Web Server Gateways

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, jConnect includes a Java servlet that you can install on any Web server that supports the javax.servlet interfaces. This servlet enables jConnect to support encryption using the Web server as the gateway.

• TDS tunnelling
  jConnect uses TDS to communicate with database servers. Requests from a client to a back-end server that go through the gateway contain TDS in the body of the request.
• Configure jConnect and Gateways
  There are several options for setting up your Web servers and Adaptive Servers to install the jConnect driver and to use a gateway with the TDS-tunnelling servlet.
• Usage Requirements
  Review the usage requirements for Web server gateways.
• TDS-Tunnelling Servlet
  To use the TDS-tunnelling servlet, you need a Web server that supports the javax.servlet interfaces, such as the Oracle Corporation Java Web server.
