Tomcat itself doesn't use 100% CPU, it is not designed that way. Most probably it is some application that is deployed on it. To make 100% sure that it's not Tomcat just download its distribution and start it up - I bet you CPU usage will be closer to 0.

To tell which application inside your Tomcat is misbehaving you will need to use profiling tools.

The best one IMO is Oracle's VisualVM. Start it from your JDK bin directory (it is called jvisualvm.exe), then follow the guide at the link. In particular its Profiling section.
