I've also tried installing the one click VNC app through the amahi app page on a fresh Desktop install, and get the same error when using the java VNC client... Connection refused:connect

I have a similar problem, in that I have a new installation of Ubunto/Amahi and selected the VNC application from the control panel and installed it. The control panel says that the server is running, but when I try to access my HDA from a Windows java client, it says that the connection was refused...
