Can not read file from URL

Question

I have this code for loadbitmap() function:
String s = getCodeBase()+sdir+sfile;
System.out.println("codeBase is=" + s);
URL url = new URL(s);
InputStream fs = url.openStream();
BufferedInputStream bs = new BufferedInputStream(fs);
And the file is a .bmp file, so I go on decoding this etc. It works fine within VisualCafe.
When I created a virtual directory in IIS and run this applet from
http://localhost/ImageApplet/ImageApplet.html address:
I get in 1.3.1 Plug-in this error:
codeBase is=http://localhost/ImageApplet/duke/some1.BMP
Caught exception in loadbitmap!java.io.FileNotFoundException: http://localhost/ImageApplet/duke/some1.BMP
If a type this as address in browser, it shows the image.
Could any one tell me what I am doing wrong here?

Answer 1

You can try this, even though it is not supposed to be different from your original code:
URL url = new URL(getCodeBase(), sdir+sfile);
System.out.println("getting image from " + url);
InputStream fs = url.openStream();
BufferedInputStream bs = new BufferedInputStream(fs);
I could understand a SecurityException but a FileNotFoundException... A FileNotFoundException... You are reading from a stream originating from a URL, not a file!!!
Which line causes the exception?
