Question

我正在尝试编译java类：http://wiki.eclipse.org/Jetty/Tutorial/Jetty_HelloWorld

使用Jetty网络服务。

出于某种原因，当我尝试跑步时：

javac -cp servlet-api-2.5.jar:jetty-all-$JETTY_VERSION.jar HelloWorld.java

它说有14个，是14个错误：

C:\Users\n...\DEMO>javac -cp servlet-api-2.5.jar:jetty-all-

        Server server = new Server(8080);
                            ^ 14 errors


How do i fix it so it works on my machine, and i can complie and run it?

Thanks.

UPDATE:
HelloWorld.java (its on the site, but ill put it here):

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.ServletException;

import java.io.IOException;

import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.Request;
import org.eclipse.jetty.server.handler.AbstractHandler;

public class HelloWorld extends AbstractHandler
{
    public void handle(String target,
                       Request baseRequest,
                       HttpServletRequest request,
                       HttpServletResponse response) 
        throws IOException, ServletException
    {
        response.setContentType("text/html;charset=utf-8");
        response.setStatus(HttpServletResponse.SC_OK);
        baseRequest.setHandled(true);
        response.getWriter().println("<h1>Hello World</h1>");
    }

    public static void main(String[] args) throws Exception
    {
        Server server = new Server(8080);
        server.setHandler(new HelloWorld());

        server.start();
        server.join();
    }
}

更新2：

在安装JAVA EE SDK的过程中。会告诉你它是否有效

Answer 1

在Windows上，你不应该使用';'而不是'：'作为路径分隔符？

Answer 2

我说你当前目录中没有jar文件C：\ Users \ n ... \ DEMO

尝试：

javac -cp C \： path \ to \ _ servlet-api-2.5.jar：C \： path \ to \ jetty-all- 7.3.0。 v20110203.jar HelloWorld.java

并替换路径......
