JAR additions

We have a requirement to make use of json script and that needs jars which are added to /.../erpapp/comn/java/lib/ but when the jsp is compiled we see errors.

error: package com.fasterxml.jackson.core does not exist

import com.fasterxml.jackson.core.JsonProcessingException;

                                 ^

error: package com.fasterxml.jackson.databind does not exist

import com.fasterxml.jackson.databind.ObjectMapper;

Do we need to include this addition to any conf files and the process required to use new jars?

Found Doc ID 433241.1 but should we follow this?

Please advise.
