运行RESTlet教程，我收到java.lang.NoClassDefFoundError

标签： restlet restlet-2.0

我正在尝试在RESTlet docs上运行第一个服务器教程，但即使我将jar添加到我的类路径中，我也会收到错误。我添加了org.restlet.jar和org.restlet.ext。*

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";  
    }  

}

我得到的错误是：

我错过了什么？

4 个答案:

答案 0 :(得分：9)

这是Eclipse问题，我不得不删除所有的jar并只添加org.restlet.jar并清理项目。在我这样做之后，一切都按预期工作。

答案 1 :(得分：0)

感谢。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，从那时起没有错误。

答案 2 :(得分：0)

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

答案 3 :(得分：0)

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

确保清理项目，然后您可以检查自动构建＆＃39;在eclipse项目选项卡中。

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＆＃39;在端口8182上启动内部[HTTP / 1.1]服务器＆＃39;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：//＆＃39; localserverIPaddress＆＃39;：8182 / test / tutorial，你会看到单词hello，world shows。
