The following method is called:
public static String readTextFileFromUrl(String url) throws IOException {
try(InputStream is = FileSystemStorage.getInstance().openInputStream(url);)
{
InputStreamReader br = new InputStreamReader(is);
int numChars=is.available();
char[] b=new char[numChars];
br.read(b, 0,numChars);
br.close();
return new String(b);
} catch(IOException err) {
String error=err.getMessage();
System.out.println("write exc "+error);
}
return null;
}
