Question about ajax.html examples on website
http://activemq.apache.org/ajax.html http://activemq.apache.org/ajax.html
is the link I am referencing.
The statement:
"The AMQ AjaxServlet needs to be installed in your webapplications to
support JMS over Ajax:"
I see this AjaxServlet installed in the ActiveMQ 5.4.1 install I am running.
Does this mean I must still create my own webapp to be able to use this
servlet?
I have an existing Ruby on Rails app on another port that needs to
communicate to ActiveMQ.
The Ajax Javascript clients provided must be expecting a webapp running on
the same server to function.
Am I correct? or is there something else I am missing :)
Thanks!

Yes, do not send "\n" to ActiveMQ, it thinks that those are separate messages
and breaks them up.

Using the amq-msg-type for Stomp->ActiveMQ messages from Ruby and
ActiveMQ<->Ajax to the Browser with amq.js and prototype,js
Had no problems when I did not use the header and we connected the Browser
via Orbited.
Ruby code:
javascript = render_to_string :update do |page|
page.insert_html :bottom,
"chat_message_list_#{params[:id]}", chat_message.to_html
page << "$('chat_window_#{params[:id]}_body').scrollTop =
$('chat_window_#{params[:id]}_body').scrollHeight;"
end
Orbited.send_data("CHANNEL_#{chat_message.window.workbench_id}", javascript)
Now we get 3 messages back from ActiveMQ for this single message. All this
JS has to be in one block to be run in the browser. Looking to change this
behavior back, or find a way to link these back together.
Looking thru the messages now.........

Yes, that got me amq connections. It works! The "Proxying with Apache" is a
good one.

Just curious why you're serving amq_prototype_adapter.js and amq.js from your Rails app instead of directly from ActiveMQ? Do you have local changes of some kind to those libraries? If not, I suggest just loading them from ActiveMQ itself.

As a test, this means you should be able to load http://server:8080/amq/demo/, which should be proxied to http://server:8161/demo - the path to the ActiveMQ demo application. You should also be able to load http://server:8080/amq/demo/js/amq.js and http://server:8080/amq/demo/js/amq_prototype_adapter.js.
If those URLs are working, then you'll need to use:
amq.init({ uri: "/amq/demo/amq" })
due to the default configuration in apache-activemq-5.4.2/webapps/demo/WEB-INF/web.xml:
<servlet-mapping>
<servlet-name>AjaxServlet</servlet-name>
<url-pattern>/amq/*</url-pattern>
</servlet-mapping>

This should be a request for http://localhost:8161/demo/amq?timeout=45000&d=1295668347118&r=0.3465096321093155&clientId=1295668340376
I think the adjustments I suggest above will have that effect.

Yup. You're getting the HTML content of http://server:8161/ returned to you. The amq.js code isn't getting the type of XML content it expects, and chaos ensues. The messages are coming so fast because as soon as one request returns, the client immediately initiates a new request (which is what it's designed to do).
Let me know how it goes when you're able to make those adjustments. Perhaps we should add a "Proxying with Apache" section to http://activemq.apache.org/ajax.html.

Having a little trouble following this problem report. Some more specifics would help a lot, I think.
1. Is your Ruby app Rails or something else? Running via passenger, mongrel, or other?
2. What URL do you visit to view your test web page?
3. Post the <script> tags you have in that page, and the JS code you're using to configure amq.js.
4. Post the proxy configuration you've got in Apache.
5. Post a few examples of the Apache errors you see.
6. Post a few examples of whatever is filling the Firebug log. It would be great to see a GET for polling, and the response which comes back from ActiveMQ.
Hopefully something in there will help point out what the problem is.

Re: Question about ajax.html examples on website

Going the servlet route.. Your app is running on a main server, not a virtual
one I am guessing.
Mine is virtual and with the apache config you spec'd, I understand it was a
starting point.
I have ActiveMQ 5.4.2 running on the same server. Jetty.xml is in the
activemq.xml file, so Ajax servlet should be there. Using the
amq_prototype_adapter.js.
I have a Ruby app on :8080 on that same server that serves up a page.
The page calls amq.init with "\amq" onload. Using the ProxyPass etc in
Apache with web logs set to debug.
As my GET goes out to \amq, I see in the apache logs the proxy getting setup
to from the web client to localhost:8161 then back from 8161 to /amq. There
is a body send, body end and a release. then the dame thing all over again
in the apache error_log. I can see the client cycling like mad with multiple
GETs to /amq. The Firebug log fills up in no time.
Is this something in particular with the amq.js?
Did you start at this point as well when you brought your app up with this
setup?
Trying to figure out where to go from here.
Thanks!
Phil

If you're using Firefox/Firebug, you can also do "console.log(message)" instead of "alert(message)". That will give you much more insight into what "message" is.

Ah you can send Stomp to ActiveMQ and get text back out - just add the
{'amq-msg_type'='text'} header to the stomp send and it goes as text.
Problem is now I am getting back in the response message as [object Text] in
the alert() call in the example. Using the prototype adapter and amq.js.
"received [object Text]"
How do I get the text out of the "message" here?
Can you shed some light on it?
Thanks!

I figured it out - STOMP -> ActiveMQ then ActiveMQ -> Browser with the amq.js
library is the problem.
Send and receive with amq from Browser -> ActiveMQ and ActiveMQ -> Browser
on both sides works fine.

Thanks Alex!
My config mirrors yours (Passenger,etc)
Still having issues with the demo js clients
It seems like I am asking for something from the queue that does not exist
2 Problems
1. EOFException on injection of a message to a queue
2. Web Polling via JQuery/Prototype gets empty AjaxResponses
Setup:
ActiveMQ 5.4.2 running
Ruby script to push item to a queue.

require 'stomp'

I can see the queue created and items enqueued

Problem 2:
I can see the web page polling for AjaxResponses (using both JQuery and
Prototytpe and getting empty responses

If you want to communicate with ActiveMQ from your server-side Ruby code, take a look at ActiveMessaging. http://code.google.com/p/activemessaging/wiki/ActiveMessaging You don't need the AjaxServlet to do that.
The AjaxServlet allows your clients (web browsers) to communicate with ActiveMQ. We deploy Ruby/Rails via Passenger, using Apache as the web server. Apache also serves as a proxy for ActiveMQ, so ajax requests stay in the same domain and don't violate JavaScript's same-origin policy.
This Apache configuration, in your main server config or in a VirtualHost, should get you started, though it might need to be tuned to your specific needs.
ProxyRequests Off
ProxyPass /amq http://localhost:8161 retry=10
ProxyPassReverse /amq http://localhost:8161
ProxyPassReverseCookiePath / /amq
A browser request for http://localhost/amq/ becomes a request for http://localhost:8161/.
