这里的request不知道和我理解的request一样不<%@ page contentType="text/html;charset=gb2312" %>
<% request.setCharacterEncoding("gb2312"); %>
这些地方都注明了简体中文，我觉得最好就是用utf-8，国际通用，只是个建议，跟你的问题可能没关系
System.Web.HttpUtility.UrlEncode(System.Text.Encoding.UTF8.GetBytes(string a ))
chStr str = new chStr();
register.name = str.chStr(request.getParameter("txtname"));

str.chStr(register.userName),,,,,
JAVABEAN+JSP,我没用过多少,不是很熟,不过为什么还要这样取得呢？
会不会是数据库里乱码了．如果是ＭＹＳＱＬ很有可能.
<% //获取用户名
register.userName=request.getParameter("txtusername");
register.setConnection(dbconn.getConnection());
//判断用户名是否已经存在
if(register.isExist()){
System.out.println("该用户已经存在");
}
这里打印看看是什么东西,有没有乱码.
<filter-name>encoding</filter-name>
<filter-class>com.jspdev.ch8.EncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>gb2312</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
看下数据库里存的字段值是不是"??"，mysql对中文的支持很差建议你在建表的时候就设置字符编码DEFAULT CHARSET=GBK;
