Retrieving data from remote server in an applet.

I am new to java programming, and I want to make sure I am going in the right direction before spending time on this project.


I have to upload an applet onto a server that I have no control over.
  * No way to change this

That applet needs to connect to a remote server (which I do have control over) and retrieve data from a MSSQL Server database on it.

I was thinking about putting a servlet on the db server that connects to the database and then connecting to that servlet from the applet.

Am I going in the right direction, or is there a better way to do this?

Thanks,
Dan

What exactly do you mean here? You mean putting the applet class file onto a server that you do not have control over? Can you be more specific?

Yes, I have to put the class file on someone else's server.  The applet will be served up to a web browser from that server.  I cannot change anything on that server (settings, security, drivers, etc.).

Does this server have FTP? Do you want to do it programmatically?

I can put the file there with no problems (there is a web interface designed specifically for that purpose).  Maybe i should have left that part out of the original question.  My concern is how to get the data from the database server.

Open a database conenction from the applet to the server. You will need to sign the applet or chaneg the java.policy file if the db server and the web server are in different computers. For more info on database stuff have a look here: http://java.sun.com/docs/books/tutorial/jdbc/
