The following error I am getting when deploying the application on AWS. This is working fine when the application is deployed on in house tomcat server. The location of path where it is unable to get byte contains file with proper read permisson. I am using grails drools 1.1.1 plugin with tomcat 7 and grails 2.4.4 Any help will be appreciated.

Instead of using grails drools plugin, used directly drools package through maven, which took care of this issue.
