I follow exact steps in this http://www.ibm.com/developerworks/library/wa-aj-tomcat/, and I included all the jars correctly(i believe). And I still got the errors like the following:

I just did the first step, show hello. My web.xml and java file are the following:
package sample.hello.resources;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
@Path("/hello")
public class HelloResource {
@GET
@Produces(MediaType.TEXT_PLAIN)
public String sayHello() {
return "Hello Jersey";
}
}
web.xml

I have been googling for a while, I couldn't find a good solution. btw, my jar file list is: activation.jar asm-3.1.jar com.sun.jersey.jersey-server-1.4.0.jar jaxb-api-2.2.5.jar jaxb-impl-2.2_1.jar jersey-client.jar jersey-core.jar jersey-json-1.7.jar jersey-spring-1.11-b02.jar jsr311-api.1.1.1.jar stax-api.jar wstx-asl.jar
these jars are recommended on the web. I copied them directly to the WEB-INF/lib folder. One thing I'm worry about is the path issue, someone shown me before that I should add some jars by right click the class project->build path and then add jars. I tried it as well, not good news. I'm running Tomcat7.0. The web runs to a error report page as well.Please help!
I tried two local host link: 8080/Jersey/WEB-INF/web.xml & 8080/Jersey/rest/hello. both fail!
Thanks in advance.
I suspect this may be a duplicate of another question on StackOverflow. Jersey No WebApplication provider is present when jersey-json dependency added
Ultimately, make sure that jersey-server is a dependency on your classpath. When you say "your jar file list", are you certain that these jars are in the web application's classpath? It may be a function of your IDE's build path that is causing your problems.
If you still have issues, please include the IDE you use, along with how your classpath is configured.
