If your database server runs on a different host than your Web server, or if you are developing Internet applications that must connect to a secure database server through a firewall, you need a gateway to act as a proxy, providing a path to the database server.
To connect to servers using the SSL protocol, SAP jConnect includes a Java servlet that you can install on any Web server that supports the javax.servlet interfaces. This servlet enables SAP jConnect to support encryption using the Web server as the gateway.
