Java isn't installed, or isn't installed properly. Repeat the installing java steps in this tutorial and try again maybe..
aha ... thank you for thatAlso, .oanda (like any folder with "." infront) is a hidden folder, so a regular file browser will hide it by default. You Linux home directory is likely full of folders like this. No biggy.
Tom looks like Java isn't installed or in the PATH environment variable (which the linux machine will search to find programs). I assume that the fxTrade application doesn't bundle java with it.The program 'java' can be found in the following packages:
find / -type f -name java 2>/dev/null
