Following generic method just tries to read some files that match a  
pattern . It uses the Find class which is throwing an error[1]

def loadFiles(dir)  
logger.debug “\>\> dir : #{dir}”  
messages = []

```
Find.find(dir) do |f|
  next unless File.file?(f)
  name = File.basename(p)
  messages << f if File.fnmatch('*.FileStreamStore', name)
  logger.debug ">> messages : #{messages.inspect}"
end
messages

```

You need to require ‘find’
