Answer 1

the below part of error suggests that you are using unsupported version of Jersey. Please check and use an appropriate version.

 Caused by: java.lang.UnsupportedClassVersionError: 

org/glassfish/jersey/servlet/init/JerseyServletContainerInitializer : 

Unsupported major.minor version 51.0 (unable to load class 

Version 51.0 corresponds to Java 7. Are you starting tomcat with a version below Java 7?
