我正在开发一个 Java EE 项目。我想在我的 JSP 页面中添加一个图表，所以我搜索并找到了“AnyChart.jar”库。当我想在 JSP 中使用它时，我需要将一些信息写入 web.xml 部署描述符。我的描述符应该看起来像这样才能正常工作：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
    <filter>
        <filter-name>AnyChart Resources</filter-name>
        <display-name>AnyChart static resources filter</display-name>
        <description>
            This servlet filter is intended for catch http request
            to static AnyChart Component resources (AnyChart.js and AnyChart.swf)
        </description>
        <filter-class>com.anychart.servlet.ResourceFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>AnyChart Resources</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

但我已经在描述符中有一些信息：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">
    <servlet>
        <servlet-name>LoginServlet</servlet-name>
        <servlet-class>servlets.LoginServlet</servlet-class>
    </servlet>
    <servlet>
        <servlet-name>Configuring</servlet-name>
        <servlet-class>servlets.Configuring</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>LoginServlet</servlet-name>
        <url-pattern>/LoginServlet</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>Configuring</servlet-name>
        <url-pattern>/Configuring</url-pattern>
    </servlet-mapping>

</web-app>

我的问题：如何合并这两个文件以使其正常工作？我试图像这样合并它，但它不起作用：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">

    <servlet>
        <servlet-name>LoginServlet</servlet-name>
        <servlet-class>servlets.LoginServlet</servlet-class>
    </servlet>
    <servlet>
        <servlet-name>Configuring</servlet-name>
        <servlet-class>servlets.Configuring</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>LoginServlet</servlet-name>
        <url-pattern>/LoginServlet</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>Configuring</servlet-name>
        <url-pattern>/Configuring</url-pattern>
    </servlet-mapping>
    <filter>
        <filter-name>AnyChart Resources</filter-name>
        <display-name>AnyChart static resources filter</display-name>
        <description>

    </filter>
    <filter-mapping>
        <filter-name>AnyChart Resources</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <session-config>
        <session-timeout>
            30
        </session-timeout>
    </session-config>
</web-app>
