Answer 1

There are two possibilities here. 1. You are getting an exception. Log statement inside the catch block could prove that. 2. The M150_DESCRIPTION column in table is null

Answer 2

Most probably you are not able to establish db connection . Firstly check the db connection and then check whether your query is returning any result or not.
