Hi

I have customized /cq/page/feed.jsp per our requirement. Though I am getting following error

at the end of the feed.

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

<html>

<head><title>500 STREAM</title></head>

<body>

<h1>STREAM</h1>

<p>Cannot serve request to **************.feed on this server</p>

<hr>

<address>ApacheSling/2.4 (jetty/9.2.14.v20151106, Java HotSpot(TM) 64-Bit Server VM 1.8.0_144, Windows 10 10.0 amd64)</address>

</body>

</html>

I have been debugging it and not able to find out the reason. Has anyone come across same situation?

Thanks in advance

- Pari

Hi Pari,

This general use case RSS 2.0 . When creating your RSS feed body should not have any html or special chars. If not it will throw multiple errors when rendering on the page.

Your custom log should handle cleaning up or generating correct body for the feed.

Here is RSS feed validator. You can test your feeds generated with below link

W3C Feed Validation Service, for Atom and RSS

Thanks Manoj

I added following statement in jsp

slingResponse.getOutputStream().close();

This removed error from front end but I still see following error in error.logs Why is it happening not sure
