原因：在jsp和servlet中，调用sendRedirect()之后，如果没有return，resin中经常抛这个错！此语句前不允许有out.flush()，如果有，也会报错！

如果前面有out.println 或者 out.write 之类的，sendRedirect前也要response.getWriter().close();和out.close();！也就是说要先关闭response的输出，再进行转发！

解决方法：
response.sendRedirect("./index.jsp");
return;//在sendRedirect后面直接return

在 </cluster> 节点 的：

<!-- configures the default host, matching any host name -->
    <host id="" root-directory=".">

前面插入：

 <host id="www.javawind.net" root-directory="X:\*****\javawind.net\www">
  <host-alias>www.javawind.net</host-alias>
  <host-alias>javawind.net</host-alias>
  <web-app id="/" root-directory="."/>
 </host>

 <host id="blog.javawind.net" root-directory="X:\*****\javawind.net\blog">
  <host-alias>blog.javawind.net</host-alias>
  <web-app id="/" root-directory="."/>
 </host>

其中 红色部份表示网站所在的硬盘目录，host-alias 表示需要绑定的域名～

保存后，重启resin即可～
