Hi,

If flush attribute set to true. The JspWriter ( out) is flushed before the include action. That is the buffered contains (if any) are written to the client.

Suppose the following JSP codes

  
This contents are displayed on browser before the jsp:include invocation.
<jsp:include page="jspaction2.jsp" flush="true"/>

It the flush is set to false which is default. Then the contents prior to the action may be sent to brower depends on the buffer size.

Thanks

Hi Narendra,

But the things are not happening as u said in Tomcat5.0?

The template text or some info before the jsp:include with flush=true is also being sent to the client.

Hi,

How you notice when the contents are send to the browser. In any case they are displaying into the browser as include will not clear the content of the calling page. In case the flash='true', the contents will send immidiately before the include call. In case of flush='flase' , the contents will be send after the buffer is full or response is closed or manually flushed.

You will notice the difference when you have some long processing in the included page and then writing the response.

Thanks

Thanx Narendra.
My doubt got rectified.

I thought flushing means i will discard the output generated by
the parent page.
