Subject [jira] [Commented] (AMQ-3585) CLONE - ajax client does not receive all messages
Date Thu, 10 Nov 2011 08:00:52 GMT


Edmond Kemokai commented on AMQ-3585:

Looks like this issue is back. I am using 5.5.1 and it seems to be using a different mechanism
for managing pending messages. Specifically it is using the UndeliveredAjaxMessage object.
It seems this new implementation caused the problem to reappear.

>    Affects Versions: 5.4.2
>         Environment: OSX 10.6 on MacBook Pro
> java version "1.6.0_20"
> Java(TM) SE Runtime Environment (build 1.6.0_20-b02-279-10M3065)

>         Attachments: all_messages_are_delivered_to_ajax_clients.2.patch, all_messages_are_delivered_to_ajax_clients.patch,
chat-send.html, include-commons-httpclient-in-pom-xml.patch
> Not all messages written to a destination are delivered to an ajax client.  This seems
particularly true if more than 1 message should be returned to a client at once.  Often, if
5 messages are available, only the first 1 is actually returned in the <ajax-response>
XML.  The other 4 are lost.
> Steps to reproduce:
>  * Place the attached chat-sent.html in activemq/webapps/demo/  (or in activemq-trunk/activemq-web-demo/src/main/webapp
in an svn working copy).
>  * Start ActiveMQ.
>  * Browse to http://localhost:8161/demo/chat.html & join the chat room.
>  * In a new window, browse to http://localhost:8161/demo/chat-send.html
> chat-send.html will send 5 message to topic://CHAT.DEMO.  Only 1 (or sometimes 2) messages
will be received by the original browser window which is subscribed to the topic.  The activemq
web admin will verify that 5 messages were actually sent.
