Jersey REST Web Service, Tomcat, Eclipse and 404's

I've read through a number of posts, but just can't seem to solve my problem. You'll also see tons of posts very similar to this one, even the same tutorial. Even following them, I can't seem to get to the answer.

Essentially, I'm trying to follow the simple tutorial at: http://www.vogella.com/articles/REST/

I've made a few changes to make it compatible with Jersey 2.x

I'm using: Eclipse Tomcat 6 (Deployed/Run as within Eclipse) jaxrs-ri-2.0 I've enabled the JAX-RS Facet in Eclipse

Everything builds fine Tomcat starts fine within Eclipse I can get to a static page content via:

http://localhost:8080/RestTEST2/index.html

However, when I try to access my service via:

http://localhost:8080/RestTEST2/jaxrs/hello

I receive a 404 with "message not found" and "The requested resource (Not Found) is not available."

Here is my web.xml which is located at /WebContent/WEB-INF/web.xml

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>TestREST2</display-name> <welcome-file-list>     <welcome-file>index.html</welcome-file> </welcome-file-list> <servlet>   <description>JAX-RS Tools Generated - Do not modify</description>   <servlet-name>JAX-RS Servlet</servlet-name>   <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>     <init-param>       <param-name>com.sun.jersey.config.property.packages</param-name>       <param-value>TestREST</param-value>     </init-param>     <load-on-startup>1</load-on-startup>     </servlet>     <servlet-mapping>       <servlet-name>JAX-RS Servlet</servlet-name>       <url-pattern>/jaxrs/*</url-pattern>     </servlet-mapping> </web-app> 

Here is my Java class:

package TestREST;  import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.Produces; import javax.ws.rs.core.MediaType;  // Plain old Java Object it does not extend as class or implements  // an interface  // The class registers its methods for the HTTP GET request using the @GET annotation.  // Using the @Produces annotation, it defines that it can deliver several MIME types, // text, XML and HTML.   // The browser requests per default the HTML MIME type.  //Sets the path to base URL + /hello @Path("/hello") public class Hello {    // This method is called if TEXT_PLAIN is request   @GET   @Produces(MediaType.TEXT_PLAIN)   public String sayPlainTextHello() {     return "Hello Jersey";   }    // This method is called if XML is request   @GET   @Produces(MediaType.TEXT_XML)   public String sayXMLHello() {     return "<?xml version=\"1.0\"?>" + "<hello> Hello Jersey" + "</hello>";   }    // This method is called if HTML is request   @GET   @Produces(MediaType.TEXT_HTML)   public String sayHtmlHello() {     return "<html> " + "<title>" + "Hello Jersey" + "</title>"         + "<body><h1>" + "Hello Jersey" + "</body></h1>" + "</html> ";   }    }  

I also have a JAX-RS User Library configured and referenced that includes all the JAX-RS jars.

Thoughts on what would cause the web service to not be found?

Does Tomcat support RESTful web services?

With these three classes coded and the Jersey libraries added to the \lib directory of the tomcat-rest-eclipse project, you can run the application on the Tomcat server and invoke their RESTful web services with a browser.

How do I run a RESTful web service in tomcat?

First, create a server run time for Tomcat 6.0 on Eclipse. This is the Web container for your RESTful Web application. Then create a dynamic Web application named "Jersey," and specify the target run time to be Tomcat 6.0.

What is Jax RS and Jersey?

JAX-RS is an specification (just a definition) and Jersey is a JAX-RS implementation. Jersey framework is more than the JAX-RS Reference Implementation. Jersey provides its own API that extend the JAX-RS toolkit with additional features and utilities to further simplify RESTful service and client development.

Jersey 2.0 does not recognize init-param with name com.sun.jersey.config.property.packages (web.xml). Try to change it to jersey.config.server.provider.packages as described in ServerProperties.PROVIDER_PACKAGES.

UPDATE (2020): try this link for current apidocs ServerProperties.PROVIDER_PACKAGES:
