Jolt Internet Relay
The Jolt Internet Relay is a component that routes messages from a Jolt client to a JSL or JSH. This eliminates
the need for the JSH and TUXEDO to run on the same machine as the Web server (generally considered as
insecure). The Jolt Relay (JRLY) is not a TUXEDO server or a TUXEDO client. It is a stand-alone program
that routes the Jolt messages from the Internet to the JSL or JSH
The Jolt Internet Relay consists of two components illustrated in Figure 3-1 .
Jolt Relay (JRLY). The JRLY is not a TUXEDO client or server. It is a stand-alone software
component. It requires only minimal configuration to allow it to work with Jolt clients. ●
Jolt Relay Adapter (JRAD). The JRAD is a TUXEDO application server, but does not include any
TUXEDO services. It requires command line arguments to allow it to work with the JSL and the
TUXEDO system.
Note
The Jolt relay is transparent to Jolt clients and Jolt servers. A Jolt server can simultaneously
connect clients directly to the Jolt Server (intranet clients), or via the Jolt Relay (Internet
clients).

Figure 3-1. Jolt Internet Relay Path
Figure 3-1 shows how a browser connects to the Web server software and downloads the Jolt applets. The Jolt
applet or client connects to the JRLY on the Web server machine. The JRLY forwards the Jolt messages across
the firewall to the JRAD. The JRAD selectively forwards messages to the JSL or appropriate JSH.
