I forwarded both of the on-List replies, as well as an off-List one that should probably stay off-List, to my colleague, who in turn asked the customer if ssh tunneling is what we're talking about here; I was just told that the customer thinks this is indeed the case.

This should also answer Rob's questions:

Wintouch is a client-server CRM application, using a proprietary server running on an IBM Midrange box. In its earliest form, it used a Smalltalk(!) client communicating via APPC/APPN; by the time it had become a viable product, it had evolved into a Java Swing client communicating via TCP/IP (but still, with everything above the socket itself very much a proprietary protocol). Some years ago, we added web-based forms/portal capability, which in recent years evolved into a full-blown Java client that runs as a Tomcat context, serving not only forms and portals, but also something very close to the full Java-client, with the latter supporting both browser-based and mobile-app-based interfaces, both communicating with the original proprietary server and (mainly for reporting tools) issuing JDBC requests as well.

Naturally, of course, the Tomcat context can run on the same box as the Wintouch server, or on anything else that can run Tomcat, and communicate directly with that box.

So far as I'm aware, we haven't been told where this other web site will be running.

This situation looks, to me at least, like a case where the ssh tunneling would be entirely between the external web server and the Tomcat context. Which tells me that the next thing to research is ssh tunneling in Tomcat.

Thanks, all, and any further insights would be appreciated.
