本文介绍了运行RESTlet教程，我收到java.lang.NoClassDefFoundError的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试在RESTlet 文档，但是即使我将jar添加到我的类路径中，我也遇到了错误.我添加了org.restlet.jar和org.restlet.ext.*
I'm trying to run the first server tutorial on RESTlet docs but i'm getting errors even though i added the jars to my classpath. I added org.restlet.jar and 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:

WARNING: No available server connector supports the required protocols: 'HTTP' . Please add the JAR of a matching connector to your classpath.
我想念什么?
推荐答案
这是Eclipse问题，我不得不删除所有jar，仅添加org.restlet.jar并清理项目.完成后，一切都按预期进行.
It was Eclipse problem, i had to remove all the jars and only add org.restlet.jar and also clean the project. After i did that everything worked as expected.
这篇关于运行RESTlet教程，我收到java.lang.NoClassDefFoundError的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
