As of this writing, the SAJAX home site only provides 2 example uses of SAJAX. Unfortunately, only one of those demos seem to work.
Multiplier
Multiplier is one of the most basic examples of AJAX. This is a good starting point if you have never programmed AJAX sites before, and have very little experience with the language you are using SAJAX with.
Oldschool "Graffiti Wall"
Graffiti Wall shows how AJAX can use a timer to automatically pull changes from the sever. This is a little more advanced than the Multiplier, but is still a fairly basic use of AJAX.
These examples are included in the SAJAX download.

If you are trying to install the "Graffiti Wall" on your local webserver, you need to make sure that the path to the file the example writes to exists (and I think the file needs to already exists), and that your webserver has read/write permissions on the file.
These examples are included in the SAJAX download.
