I've decided it's probably time to write a chatroom for my website (and to learn how these work). I know PHP (and ofcourse Java). My webhoster doesn't allow Servlets, else it'd be easy. I don't want to use META refresh tags to do it, that would be a pain the the ***. How would I do this? How would I organize the sockets?
Just some general ideas/tips would be helpful.

In the US, sockets are placed in junction boxes which are routinely attached to wall studs (2 X 4) with rectangular cutouts in the drywall where wall plates are used to cover the wires and plug.
Google is your friend.

You are going to use applets and HttpURLConnection to a web service written in PHP.
So...
User types in Applet -> Applet posts content to Web service -> You do something in PHP
Applet (every so often) -> applet sends request for latest content to web service -> You send back data as XML from PHP -> Applet reads XML and gets latest content and displays

Yes. But not every Servlet is a Java Servlet.
You need a servlet in the sense of "some code that runs on the web server" This could be a Java Servlet, ASP, PHP, Perl, ColdFusion, etc.

Okay please READ over my previous posts.
Your client side will consist of an applet.
The applet will use HttpURLConnection to connect to your web page (done in PHP).
Your PHP will output XML.
The applet will parse the XML and get the content.
The applet will display it.
No META tags, and I never mentioned them. And no direct sockets in PHP either, I never mentioned them either. So please don't mention them again, they aren't needed and you are worrying about things you don't have to worry about.
How would I organize what the people say? If I try to use a flat file I'll run into problems with it being used and stuff like that (syncronising the File wouldn't help between more than one applet), if I use a database I could easy beat it to death if the chatroom got busy.
humm...
Thinking aloud, applet sends data to another php page that appends the text and user (combined into an object) on to another object that holds the data. The XML page gets the data from that object. How could that object exist between the two...
Note: only heard of Ajax, never used it.
