How do I have my Servlet return a binary file to the client?

There are a couple possibilities. One way (if the binary file is in the subtree of your docroot) is to do a redirection inside your servlet to the binary file as shown in following example:

GetFileThroughServlet1.java:

A second, more flexible way, is to return a file as a binary stream. The file doesn't need to be in the subtree of a docroot, for example you can get it off the network or from a database.
