I am certain you can write to a file on the server from which the
applet started. I have not written to a file, but I have read from a
file on the same server. Here is the code for reading from a file. I
am sure it can be easily modified to write to file on the server. I
the example below, CarDriver is simply a class to hold data from the
file. I did not include it, because the file access code is what is
of interest here.
/**
* get data from the server on which the applet started
* for ParkingLot database and put into a Vector
* and Hash Table of car drivers
* @exception MalformedURLException
* @exception IOException
*/
public void readParkingLotData() {
try {
// Connect to the file at the url of this applet
URL dataFile = new URL(getDocumentBase(), FILE_NAME);
// Open an input stream to the datafile at the url
InputStreamReader inputStream = new
InputStreamReader(dataFile.openStream());
// Assign a buffered reader to the input stream
BufferedReader bufReader = new BufferedReader(inputStream);
while ( true ) {
String line = bufReader.readLine();
if ( line == null ) {
break;
} else {
CarDriver carDriver = getDriverAndCar(line);
// put into vector and hashtable
if ( carDriver != null ) {
carDriversVector.addElement(carDriver);
carDriversHash.put(carDriver.getCar().getLicensePlate(),
carDriver);
}
}
}
}
catch (MalformedURLException e) {
licensePlateField.setText("Error: Could not open the data file
'" +
FILE_NAME +
"' on the server.");
}
catch (IOException e) {
licensePlateField.setText("Error: Could not open the data file
'" +
FILE_NAME +
"' on the server.");
}
}
