【问题描述】：
我目前正在尝试开发 Web 服务并将其托管在 GAE 上。我继续以下步骤：
- 为 Google App Engine 创建新的 Web 应用程序项目
下面是我的课本：
*import javax.ws.rs.*;
import javax.ws.rs.Path;
import javax.ws.rs.core.MediaType;
@Path("/book")
public class Book {
@GET
@Produces(MediaType.TEXT_XML)
public String sayHello()
{
String response = "<?xml version='1.0' ?>" +
"<hello> Hello xml </hello>";
return response;
}
@GET
@Produces(MediaType.APPLICATION_JSON)
public String sayHelloJSON()
{
String response = null;
return response;
}
}*
当我在本地将应用程序作为 Web 应用程序运行时，出现以下错误。有没有人遇到过这个问题，还有，有没有人有任何方向/提示来创建一个简单的 Java Web 服务？

你没有在其他地方使用 java.util.stream.Collectors 类？
