I am trying to get a RESTful web service (JAX-RS) going with Tomcat7. I have tried 3 different implementations (Jersey, RESTeasy and Restlet) with no success. This should be easy but somehow it is not. I am looking for an up to date tutorial/documentation for annotations, web.xml and sample code.

JAX-RS applications are deployed within a standalone servlet container, like Apache Tomcat, Jetty, JBossWeb, or the servlet container of your favorite application server, like JBoss, Wildfly, Weblogic, Websphere, or Glassfish.
If the URI path template variable cannot be cast to the specified type, the JAX-RS runtime returns an HTTP 400 (“Bad Request”) error to the client. If the @PathParam annotation cannot be cast to the specified type, the JAX-RS runtime returns an HTTP 404 (“Not Found”) error to the client.
The aim of JAX-RS is to make development of Java Web services built according to the Representational State Transfer (REST) architectural style both straightforward and natural for you, the developer.
I know it has been a while since you posted this question. Most likely you figured it out by now but I would like to answer in case anyone else might benefit.
Here are some tutorials that could get you started:

If you want to create a Servlet container deployable Jersey web application use
mvn archetype:generate -DarchetypeGroupId=org.glassfish.jersey.archetypes \
-DarchetypeArtifactId=jersey-quickstart-webapp -DarchetypeVersion=2.26
