The problem is here:

Unsupported major.minor version 51.0 (unable to load class com.mytest.testws.services.Service)

That means you have compiled that class with a different (higher) Java version than your Tomcat supports. As I can see you are using Tomcat 6.0.35, therefore you need to compile your service with JDK 5 (or lower). Here is a table showing you which Tomcat versions support which Java version.

In Netbeans click 'Tools' -> 'Java Platforms' and define a JDK 5 or update Tomcat to a higher version.
