Google Glass快速入門Java HTTP錯誤503錯誤Service_Unavailable

Question

每當我嘗試在localhost：8080上運行java鏡像快速啓動主機時，我正在接受。

  HTTP ERROR: 503 
      Problem accessing /. Reason: 
      SERVICE_UNAVAILABLE 
      Powered by Jetty:// 

我正在使用mav碼頭：在命令行中運行。 我不知道我出錯的地方。我害怕解決方案將我擊中在臉上，我看不到它。

任何幫助將不勝感激提前。

Answer 1

它看起來像web應用程序無法找到一個聲明的servlet SignOutServlet。

此servlet被刪除a few commits back，它看起來像您的web.xml文件與可用的源不同步。你有幾個選項來解決此問題：

1. 創建一個新的克隆/下載的Java quick start的最新版本的壓縮文件（這可能是最簡單的解決方案）

2. 刪除對SignOutServlet所有引用如在this commit中那樣從src/main/webapp/WEB-INF/web.xml。

   <url-pattern>/attachmentproxy</url-pattern> 
   </servlet-mapping> 
   
   <!-- remove stuff below here --> 
   <servlet> 
       <servlet-name>signout</servlet-name> 
       <servlet-class>com.google.glassware.SignOutServlet</servlet-class> 
   </servlet> 
   <servlet-mapping> 
       <servlet-name>signout</servlet-name> 
       <url-pattern>/signout</url-pattern> 
   </servlet-mapping> 
   <!-- remove stuff above here --> 
   
   
   <welcome-file-list> 
       <welcome-file>index.jsp</welcome-file> 
   </welcome-file-list> 
   

一旦你刪除這些依賴關係，你建立良好的措施之前，做一個乾淨的：

$ mvn clean jetty:run
