Unable to add driver redshift to JDBC driver of jasper iReport 5.6.0

[baonganptit]

Hello,

I was wondering if someone can help me figure out how to add a JDBC driver to iReport.

Here's the steps I've taken:

JasperReports 5.6.0 installed
JDBC driver JAR copied to C:Program Files (x86)JaspersoftiReport-5.6.0ide10modulesext (redshift-jdbc42-2.1.0.8.jar)
Bring up iReport. Go into Window->Services. Select Drivers, New Driver...
Add/select my JDBC JAR. I've noticed that the Find button doesn't find the Driver class even though I can see it in the JAR and I know it's an instance of java.sql.Driver.
Type in the driver class name in manually.
Try to connect using my format of the Database URL.

I'd appreciate any pointers or suggestions.
