All,
Attached is a modified "ImageJ (on Server)" component that runs on Linux, and is specialized to work when Fiji is used as the ImageJ executable. I had the "20110307" version of Fiji installed on Redhat Enterprise Linux 5.5 64-bit. Modifying this for Linux and for Fiji only required some path changes that you can find in the various subprotocols. Let me know if it works!
Cheers,
Tom Dyar
