apache 的配置如下

bundle the tag classes in a jar file. Make sure to include the taglib {library}.tld file located in the /WEB-INF directory
add the tag {library}.jar file to the CLASSPATH
copy the {library}.jar file to the /WEB-INF/lib directory
define the taglib element in the /WEB-INF/web.xml file. For example:
<taglib>
<taglib-uri>http://jakarta.apache.org/taglibs/{library}</taglib-uri>
<taglib-location>/WEB-INF/{library}.tld</taglib-location>
</taglib>

define the tag extension in the jsp page. The <taglib-uri> and the uri directive must match. The prefix identifies the tags in the tag library within the jsp page. For example:
<%@ taglib uri="http://jakarta.apache.org/taglibs/{library}" prefix="x" %>
