Tomcat SSL keystore loading error

I am a noob trying to set up SSL in localhost eclipse tomcat using openssl. Used the below commands

1. created key.pem and cert.pem

   openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 999

2. created crt file using

   openssl x509 -outform der -in cert.pem -out mycert.crt

3. Added the below connectir tag to tomcat server.xml

When i access https://localhost:8443, tomcat console shows SEVERE: Failed to load keystore type JKS with path /root/.keystore due to /root/.keystore

Can anybody point out what i have to do correct this error and to gain accces to https://localhost:8443 ?
