This handy method can be used to validate user input or configuration, where single space or newline characters should also be treated as invalid. It will be available in version 3.0 of Lang library.
I know this contribution is so tiny and not very significant, probably not even worth to mention, but I am still proud of it ;-).
Meanwhile I past the middle of "Open-Source ESBs in Action", which is a great book comparing Mule and ServiceMix. Sadly, after first two examples I found Mule to be much more intuitive and easy to use, so I skip ServiceMix chapters. Maybe I will go back to them one day, but for now expect few Mule ESB related articles in the future, as this is the topic I would like to focus now. Tags: commons, esb, mule
