL. Or so I surmise. As to why it changes the slashes, again based on the total lack of information you give about 'ObjectFile', I venture to guess that under the hood it's attempting to normalize file paths for your host platform. I'd say it's not so much a problem as a symptom of the effort to use a file I/O class for 'Net access. -- Lew
