<jsp-config>在xml版本高于2.5使用
1.下载jakarta-taglibs-standard-1.1.2.zip(在Weblogic中必须下载1.0版http://jakarta.apache.org/site/downloads/downloads_taglibs-standard-1.0.cgi)
2.解压后,将standard.jar和jstl.jar文件拷贝到\WEB-INF\lib\
3.将jakarta-taglibs-standard-1.1.1\tld\下的tld类型文件拷到"\WEB-INF\tlds"下(1.1是15个文件,1.0是8个)
4.在\WEB-INF\下建立web.xml文件:(以下<taglib>定义是针对1.0的)
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"

建立一个名为test.jsp文件
<%@ page isELIgnored="false" %>Tomcat中必须加这行,因为,默认jsp是不支持EL的.Weblogic中不能加,加了会出错!
