Re: Connecting remotely - multi tier

Hi all,

I'm new to this mailing list, so apologies up front if I commit a faux pas.

In general, the database will reside on a different machine from the web
server, and will not allow access from any machines other than some
internal ones.

Also, the login to the system should not be the same as the login to the
database. The middle tier has a different login to handle that.

If you want to avoid allowing the user to connect directly to the middle
tier and use it in unexpected ways, one option would be to use serialized
object communication between an applet (as the front end) and a
servlet (as the middle tier). You can then put encryption and other features
into your objects to further restrict user access.

Hope that helps!
