Try adding this to your action
static final Pattern pattern = Pattern.compile("^.+\\.((csv)|(xls))$",
Pattern.CASE_INSENSITIVE);
In your validateUpload method have something like
Matcher matcher = pattern.matcher(fileName);
if (!matcher.matches()) {
addActionError("File type not allowed");
return;
}
Remove |(xls) if you dont want to allow xls files
