Servlet和JSTL在web.xml中的配置

配置如下:

<jsp-config> 

<taglib> 

    <taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri> 

    <taglib-location>/WEB-INF/c.tld</taglib-location> 

</taglib> 

<taglib> 

    <taglib-uri>http://java.sun.com/jsp/jstl/xml</taglib-uri> 

    <taglib-location>/WEB-INF/x.tld</taglib-location> 

</taglib> 

<taglib> 

    <taglib-uri>http://java.sun.com/jsp/jstl/fmt</taglib-uri> 

    <taglib-location>/WEB-INF/fmt.tld</taglib-location> 

</taglib> 

<taglib> 

    <taglib-uri>http://java.sun.com/jsp/jstl/sql</taglib-uri> 

    <taglib-location>/WEB-INF/sql.tld</taglib-location> 

</taglib> 

</jsp-config>

Servlet配置如下:

<servlet>
    <servlet-name>ExitServlet</servlet-name>
    <servlet-class>com.servlet.ExitServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>LoginServlet</servlet-name>
    <url-pattern>/LoginServlet</url-pattern>
</servlet-mapping></span>

<servlet>用来配置对象名字可以任意<servlet-name>

<servlet-class>设置所有的类要填写完整路径<servlet-mapping>

<url-pattern>映射虚拟路径是JSP所访问的路径，填写这个URL，即可进行访问。</url-pattern>
