在类路径中添加库后，找不到Jetty WebSocket类 [英] Can't find Jetty WebSocket classes after adding the libraries in classpath

问题描述

我试图使用Jetty与远程服务器进行通信，使用websockets。
我在Eclipse中开发它，但是我无法编译任何示例代码。
这就是我所做的那样

I'm trying to use Jetty to communicate with a remote Server, using websockets. I'm developing it in Eclipse, but i can't compile any sample code. That's what i've done

我下载了最新版本的Jetty，我已经在classpath中添加了start.jar。
这就是我在样本类中包含的

I downloaded the latest version of Jetty, and i've added start.jar in the classpath. That's what i've included in the sample class

import org.eclipse.jetty.websocket.api.Session;
import org.eclipse.jetty.websocket.api.StatusCode;
import org.eclipse.jetty.websocket.api.annotations.OnWebSocketClose;

等等。问题是Eclipse无法解析这些导入。我应该怎么办？

and some more. The problem is that Eclipse can't resolve those imports. What should i do?

推荐答案

从你的...中删除 start.jar 项目，这只是一个启动独立Jetty分发的启动jar。

Remove the start.jar from your project, that's just a bootstrap jar for starting the standalone Jetty distribution.

您需要的JAR在$ $ c * c * / websockets / 目录。

The JARs you need are in the ${jetty.dist}/lib/websockets/ directory.

[joakim@lapetus jetty-distribution-9.0.4.v20130625]$ ls -1 lib/websocket/
websocket-api-9.0.4.v20130625.jar
websocket-client-9.0.4.v20130625.jar
websocket-common-9.0.4.v20130625.jar
websocket-server-9.0.4.v20130625.jar
websocket-servlet-9.0.4.v20130625.jar

所有WebSocket应用程序

始终包含在您的项目中：

Always include in your project:

• lib / websocket / websocket-api-9.0.4.v20130625.jar

• lib/websocket/websocket-api-9.0.4.v20130625.jar

WebSocket客户端要求

添加在您的项目之后：

• lib / websocket / websocket-client-9.0.4.v20130625.jar


• lib / websocket / websocket-common-9.0.4.v20130625.jar


• lib / jetty -io-9.0.4.v20130625.jar


• lib / jetty-util-9.0.4.v20130625.jar

• lib/websocket/websocket-client-9.0.4.v20130625.jar
• lib/websocket/websocket-common-9.0.4.v20130625.jar
• lib/jetty-io-9.0.4.v20130625.jar
• lib/jetty-util-9.0.4.v20130625.jar

WebSocket Servlet要求

如果您正在编写一个将挂接到您的WAR / WebApp的WebSocket服务器，那么您将需要：

If you are writing a WebSocket server that will hook into your WAR/WebApp, then you'll need:

• websocket-servlet-9.0.4.v20130625.jar

• websocket-servlet-9.0.4.v20130625.jar

你永远不会需要 websocket-server-9.0.4.v20130625.jar 因为这是Jetty Server用于提供对WebSockets的支持的内部/实现特定JAR。

You will never need websocket-server-9.0.4.v20130625.jar as that is an internal / implementation specific JAR that the Jetty Server uses to provide its support for WebSockets.
