I doubt Java per se has anything to do with the problem. Any web site which uses servletS or *.jsp is running a Java based application server or plugin. I use such sites all the time with no difficulties (and run one behind the GNATBOX).
You should see (or can if you've not disabled the logging) the HTTP (or other protocol) requests for the images in your log files. Start by confirming the requests are being executed and allowed by the GNATBOX. I can point you to an HTTP request sniffer tool which operates as a proxy and allows for examination of HTTP traffic if your traffic is HTTP, then you can look in detail at what is happening from your end. You may discover that the image is being sent but has format issues. Any web application is a composite of the webserver, possible application server, and the application. It is possible that your vendor's application makes some use of the IP address for security purposes. Perhaps expects the cookie to match the IP and gets upset when multiple clients and hence cookies arrive from the same IP address. If the IP address is the issue, you might setup direct mapping between external IPs and your internal machines (I'm to lazy to check the term .. tunnel?), even just for an experiment. You should get your vendor's customer support folks involved. Best if you can get the server logs from their end to correlate with your logs and investigation.
