BusinessRuleTask in Activiti 1.9


I am new to Activiti and started working with this recently. I have a situation here I am trying to include some business rules using Drool and Activiti BusinessRuleTask, I have done the below steps to achieve the same:

1. My Activiti installation is running on Tomcat 8.5 and Activiti Ver is 1.9

2. I have created a process model using the activiti process modeler portal. 

3. I have created one java project and using a Delegate class to prepare a object(for eg. LoanApplication) which I am going to use as input to my rule. 

4. I have added the .drl file with the rule in my project class path. 

5. I created one jar file and deployed it in activiti-app/WEB-INF/lib folder.

6. I have deployed the sample process model app using Activiti Process Modeler portal (UI). 

7. While starting the process using the Activiti UI I can see the process app is not able to find the rule and getting the error "org.activiti.engine.ActivitiException: deployment 62514 doesn't contain any rules"

which is very certain that it is not able to find the .drl file although it is present in the activiti-app/WEB-INF/lib/myjavaproj.jar file. Looks like I need to put it in somewhere else where the process model .xml file resides but with the installations I have all the details are being stored in db. 

Can someone put some light on this how to resolve this and where I should keep the .drl files so that process should pick them up ? 

Thanks in advance.
