file loading

[NickPick]

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);
....

What does the documentation for 'ObjectFile' say?

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.

It looks likely to be part of the Java3d API.

As was mentioned elsewhere, there is an overload of "load" which takes a
URL object.

Thanks! That worked!

And I will bet dollars to doughnuts that if the OP had bothered to take the
measly five minutes to answer my question for himself, he'd've seen those
overloads himself.
