运行RESTlet教程，我收到java.lang.NoClassDefFoundError

我试图运行RESTlet docs上的第一个服务器教程，但即使将罐子添加到我的类路径中，我仍然收到错误。我加入org.restlet.jar和org.restlet.ext *运行RESTlet教程，我收到java.lang.NoClassDefFoundError

服务器的代码是：

package test; 

import org.restlet.Server; 
import org.restlet.data.Protocol; 
import org.restlet.resource.Get; 
import org.restlet.resource.ServerResource; 

public class Test extends ServerResource { 

    public static void main(String[] args) throws Exception { 
     // Create the HTTP server and listen on port 8182 
     new Server(Protocol.HTTP, 8182, Test.class).start(); 
    } 

    @Get 
    public String toString() { 
     return "hello, world"; 
    } 

}

而且我得到的错误是：

什么我错过了吗？

我也得到了这些错误，因为我试图用`java -jar myprogram.jar`运行打包的jar文件，并且我没有告诉`pom.xml`文件中的maven将所有依赖关系填充到jar文件。之后，“NoClassDefFoundErrors”解决了。解决方案的概念是指示maven使用编译的jar打包依赖关系：http://stackoverflow.com/questions/1729054/including-dependencies-in-a-jar-with-maven – 2016-07-05 15:38:41

这是Eclipse的问题，我不得不删除所有的罐子，只添加org.restlet.jar并清理项目。在我做完之后，所有事情都按预期工作。

谢谢，刚刚碰到相同的问题，你为我节省了很多工作。 – 2011-02-14 01:13:16

谢谢。我在NetBeans IDE中也遇到了同样的问题。我从项目库中删除了“org.restlet.ext.httpclient-2.1m1.jar”文件，此后没有错误。

只是为了更新，从最新的restlet-jee-2.0.10/lib文件夹中只复制了org.restlet.ext.servlet.jar和org.restlet.jar。这解决了Eclipse中的问题。

在Eclipse中运行/selectableRestWebComponent/src/services/FirstServerResource.java作为Web组件。在构建路径库中仅包含org.restlet.jar。

确保您清理项目，并且您可以在eclipse项目选项卡中检查'自动构建'。

确保您有一台服务器在后台运行或附加到eclipse项目，例如Apache tomcat 6.2。

控制台应显示消息“在端口8182上启动内部[HTTP/1.1]服务器'，而不是显示您在问题中显示的所有错误。

打开浏览器并转到URL http：//'localserverIPaddress'：8182/test/tutorial，您应该看到hello，world显示的字样。
