我试图通过JAX-RS Web服务发送JSON对象.我的文件web.xml是:

<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>jersey.config.server.provider.packages</param-name>
<param-value>it.notifire</param-value>
  </init-param>
  <init-param>
<param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
<param-value>true</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>

模拟我要发送的对象的类是:

public class GPSCoordinate {

private float latitudine;
private float longitudine;

 public float getLatitudine() {
    return latitudine;
}
public void setLatitudine(float latitudine) {
     this.latitudine = latitudine;
}
public float getLongitudine() {
    return longitudine;
}
public void setLongitudine(float longitudine) {
    this.longitudine = longitudine;
}
}

根类资源是:

@Path("position")
public class Position {

    @Context
private …

我正在尝试使用JAX-RS创建和部署RESTful Web服务并将其部署到tomcat.我不想使用任何IDE.在Tomcat中,我在webapps中有以下目录结构

notifire\WEB-INF\
                 |
                 ---> web.xml
                 |
                 ---> \classes/Notifier.class
                 |
                 ---> \lib\javax.ws.rs-api-2.0

我的web.xml包含:

<servlet>
<servlet-name>Web Service Servlet</servlet-name>
<servlet-class>javax.ws.rs.core.Application</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>Web Service Servlet</servlet-name>
<url-pattern>/webservice/*</url-pattern>
</servlet-mapping>

并且从文件Notifier.class中编译了类文件Notifier.java.

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.UriInfo;

@Path("notifier")
public class Notifier {

    @Context
    private UriInfo context;

    @GET
    @Produces("text/html")
    public String getHTML() {

         return "<p></p>";
    }
}

当我尝试访问Web服务时,http://localhost:8080/notifire/webservice/notifier我收到以下错误:

--type异常报告

--message类javax.ws.rs.core.Application不是Servlet

--description服务器遇到内部错误,导致无法完成此请求.

任何帮助表示赞赏.
