我正在尝试使用java,JAX-RS和Jersey重新创建用于创建REST的最优秀的vogella教程.

我正在使用带有Java-EE透视的eclipse Kepler,tomcat 7.0.

我已经创建了Todo类,带有相应注释的TodoResource类并部署在tomcat 7上.我已按照指示将jaxrs-ri库导入WEB-INF/lib文件夹.

Todo类:

package com.vogella.jersey.jaxb.model;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class Todo {
  private String summary;
  private String description;
  public String getSummary() {
    return summary;
  }
  public void setSummary(String summary) {
    this.summary = summary;
  }
  public String getDescription() {
    return description;
  }
  public void setDescription(String description) {
    this.description = description;
  }


} 

带注释的TodoResource:

package com.vogella.jersey.jaxb.model;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("/todo")
public class TodoResource {
  // This method is called if XMLis request
  @GET …
