How to add Redshift Driver to JasperSoft Studio Stand alone application

Hello ,

I am using JasperSoft Studio first time.

I have successfully installed JasperSoft Studio on my Windows EC2 Server, I am trying to connect to my Redshift Cluster but I am getting pop-up with the following error :

java.lang.classnotfoundexception : java.lang.classnotfoundexception cannot be found by.....

I tried adding Redshift Driver which I downloaded from AWS , in the Driver Classpath in JasperSoft Studio, but still I am getting the same error.

How to solve this issue .

Thanks.
