checkServer(){
        response=$(curl --max-time 20 --connect-timeout 0  --write-out %{http_code} --silent --output /dev/null localhost:8080/patuna/servicecheck)

        if [ "$response" = "200" ];
           then echo "`date --rfc-3339=seconds` -  Server is healthy, up and running"
           return 0
        else
           echo "`date --rfc-3339=seconds` -  Server is not healthy(response code - $response ), server is going to restrat"
           startTomcat
        fi
