Question

我正在使用warbler来创建我的Jruby应用程序的战争。它创建了一个没有任何问题的战争，但当我在tomcat（webapps）中部署它时，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（WEB-INF / web.xml）如下。如果我忘记配置某些内容，请告诉我。

正如第一个评论家提到的那样，由于duplicate <web-app> and <!DOCTYPE，xml无效。解析器错误与<!有关。 <!用于声明文档类型，它只能在根元素开始之前出现。任何后续出现都将被视为评论的开始。评论needs -- after <!
