This example of JDA wiring uses three infotrons, one is a Button, which has no input, and one output terminal. It takes two properties in the html element which defines it, which gives the button caption, and the text to send to the next wired infotron when pressed. The next Infotron is a simple Ajax proxy which uses a generic cross-domain proxy hosted at mashup station. It only has one input terminal for specifying the url of the target service, and one output terminal for giving the results. The third infotron is a very simple presenter, which only has one input terminal and no output and which just creates a textarea on the node where it is defined and displays the input there.
