the error message says:
unsupported major.minor version 51.0 (unable load class org.glassfish.jersey.servlet.init....) this means using java 6 vm, , try load jar containing classes built java 7. should try upgrade java7, or find/rebuild version of jersey compatible java6.
you can see @ http://en.wikipedia.org/wiki/java_class_file different major.minor values java classes, corresponding jdk versions:
j2se 8 = 52, j2se 7 = 51, j2se 6.0 = 50, j2se 5.0 = 49, jdk 1.4 = 48, jdk 1.3 = 47, jdk 1.2 = 46, jdk 1.1 = 45
