STS tcServer - Restful web service configuration

StackOverflow https://stackoverflow.com/questions/14310496

Question

I am trying to create a hello world restful(jersey) webservice. I am using Spring tool suite and the native vFabric tcServer.

Following is the URL : /localhost:8080/example/rest/hello which gives 404.

I have ensured all the jars are present in the WEB-INF/lib folder in the IDE.

I read through various forums which mention that all the jars should be present in the WEB-INF directory. I have been through various SO questions on the same topic but I still am unable to resolve the cause for this error.

Do I need to specifically navigate to tcServer installation in workspace to add these jars? Any ideas?

I am stuck with the following error when I start the tcServer:

Following is the web.xml:

  </servlet>
  <servlet-mapping>
    <servlet-name>jersey</servlet-name>
    <url-pattern>/rest/*</url-pattern>
  </servlet-mapping>
</web-app>

and the corresponding webservice class:

package com.example.service;

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 HelloWorldService {

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String sayHello() {
        return "whats up";
    }

    @GET
    @Produces(MediaType.TEXT_XML)
    public String sayHelloXmlVersion() {
        return "<?xml version=\"1.0\"?>" + "<hello> Hello Jersey" + "</hello>";
    }

    @GET
    @Produces(MediaType.TEXT_HTML)
    public String sayHelloHTMLVersion() {
        return "<html> " + "<title>" + "Hello Jersey" + "</title>"
                + "<body><h1>" + "Hello Jersey" + "</body></h1>" + "</html> ";
    }
}

List of all jar files in the project:

asm-3.1.jar
jackson-core-asl-1.9.2.jar
jackson-jaxrs-1.9.2.jar
jackson-mapper-asl-1.9.2.jar

Was it helpful?

Solution

Got it Fixed. Had to refer to the web project name in the web.xml: 

  .....
 <display-name>SampleWebService</display-name>
  .......

And the corresponding url: 

/localhost:8080/SampleWebService/rest/hello
