writing multiple lines to a java file

I'm trying to create an error report in Java, but the file reader writes over the same line every time I find a new error, so all that displays is the last error. How would I prevent this?

public void errorReport(String error)
{
    try {

    FileWriter fw = new FileWriter(file);
    PrintWriter pw = new PrintWriter(fw);
        pw.write(error);
        pw.close();
    } catch (IOException e) 
    {
e.printStackTrace();
}

} // end error report

FileWriter fw = new FileWriter(file, true);

The second argument is "append mode." If it is true, then the FileWriter will append lines instead of writing over them.
