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?
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.
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.
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.
