Jetty有一個超時異常加載戰爭

Question

這是一個非常基本的例子。 我想用下面的jetty加載web應用程序。

public static void main(String[] args) throws Exception { 
    Server server = new Server(8085);  
    WebAppContext webapp = new WebAppContext("D:/workspace/camel/TestWithGradle/src/main/java/sample.war" , "sample"); 
    webapp.setExtractWAR(true); 
    webapp.setParentLoaderPriority(true); 


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

而且戰爭https://github.com/heroku/heroku-deploy/blob/master/spec/resources/sample-war.war 它是一個使用JSP文件和Java Servlet的非常簡單的戰爭。

但是，我運行此應用程序，控制檯給了例外..

請幫我精心的解釋。感謝閱讀和你的時間。

Answer 1

您的XML有一個錯誤的DTD或名稱空間聲明。

啓動嘗試從遠程URL獲取某些資源，這些資源將用於驗證XML。

這不會發生在正常的碼頭分佈或普通的碼頭瓶子工件上。

開始確保您使用的是官方碼頭罐子，不重新打包，不uberjar他們，不要一罐子他們，讓他們獨立（現在）。

然後確保您的各種XML文件中沒有錯別字。特別是在你的戰爭文件中，以及WEB-INF/lib/*.jar文件的所有內容。有可能是一個小的錯字或引用不正確，以至於Jetty無法使用碼頭罐子附帶的驗證資源來縮短該遠程資源請求。
