Oracle Libs under Ubuntu 14.04

Im finish a webapp and need do deploy it on Ubuntu 14.04 server. I already have installed oracle instant client and I could access sqlplus64 without any error. The libs installed of the instant client it is version 11.

When I execute on termina in order to launch the webapp this error shows up:

Failed to load plugin cannot open shared object file: No such file or directory

I am using instant client version 11 because I am connect to a Oracle Enterprise 11g.

Also I not found any help about how to manage xojo+oracle requeriments. Can someone that already pass this issue help me?
