关于WEB.XML文件的问题。回答有分～～～～～

Question

这是当然了，servlet,ejb都要写入到此文件中

Answer 1

目录结构：
webapp-->WEB-INF-->classes
                -->lib
                -->web.xml
      -->你的jsp文件。
从examples中copy一个web.xml过来就行了

<?xml version="1.0" encoding="UTF-8"?>

    </servlet-mapping>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>index.html</welcome-file>

</web-app>
大体格式如此，创建web.xml文件放在 WEB-INF目录下旧可以了
