如何隐藏.jsp扩展名或更改URL上的显示名称？

我正在使用servlet-jsp通信。我的web.xml代码是

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
    <servlet>
        <servlet-name>pub</servlet-name>
        <jsp-file>/publications.jsp</jsp-file>
    </servlet>
    <servlet-mapping>
        <servlet-name>pub</servlet-name>
        <url-pattern>/publications</url-pattern>
    </servlet-mapping>
    <servlet>
        <servlet-name>SciArchive</servlet-name>
        <servlet-class>controller.SciArchiveController</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>SciArchive</servlet-name>
        <url-pattern>*.sci</url-pattern>
    </servlet-mapping>
    <welcome-file-list>
        <welcome-file>home.jsp</welcome-file>
    </welcome-file-list>
</web-app>

我想在网址中隐藏.jsp扩展名..../SciArchive/publications.jsp
以..../SciArchive/publications
