螞蟻問題上運行本地HTTP服務器

Question

我需要一個輕量級的服務器只是用於測試的目的，經過一番google搜索，我發現this答案，雖然我的文件編譯沒有任何問題，但在運行時我正在以下追溯：

源文件

package web.src.example; 

import java.io.IOException; 
import java.io.OutputStream; 
import java.net.InetSocketAddress; 

import com.sun.net.httpserver.HttpExchange; 
import com.sun.net.httpserver.HttpHandler; 
import com.sun.net.httpserver.HttpServer; 

public class Server { 
    public static void main(String[] args) throws Exception { 
    HttpServer server = HttpServer.create(new InetSocketAddress(8000), 0); 
    server.createContext("/test", new QuoteHandler()); 
    server.setExecutor(null); // creates a default executor 
    server.start(); 
    } 

    static class QuoteHandler implements HttpHandler { 
    public void handle(HttpExchange t) throws IOException { 
     String response = "Bazingaaaa"; 
     t.sendResponseHeaders(200, response.length()); 
     OutputStream os = t.getResponseBody(); 
     os.write(response.getBytes()); 
     os.close(); 
    } 
    } 
} 

Ant構建規則

<path id="classpath.server"> 
    <pathelement location="lib/http-20070405.jar" /> 
    </path> 


    <target name="server"> 
    <mkdir dir="${delivery.build.dir}"/> 
    <javac srcdir="${delivery.src.dir}" destdir="${delivery.build.dir}" includeantruntime="false"> 
     <classpath refid="classpath.server"/> 
    </javac> 
    </target> 

    <target name="runserver"> 
    <java classname="web.src.example.Server"> 
     <classpath> 
     <path refid="classpath.server" /> 
     <pathelement location="build/delivery"/> 
     </classpath> 
    </java> 
    </target> 

更新：

openjdk version "1.8.0_40-internal" 
OpenJDK Runtime Environment (build 1.8.0_40-internal-b09) 
OpenJDK 64-Bit Server VM (build 25.40-b13, mixed mode) 

更新2

有更新的jar文件我沒有收到以下錯誤後，一些問題在罐子：

java.lang.VerifyError: (class: com/sun/net/httpserver/spi/HttpServerProvider$1, method: run signature:()Ljava/lang/Object;) Incompatible argument to function 

Answer 1

你出現要使用源代碼jar，而不是包含編譯的jar類：

<path id="classpath.server"> 
    <pathelement location="lib/http-20070405-sources.jar" /> 
    </path> 

我建議從下載Maven central正確的罐子：
