Question

当我运行项目时，我在浏览器中看到一个页面“HTTP错误：503 /问题访问/WhereIsMatch.html。原因：SERVICE_UNAVAILABLE”

这是我的web.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
              http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    version="2.5" xmlns="http://java.sun.com/xml/ns/javaee">

    <!-- Servlets -->
    <welcome-file-list>
        <welcome-file>WhereIsMatch.html</welcome-file>
    </welcome-file-list>

    <servlet>
        <servlet-name>matchServlet</servlet-name>
        <servlet-class>com.kernapps.whereismatch.server.rpc.MatchServiceImpl</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>matchServlet</servlet-name>
        <url-pattern>/whereismatch/match</url-pattern>
    </servlet-mapping>

    <!-- Default page to serve -->

</web-app>

我将相应的java注释放在MatchService类上：

package com.kernapps.whereismatch.client.rpc;

import com.google.gwt.user.client.rpc.RemoteService;
import com.google.gwt.user.client.rpc.RemoteServiceRelativePath;
import com.kernapps.whereismatch.shared.domain.Match;
import com.kernapps.whereismatch.shared.domain.Matches;

@RemoteServiceRelativePath("match")
public interface MatchService extends RemoteService {
    public Match getMatch(int id);

    public Matches getMatchesCurrentRound();

}

控制台放置：

我该如何解决？

Answer 1

我不知道为什么，但是当我重新启动Eclipse时它就解决了。

使用GWT的HTTP错误503（SERVICE_UNAVAILABLE）
