Maybe. It sounds like you probably are. There are two main areas of concern.
First, you need to protect access to instance variables; since you claim all
your variables are local to the doGet method you should be okay there. The other
area of concern is global resources such as files, connections, etc. The idea
here is that you may have a local variable that refers to a File object, but if
the File object is the same for all threads, you need to protect access to the
File if one thread could be writing while another is reading. It's hard to see
if you're okay in that area.
