Site structure: index.html, index.cgi as opening pages
Run Java CGI only in cgi-bin folders
Ideas for uses of java, taking into consideration:
* level of difficulty
* potentially interesting to as many students as possible
Marquee example from textbook
Moving Marquee from textbook
Even fancier Marquee
What's wrong with this picture?
All these java applets with their messages assume static content. Static content means YOU decide the content, and those who come to your site are put basically in the position of non-interactants. This is the television model, I believe. You provide "viewers" with buttons, much like a remote control, but their effects on the web are minimized.
How does one make interaction meaningful?
Why not let the visitor affect the site?
form text element -> httpd -> cgi script uses database
new page <- write applet tag <- cgi script logs input
The following example will allow visitors to determine
the "marquee" message that the next person will see.
First the msgTag.php script that adds messages to the running list, and then returns the html page complete with the <applet> tag.
Next, the marquee.java modified textbook example reads the "msg" parameter to determine what it will display.
Finally, try running the script.
<form name=thisform action="" method=get>
<input type=text name=mymsg size=70>
<input type=submit value="send message">
