Jersey with tomcat giving 404 error

问题

I am using Jersey with tomacat 6 and eclipse Juno.

my file name is HelloWorldService :

package com.mkyong.rest;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.core.Response;

@Path("/hello")
public class HelloWorldService {

@GET
@Path("/{param}")
public Response getMsg(@PathParam("param") String msg) {

    String output = "Jersey say : " + msg;

    return Response.status(200).entity(output).build();

  }

}

Web.xml:

<web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</servlet>

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

when i am running my project using Apache as server- it is going to this url:

http://localhost:8080/Test/WEB-INF/classes/com/mkyong/rest/HelloWorldService.java

and i am getting 404 error.

I also tried with version="3.0" and it didn't work. Please help me out.

回答1:

you should give your url as follows;

http://localhost:8080/<your-war-name>/rest/hello/<your-param>

回答2:

The address for your example would be:

http://localhost:8080/Test/rest/hello/stranger

and this would output:

Jersey say : stranger

P.S. I guess your WAR name is Test.war and because that your deploy path is localhost:8080/Test
