我在页面(new.jsp)中加入
<jsp:include page= "../top.jsp " flush= "true "/>
然后用button,post到本身(new.jsp)
则会出现以下错误:

JSP Error
--------------------------------------------------------------------------------
Exception:
java.io.IOException: Unable to clear JspWriter buffer, data already written to stream.

如果不加 <jsp:include page= "../top.jsp " flush= "true "/>
则无错误, 请问该如何解决?

------解决方法--------------------------------------------------------
flush= "false "试一下
