Create a directory on the server based on the username logged in the client

Question

hello everybody,
All my files which are transferred from client to server are stored in a directory called "workspace".Before the user sends the files, he is authenticated.How can I create a directory on the user name who is logged in on the server???
Say, user1 has logged in and tries to send files to server.Now, I'd like to create a sub-directory user1 under work space so that all the files which he uploads will be stored under his name.When the user1 is logged in the first time, a directory will be created on his name else all files will be stored under his directory.
I'm using JDBC with my-sql.
ANy ideas??
Thanks for your time.

Well, it wouldn't matter what DB you are using....
You have the user name, correct?
You have the File object refering to the main directory, correct?
File userDir = new File(mainDir, username);
if(!userDir.exists()) {
   if(!userDir.mkdirs()) {
       throw new IOException("Can't make directory " + userDir.getAbsolutePath());
// use userDir to write any files...
