我已经尝试了这个solution: 503 GWT error：但它没有用。

关于问题是什么的任何想法？

Answer 1

项目中的

- ＆gt;战争 - ＆gt; lib - ＆gt;的web.xml

删除 -

<!-- Servlets -->
  <servlet>
    <servlet-name>greetServlet</servlet-name>
    <servlet-class>com.proOne.server.GreetingServiceImpl</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>greetServlet</servlet-name>
    <url-pattern>/projectone/greet</url-pattern>
  </servlet-mapping>

Answer 2

java.lang.ClassNotFoundException: org.aopalliance.aop.Advice

几乎是自我解释，不是吗？你需要在CLASSPATH中使用一些“AOP Alliance”JAR。可能与Spring下载打包，或者从其pom.xml引用（如果使用Maven）。

Answer 3

如果您没有义务使用AppEngine，请将其删除！我试图使用spring和Hibernate与GWT，但它不适用于AppEngine。然后将使用的应用程序服务器将是Jetty（嵌入式服务器）。并从Build Path中删除与AppEngine相关的所有jar文件它对我有用！

Answer 4

也许您应该尝试更改项目配置中的端口。

右键单击您的项目 - ＆gt;以...运行 - ＆gt;运行配置 - ＆gt;走到服务器选项卡，并选择一个未使用的端口。

我有同样的问题，但这对我来说就像一个魅力。

什么导致我的GWT应用程序中的HTTP 503错误？
