案例環境
JBOSS4.0.5GA（Tomcat5.05）關鍵是Tomcat的版本
案例背景：
1) configure HTTPS visit
operation>> https://[server domain name]/[web-app]/
result>>> some work well, while others not
2）聯想：既然部分work well，部分not；那與配置無關。
如果做遠程映射訪問，是否是這個問題呢？
operation1>>> ssh -C -L 8080:localhost:8080 [username]@[remote server]
result>>> work well
operation2>>>ssh -C -L 12345:localhost:8080 [username]@[remote server]
result>>> some work well, while others not， the same as https
3) 逐行跟蹤：
原來是一個
2級跳的問題
以實景分析：
#####a)######
訪問 https://localhost/app/journal.do?method=journalView&companyid=001 出錯
#####b)######
定位到的出錯的語句是：
<bean:include page='<%="/journal.do?method=journalList"%>' id="outputstring"/>
<%=outputstring%>
#####c)######
直接在url里訪問這個出錯的語句，可以正常顯示
https://localhost/app/journal.do?method=journalList
#####d)######
出錯的原因

#####e)分析######
這就是說，一個.do的頁面調用另外的.do，導致出的錯；而且出錯的原因定位到bean:include標簽
#####f)解決######
采用JSTL（reference resource: 1 c.tld 2 jstl.jar 3 standard.jar)
JSP頭增加 <%@ taglib uri="/WEB-INF/c.tld" prefix="c"%>
bean:include標簽換成c:import，形式：<c:import url='<%="/journal.do?method=journalList"%>' />
#####g)原因分析######
