Permission denied, java web app can't read myTrustStore.jks generated by global-bundle.pem

I am unable to solve this. When I generate myTrustStore.jks file using global-bundle.pem to connect my java hibernate based application (deployed to ec2) to aws rds, the app is unable to read the myTrustStore.jks. Tried all the possible combinations but still couldn't make it work. This is the stack trace of the error I am getting. Have literally tried everything to figure it out but still couldn't get it to read the myTrustStore.jks file. Any help is always welcome.
