Question

我正在努力学习构建其他网络服务，观看Java Brains的视频。我不是仅仅遵循导师的所有内容，而是尝试将其混合起来。因此，当我在新软件包上构建新服务类但仍然收到错误Servlet.init() for servlet Second Jersey REST Service threw exception时，我遇到了这个问题。如果有人解释为什么会很高兴吗？我正在使用netbeans IDE。

这是我的web.xml：

<servlet>
    <servlet-name>Jersey REST Service</servlet-name>
        <servlet-class>

        </servlet-class>
    <init-param>
      <param-name>com.sun.jersey.config.property.packages</param-name>

<servlet>

        <servlet-class>
             com.sun.jersey.spi.container.servlet.ServletContainer

<!--New part added -->

  <url-pattern>/rest2/*</url-pattern>

<servlet>
    <servlet-name>NewServlet</servlet-name>
    <servlet-class>com.servlets.myclass.NewServlet</servlet-class>
    <init-param>
        <param-name>Name</param-name>

</servlet-mapping>

    <session-timeout>
        30
    </session-timeout>
</session-config>

这是我的新网络服务类：

 package com.service.profiles;

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



 @Path("/profiles")
 public class ProfileClass {

  public ProfileClass()
  {
  }

  @GET
  @Produces(MediaType.TEXT_PLAIN)
  public String getX()
  {
    return "Got it";
  }
}
