Can anyone help me.

have you installed python on your machine? In tutorial it is mentioned to install python — Vishal John, Aug 06 '14 at 07:36
Yes, I have installed python but still I feel python only causing the problem. The resources folder files are not getting loaded properly — bharathi, Aug 06 '14 at 08:15

I had the same error. Look at the compiled source. In the target folder you need all the scripts of the mutlilang available to execute all of them.

Look at target/classes/resources/ if there are any files. If not and if even you do not have the folder in target/classes copy the the resource folder from multilang/resources into the target path.
