最开始我在代码中看到这样的代码(运行正常):
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>
但是我记得在web.xml中没有配置啊,如下:
<jsp-config>
<taglib>
<taglib-uri>mldn_hello</taglib-uri>
<taglib-location>/WEB-INF/hellotag.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>mldn_date</taglib-uri>
<taglib-location>/WEB-INF/datetag.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>mldn</taglib-uri>
<taglib-location>/WEB-INF/mldntag.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://www.mldn.cn/jst/core</taglib-uri>
<taglib-location>/WEB-INF/c.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://www.mldn.cn/jst/fmt</taglib-uri>
<taglib-location>/WEB-INF/fmt.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://www.mldn.cn/jst/fn</taglib-uri>
<taglib-location>/WEB-INF/fn.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://www.mldn.cn/jst/sql</taglib-uri>
<taglib-location>/WEB-INF/sql.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://www.mldn.cn/jst/x</taglib-uri>
<taglib-location>/WEB-INF/x.tld</taglib-location>
</taglib>
</jsp-config>
后来我在workspace search了一下,在fn.tld中发现了这么一句:
<description>JSTL 1.1 functions library</description>
<display-name>JSTL functions</display-name>
<tlib-version>1.1</tlib-version>
<short-name>fn</short-name>
<uri>http://java.sun.com/jsp/jstl/functions</uri>
我只想说四个字,原来如此。。。。。
