## Problem Description

I was trying to sort a field of a document using code

`searchSourceBuilder.sort("create_date", SortOrder.DESC);`

it worked when I was debugging in my local machine, it does sort the field by descding order,

but when I am trying to deploy the project in production enviroment, I just got the exception messgag below.

I am really hope that someone can help me out of the messy.  
It troubles me for almost 2 days, thank you.

It looks like you are missing a jar. How are you adding the elasticsearch client to you application? Are you using the transport client? Which elasticsearch jars do you have?
