Hi
Because I dont read a naming convention. I think that the username hasn't got a blank.
I'm sorry for this error.
How do I change my username
Thanks

The Java Ranch has thousands of visitors every week, many with surprisingly similar names. To avoid confusion we have a naming convention, described at http://www.javaranch.com/name.jsp .
We require names to have at least two words, separated by a space, and strongly recommend that you use your full real name. Please log in again with a new name which meets the requirements.
Thanks.
