Creating an HTTP Tunneling Client
Now that you understand Java serialization, let's put together an example using HTTP tunnel-
ing. The first part of this example is the client. This will be a simple application that opens an
HTTP connection to your servlet. It will then write the same
StudentList
object used in the
previous example to the open connection and wait for a response. The response will be the
original
StudentList
object echoed back to the client. The client can be found in Listing 6.3.
