</P>
<P>##############################<BR>直接调用GB2Big5只适用于对于少量字符的转化，当需要对整个jsp页面根据用户需要进行编码转化<BR>的时候，就需要使用到taglib的功能。<BR>具体配置使用步骤如下：</P>
<P>1.在WEB-INF/目录下增加GB2Big5Wrapper.tld文件，内容如下: <TEXTAREA class=xml name=dp_sourcecode rows=20 cols=60><?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE taglib
PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN"
"http://java.sun.om/dtd/web-jsptaglibrary_1_2.dtd">
<taglib>
<tlib-version>1.0</tlib-version>
<jsp-version>1.2</jsp-version>
<short-name>zealLi</short-name>
<tag>
<name>GB2Big5Wrapper</name>
<tag-class>zeal.util.GB2Big5Wrapper</tag-class>
<attribute>
<name>isbig5</name>
<rtexprvalue>true</rtexprvalue>
<type>boolean</type>
</attribute>
</tag>
</taglib>
</TEXTAREA>
<SCRIPT language=javascript
src="繁简体(GB=Big5)字符串转化的JAVA方式实现 Zeal Blog - 泽欧里的网络日志.files/shBrushXml.js"></SCRIPT>
</P>
<P>2.在需要进行转化的JSP页面里面加上:<BR><%@ taglib uri="/WEB-INF/GB2Big5Wrapper.tld"
prefix="zealLi"%><BR><zealLi:GB2Big5Wrapper
isbig5="true"><BR>任何你需要转化的东西<BR></zealLi:GB2Big5Wrapper></P>
<P>比如test.jsp源代码如下 => <TEXTAREA class=xml name=dp_sourcecode rows=20 cols=60><%@ page
contentType="text/html; charset=GBK"
import="javax.servlet.http.HttpSession"
import="java.util.*"
import="com.zealLi.*"
%><%
String encode = request.getParameter("encode");
if(null == encode || encode.length() <= 0){
encode = "BIG5";
}
boolean isBig5 = false;
String charset = "GB2312";
if(encode.equalsIgnoreCase("BIG5")){
isBig5 = true;
charset = "BIG5";
}
String sInfo = "中文字体繁简体转化的测试。";
%><%@ taglib uri="/WEB-INF/GB2Big5Wrapper.tld" prefix="zealLi"%>
<zealLi:GB2Big5Wrapper isbig5="<%= isBig5 %>">
<html>
<head>
<title>Jsp测试页面</title>
<meta http-equiv="Content-Type" content="text/html; charset=<%=charset%>">

<body>
<%
Calendar now = Calendar.getInstance();
out.println(now.get(Calendar.YEAR) + "." +
(now.get(Calendar.MONTH)+1) + "." +
now.get(Calendar.DAY_OF_MONTH) + "<p>");
%>
