This page contains an applet that uses Java IDL to connect to an EchoServer object running in a Jeeves servlet. The applet lets you make calls to the Echo Server object. You can specify an input string and see the resulting echoed string.
Note that this page assumes that the Jeeves web server is running on the localhost (and can be reached through the hostname "localhost") on port 8080. If this is not the case, please edit this html file.
