Stream Closed when accessing a jar file
I am writing an applet that reads text files from a folder in a jar file in order to get the information it needs. My current code for getting the contents of the jar file is:
publicvoid getStuff(String folder){
for(int i=0; i<stuff.length; i++){
ArrayList><ArrayList> holder=new ArrayList<ArrayList>();
try{
int num=i+1;
URL url =new URL("jar:http://www.geocities.com/bbubenheim/Grapher.jar!/"+folder+"/"+num+".txt");
JarURLConnection jarConnection = (JarURLConnection)url.openConnection();
BufferedReader in=new BufferedReader(new InputStreamReader(jarConnection.getInputStream()));
System.out.println(in);
String str="";
while ((str = in.readLine()) !=null){
ArrayList<String> line=new ArrayList<String>();
while(str.contains(",")){
String temp="";
temp=str.substring(0, str.indexOf(","));
// System.out.println(temp);
str=str.substring(str.indexOf(",")+1);
line.add(temp);
}
if(!str.contains(",")){
String tmep="";
tmep=str;
line.add(tmep);
}
holder.add(line);
}
stuff[i]=holder;
in.close();
}catch (IOException e){
System.out.println(e);
e.printStackTrace();
}
}
}
it works in NetBeans ("tmep" is the actual variable name, "temp" got boring), but when i try to put it in an html file, whose code is:
<applet code=Graph.class archive="InteractiveGrapher.jar" height=600 width=1000>
</applet>
(InteractiveGrapher is the jar with all the class files)., I get this error, which happens at the "BufferedReader in= new BufferedReader(new InputStreamReader(jarConnection.getInputStream()));" line:
java.io.IOException: Stream closed.

Is this geocities locking me out? It works from NetBeans so i thought the permissions or whatever it needs to access the jar file would be the same from a browser, any ideas?
