There are maybe different results in different implements of c. but in the platform of java, i=0 is the only answer.
Anyway, if you find code like this in your project, the author must be a bad guy. He may try to play a trick or want to bury this project!

I have a Encodefilter which runs well on struts + tomcat4.
[Encodefilter]
...
request.setCharacterEncoding(encoding);
response.setContentType(contentType);
...
Now I start a new projection bases on webwork + hibernate + tomcat5.
I use the Encodefilter as a filter to url /*,and write a jsp like this:
[JSP]
<%@page contentType="text/html" %>
<%@page pageEncoding="GBK"%>
...
<META HTTP-EQUIV="content-type" CONTENT="text/html; charset=GBK">
...
The page can show chinese and english,but can't pass the chinese request parameter(it show the chinese with "???").
I watch my console,I find before the Encodefilter's doFilter(),the param is
already "???".
I don't know what's wrong.Is webwork or something else?

I meet a question with jb9.
When I code in jb8,there's package codeinsight.
When u type java and then type ".",a pop-up
window show some package like util,sql and text.
But I can't find this feature in jb9(or sth
of my pc is wrong?).In the jb9,other codeinsight
are ok(like method and parameter).
Can anybody explain this???
After 3 days,reply cames.First much thank Philip Shanks.
I also use the tomcat-user.xml to manager the user and role through security realm.
I want to know whether there is any better means to implement the user-role in the struts.

I have 100 users along with their roles in database.
I have 100 functions in my web application.(for example,100+ org.apache.struts.action.Action)
The users and their roles often change(after one or two months)
How can I implement this role_based authorization (in struts1.1)?
Also I can extend a base action with authorization or implement the processRoles in the org.apache.struts.action.RequestProcessor,but I don't want to modify my java code or jsp after one or two months.
Please help me!

I create a new struts lib and remove the old one(
if there are two struts frameworks,the web appli-
cation will add two struts-config.xml files,is it
a bug?).Then I modify the dtd of struts-config
.xml.It's ok.
16 years ago
I modify the doctype of the struts-config.xml
(http://jakarta.apache.org/struts/dtds/struts-
config_1_0.dtd - > http://jakarta.apache.org/struts/dtds/struts-
config_1_1.dtd)
If anybody has some better way?
