Is the applet trying to connect to a database on a server other than the one the applet comes from?

Yes. The link given there a web hosting. I have an account there.
But I wanted to connect to the database of my account supported by the hosting site.

"AccessControlException: access denied"

MySQL needs to be set up to accept connections from outside the server.
It's possible this hasn't been done with the one on your server.

I do not know how to do this, before you ask...:)

That's a problem...
My account doesn't accept external access to the database.
Should I use a firewall tunneling to bridge the external access issue?

How about this?
Could I use my .php functions to call a database connection on to my JApplet?
Or if not, could I use the functions of my .jsp to do the database connection to the JApplet and vise versa?
