Can you explain to us why you believe that the regex is for five letter words?

FWIW, I have a project called Toothpicks where I get my regex's working. It's nothing but the regex under development and a test harness. Much easier than getting it working in "live" code. Been doing it this way for 20 years, the toothpicks name comes from a Perl expression when dealing with the strings of \/\\\///x\/\\\/2\//\v type.

This afternoon I actually dropped down to perl so I could use it's regex debugger. Got it working quickly, but then couldn't port the silly thing to Java

Try "\\b\\w{5}\\b" for your expression. Using "\\s" just checks for whitespaces.
 
I agree. Here's the link: http://aspose.com/file-tools
