getResourceAsStream working in eclipse, but not when run as applet in browser
I have an applet that needs to load saved data from a local text file that is in the eclipse package with the .java files. For use in this questions its name is "saveData.txt".
When I run the applet through eclipse, everything works perfectly. However, once I jar it up (making sure the txt file and .classpath files are included) and put it onto a website, the applet fails to load. I am getting an error of Unknown source on my InputStreamReader. I have included my code for loading and saving below. The error comes on the creation of the InputStreamReader Line.
Any Ideas where I screwed up?
private ArrayList loadLocations() throws IOException{
ArrayList locations = new ArrayList();
InputStream is = getClass().getResourceAsStream("\saveData.txt");
;; BELOW LINE is where exception is thrown
InputStreamReader isr = new InputStreamReader(is);
mInputStream = new BufferedReader(isr);
String line = mInputStream.readLine();
while (line != null && !(line.equals(""))) {
locations.add(new Location(line));
line = mInputStream.readLine();
}
if (mInputStream != null)
mInputStream.close();
Collections.sort(locations);
return locations;
}
private void saveLocations() throws IOException {
try {
mOutputStream = new PrintWriter(new File(getClass().getResource("\\saveData.txt").toURI()));
}
catch (URISyntaxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
;
for (Location l : locations) {
mOutputStream.print(l.getRawListing()+ "\n");
}
if (mOutputStream != null)
mOutputStream.close();
}
Full Error details (when run in browser)
