Thanks David. I've just got it working actually, I missed out a bracket
in my original solution, so the syntax should be
@FieldExpressionValidator(expression="(accountFileFileName.endsWith('.cs
v'))", message="", key="validate.invalidFilename",
fieldName="accountFileFileName")
Silly mistake I know. If I run into any more problems with it though
I'll use your suggestion - thanks

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
