获取remoteApi GAE的超时

Question

我使用Java在Google中实现remoteAPi，方法是遵循本教程：https://developers.google.com/appengine/docs/java/tools/remoteapi

但是，在web.xml配置之后，我使用以下代码向本地数据存储插入新实体：

String username = "myusername";  
    String password = "mypassword";

    RemoteApiOptions options = new RemoteApiOptions()
        .server("localhost", 8888)  
        .credentials(username, password);
    RemoteApiInstaller installer = new RemoteApiInstaller();
    installer.install(options);

    try {
        DatastoreService ds = DatastoreServiceFactory.getDatastoreService();
        System.out.println("Key of new entity is " + 
            ds.put(new Entity("Hello Remote API!")));
    } finally {
        installer.uninstall();
    }

但出现了错误：

访问/远程应用程序/索引时出现问题。原因：

Timeout while fetching: http://localhost:8888/remote_api

我查看了调试，并知道它是由“installer.install(选项)；”语句引起的。

我怎么才能解决这个问题？增加套接字超时时间？

提前感谢！

我在本地和部署的apps.following代码中都这样做可能会对您有所帮助。请记住，代码必须用使用GWT2.4、JRE1.7和GAE1.7.2的编写。将GAE远程应用程序放入WEB/lib

web.xml

<servlet>
<display-name>Remote API Servlet</display-name>
<servlet-name>RemoteApiServlet</servlet-name>
<servlet-class>com.google.apphosting.utils.remoteapi.RemoteApiServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>RemoteApiServlet</servlet-name>
<url-pattern>/remote_api</url-pattern>
</servlet-mapping>

XyzServiceImpl.java

 @Override
public String callGaeRemote() {
    RemoteApiInstaller installer = null;
    List<Entity> allEntities = null;
    String response = null;

    try {


        RemoteApiOptions options = new RemoteApiOptions().server(
                "localhost", 8888).credentials(
                "username", "password");

        installer = new RemoteApiInstaller();
        installer.install(options);

         DatastoreService ds = DatastoreServiceFactory.getDatastoreService();
            System.out.println("Key of new entity is " + 
                ds.put(new Entity("Hello Remote API!")));
        response = "Success";           
    } catch (IOException e) {
        e.printStackTrace();
    }
    finally {
        installer.uninstall();
    }
    return response;
}
