Tomcat上的Jruby rails應用程序。通過鶯生成的戰爭

-1

我正在使用鶯來創建我的Jruby應用程序的戰爭。它創建了一個戰爭沒有任何問題，但是當我在Tomcat中（web應用）部署它，它給了我以下異常：Tomcat上的Jruby rails應用程序。通過鶯生成的戰爭

SEVERE: Parse error in application web.xml file at jndi:/localhost/POC_Rails_1_3_1_/WEB-INF/web.xml 
org.xml.sax.SAXParseException: Comment must start with "<!--". 
    at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1231)

生成（WEB-INF/web.xml中）如下。讓我知道如果我忘記配置一些東西。

如果它是您的web.xml的確切副本，那麼顯然它是重複的，因此是一個無效的xml。刪除後的所有內容，然後重試。 – buru
