{code}
but only {code } File does not exist: /kiran {code} error message should be
thrown
{code} } catch (IOException ioe) {
System.err.println("FileSystem is inaccessible due to:\n"
+ StringUtils.stringifyException(ioe));
}{code}
i think it should use ioe.getmessage() method
{code}
} catch (IOException ioe) {
System.err.println("FileSystem is inaccessible due to:\n"
+ StringUtils.stringifyException(ioe.getmessage()));
}
{code}
