<jsp-config> 包括<taglib> 和<jsp-property-group> 两个子元素。
    
    其中<taglib>元素在JSP 1.2时就已经存在;而<jsp-property-group>是JSP 2.0 新增的元素。
    <jsp-property-group>元素主要有八个子元素,它们分别为:
    
    1.<description>:设定的说明;
    2.<display-name>:设定名称;
    3.<url-pattern>:设定值所影响的范围,如:/CH2 或 /*.jsp;
    4.<el-ignored>:若为true,表示不支持EL 语法;
    5.<scripting-invalid>:若为true,表示不支持<% scripting %>语法;
    6.<page-encoding>:设定JSP 网页的编码;
    7.<include-prelude>:设置JSP 网页的抬头,扩展名为.jspf;
    8.<include-coda>:设置JSP 网页的结尾,扩展名为.jspf。


一个简单的<jsp-config>元素完整配置:

<jsp-config>
    <taglib>
        <taglib-uri>Taglib</taglib-uri>
        <taglib-location>/WEB-INF/tlds/MyTaglib.tld</taglib-location>
    </taglib>
    <jsp-property-group>
        <description>Special property group for JSP Configuration JSP example.</description>
        <display-name>JSPConfiguration</display-name>
        <url-pattern>/jsp/* </url-pattern>
        <el-ignored>true</el-ignored>
        <page-encoding>GB2312</page-encoding>
        <scripting-invalid>true</scripting-invalid>
        <include-prelude>/include/prelude.jspf</include-prelude>
        <include-coda>/include/coda.jspf</include-coda>
