This will tell us if your issue is your environment. If this works - we can rule out an environment issue.

Hey Kishore -- looks like the Java class you are using for the Sightly component cannot be found. 2 things to check: 

1 - is the helper class extend com.adobe.cq.sightly.WCMUse? 

2 - is the bundle that you placed the class in an active state? 

For those reading this thread and wanting to know how to use Sightly and Java together - see this AEM Community article: 

https://helpx.adobe.com/experience-manager/using/creating-sightly-component.html

We have more advanced Sightly ones too - for example: 

Creating a Sightly component that uses the AEM QueryBuilder API

Creating an AEM Sightly movie component

All of these show using Sightly on front end with Java on backend. 

Hope this helps
