I hope this makes it more clear:

Here are my methods

public static void toFile(File file, Object contents) throws
IOException {
       FileOutputStream out = new FileOutputStream(file);

I assume you got the Exception in the line above.
(Unfortunately you missed to post the complete exception stack trace)


   public static void toFile(String filePath, Object contents) throws
IOException {
       File file = new File(filePath);
       toFile(file, contents);

I get this exception thrown:

file:\C:\Documents%20and%20Settings\me\stave.ico (The filename,
directory name, or volume label syntax is incorrect)

The exception says it all: You try to open a file in directory
which, of course, doesn't exist.
What you really want to do, is to open a file in directory
    C:\Documents and Settings\me
I.e. you have to use
    C:\Documents and Settings\me\stave.ico
as filePath in your code above.

Then perhaps this might be a better choice:

        while((len = != -1) {
            out.write(b, 0, len);

    download(new URL(path), file);

    public static void download(String path, Object contents) throws

What do you think?


I have no idea what to do. All I want to do is create an icon at
C:/Documents and Settings/me called "stave.ico" with the contents
spawned within ImageIcon icon.

Don't confuse URL strings like
with real Windows file paths like
    C:\Documents and Settings\me\stave.ico
