[opencms-dev] Flush JSP output buffer in formatter

[Alexander Kandzior]

You may try to set the "cache" property to "stream" or "bypass". 

 

IIRC this needs to be set at the template JSP. I can't say if this features
works with formatters, I did not use this for a long time.

 

It still is in the code though:

ader/CmsJspLoader.java#L502

 

A short explanation in the documentation:

e/streaming.html

 

 

Kind Regards,

Subject: [opencms-dev] Flush JSP output buffer in formatter

 

Hello there, 

 

I'd like to find out if there is a way to flush the JSP output buffer to the
user's browser in a formatter jsp.

I have a situation where I have a very long search result list that's coming
from an external web service and it only gets flushed after the whole page
is rendered, but I'd like to flush after say five or ten result rows. 

I've tried about every flushing method known to me, none of them did do any
good. 

Here are some of the things I tried:

 

  out.flush();

  flexController.getCurrentResponse().flushBuffer();

  flexController.getCurrentResponse().getOutputStream().flush();

  flexController.getCurrentResponse().getWriter().flush();

  flexController.getTopResponse().flushBuffer();

  flexController.getTopResponse().getOutputStream().flush();

  flexController.getTopResponse().getWriter().flush();

 

Any ideas?

Does anyone know how OpenCms handles the rendering of formatters internally?


Is there any way at all to flush formatter output during rendering?

 

Cheers

 

Kai

 

P.S.: I know that something like this could easily be done using AJAX and
lazy loading. But let's just assume I'm not allowed to use AJAX.
