Strange problem w/ DataInputStream in applet

Question

I have an applet that uses DataInputStream to read a data located on the server. The applet works perfectly when I run it with AppletViewer. However, when I mount it on the server, it garbles the data from the data file. It does seem to be finding the datafile, but it is no longer reading it correctly. If anyone can tell me why this might be, I'd be very grateful--I'm stumped.
Here's the relevant code:
public void getChinese(int offset){//to read font file                       
System.out.println ("Beginning try in gbbutton...");
try{                                                                      
URL url=new URL(dat.url, "Csf/cclib.jgb");
DataInputStream in = new DataInputStream(url.openStream());
in.skip(offset*72);
for(int i=0; i<72; i++){                                                
byte2[i] = (in.read()+256)%256;//(byte1, 72*offset, 72);
if(i==71)System.out.println(""+byte2);
in.close();
}catch (Exception e){System.err.println("Attempted to read Csf/cclib.j24 
from gbbutton" );}
Again, I know that the data processing algorithm is correct, because it works in appletviewer. Any ideas??

Answer 1

Thanks for the suggestion. It turns out that the applet is accessing the correct data file (the URL is okay), but that it is reading the wrong data from it. It seems like the skip method is not always skipping the correct number of bytes, when that number is anything over 20. It says in the API that skip doesn't always skip the right number of bytes, which seems pretty stupid to me. Any way to make this work properly, other than just putting skip(1) in a for loop to get the right number of skips?
