File Creation

Hi all
I am now doing a webapplication involving servlets.i want to creat
a dynamic view of an image.the image generated will be of type
BufferedImage and i want to write it into a file.i have created the
file using File class and CreateNewFile()method.but the file is not
created on that location.can anyone tell me why is this so? also tell
me whether wait() method will help to suspend a servlet for sometime?
Thanks in Advance

Anu
