问题描述
我有一个简单的web应用程序，托管在tomcat-7上，只有一个servlet。 servlet的目标是创建google频道，然后在打开的频道上为用户请求令牌。
WEB-INF
- lib
- appengine-api -1.0-sdk-1.4.3.jar
- classes
- Gc.class
Gc.java的来源是...
import com.google.appengine.api.channel。 *;
public class Gc extends HttpServlet {
protected void doGetPost（HttpServletRequest request，HttpServletResponse response）throws ServletException，IOException {
response.getWriter（）。write（Creating channel ...< br> ;）;
ChannelService channelService = ChannelServiceFactory.getChannelService（）;
response.getWriter（）。write（Channel created！< br>）;
response.getWriter（）。write（Getting for user'user1'...< br>）;
String token = channelService.createChannel（user1）;
response.getWriter（）。write（toekn =>+ token）;
$ / code $ / pre
但它给了我一个下面的错误...
类型异常报告
*消息* ** API包'channel'或者调用'CreateChannel ）'找不到。**
* description * **服务器遇到内部错误（找不到API通道或调用CreateChannel（））。执行此请求**
异常

**我是否缺少一些图书馆？如果是，那么哪个和哪里可以找到这些。**
任何帮助真的很感谢。
它！！！
我的应用程序的目标是在这些频道上创建Google频道并发送消息。
我的印象是，google频道API是一个独立的库，试图将相关的.jar放在我的tomcat应用程序的lib中。
但我错了。 Google频道API库仅适用于Google AppEngine服务器。因此，任何需要利用这些Google API的应用程序都必须托管在Google AppEngine Server上。
如果我错了，我很乐意听取专家的意见。 >
I have a simple web application hosted on tomcat-7 with single servlet. The aim of servlet is to create google channel and then request for a token on opened channel for a user. I have following configuration...
WEB-INF
-- lib
-- appengine-api-1.0-sdk-1.4.3.jar
-- classes
-- Gc.class
The source of Gc.java is...
import com.google.appengine.api.channel.*;
public class Gc extends HttpServlet {
protected void doGetPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.getWriter().write("Creating channel...<br>");
ChannelService channelService = ChannelServiceFactory.getChannelService();
response.getWriter().write("Channel created!<br>");
response.getWriter().write("Getting token for user 'user1'...<br>");
String token = channelService.createChannel("user1");
response.getWriter().write("toekn => "+token);
}
}
But it gives me an following error...
type Exception report
*message* **The API package 'channel' or call 'CreateChannel()' was not found.**
*description* **The server encountered an internal error (The API package 'channel' or call 'CreateChannel()' was not found.) that prevented it from fulfilling this request.**

** Am I missing some libraries? If yes then which and where can I found those.**Any help is really appreciated.
解决方案 I got it!!!The goal of my application is to create google channels and send messages on these channels.
I was under impression that, google channel API is an independent library and was tried to place relevant .jar in lib of my tomcat application.
But I was wrong. Google channel API libraries only works on Google AppEngine Server. And thus, any application needs to leverage these Google APIs must be hosted on Google AppEngine Server.
I am open to listen from experts, if I am wrong.
