在Tomcat環境下，web.xml設定 Page Encoding

在web.xml開頭：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

在web.xml中的jsp-config加入：

<jsp-config>
 <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>Big5</page-encoding>
  <scripting-invalid>false</scripting-invalid>
  <include-prelude></include-prelude>
  <include-coda></include-coda>
 </jsp-property-group>
 <jsp-property-group>
  <description>Special property group for JSP Configuration JSP example.</description>
  <display-name>JSPConfiguration</display-name>
  <url-pattern>*.html</url-pattern>
  <el-ignored>true</el-ignored>
  <page-encoding>Big5</page-encoding>
  <scripting-invalid>false</scripting-invalid>
  <include-prelude></include-prelude>
  <include-coda></include-coda>
 </jsp-property-group>
</jsp-config>
