I had a problem running the Admin console on a Headless Mac Mini Server running Lion Server and FMS Advanced version 12.03. The main problem was that the Admin console was blank. For details see https://fmdev.filemaker.com/message/103694#103694.
I was able to work out removing Java 7 and getting Java 6 installed and mostly functional. At this point, when I open the web admin screen http://fmserver:16000 I get a message that the FileMaker Server Admin Console requires a supported version of Java, Click here to install java. Clicking on the link brings me to the Oracle download page. Where I can only get Java 7. I have a notebook running Snow Leopard that still only has Java 6 installed. When I open the Web interface on this system, it shows me the Start Admin console button and works normally. It seems that the installation of Java 7 messes all of this up.
Does anyone know a way to get web interface to correctly accept the version of Java 6 installed on the server. Installing Java 7 makes it impossible to run the Admin console without a monitor installed. If a monitor is installed, then I can't connect a disk to the thunderbolt port to back the server up. Not to mention that it was intended to run with out a monitor.
Thanks much for any assistance with this.
