我正在使用莺来创建我的 Jruby 应用程序的战争。它毫无问题地引发了一场战争，但是当我将它部署在 tomcat (webapps) 中时，它给了我以下异常：

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)

生成的（WEB-INF/web.xml）如下。如果我忘记配置某些内容，请告诉我。

正如第一个评论者提到的那样，xml 是无效的，因为duplicate <web-app> and <!DOCTYPE. 解析器错误与<!. <!用于声明文档类型，它只能出现在根元素的开始之前。任何后续出现都将被视为评论的开始。和评论needs -- after <!
