client side http post without a web server
Hi, I am new to activeMQ, is there a way to do a http post without a web
server invloved?
My situation is I have a java application running on the client machine with
an embedded broker (the example embedded broker), the application is
subscribing to a queue(the example consumer). At the same time, there is a
web page on the client machine which needs to communicate with the java
application by sending a message to the queue using java script. All these
actions happen on a same local machine without a web server involved due to
firewall restrictions.
I have browsed throught the website and set up the example embedded broker
and example consumer to work, however, the example web demo is utilizing a
web server(client web page post back to the server and then the server talks
to the queue), while what I need is the client web page post directly to the
queue.
Here is my java script code which does not work
var oXMLHTTP = new ActiveXObject( "Microsoft.XMLHTTP" );
var sURL = "http://localhost:61616/queue/TEST/FOO"
oXMLHTTP.open( "POST", sURL, true );
oXMLHTTP.setRequestHeader("Content-type","application/x-www-form-urlencoded");
oXMLHTTP.send("This is the JMS message");
Thank you !!

Thank you for the reply Chris.
I will try jetty or modify the embedded broker code to allow it parse http
requests.

Jetty is embeddable, and is configurable via api calls, so it can
run inside your existing client-side Java application (as Guillaume
suggested) without too much fuss. Although Jetty is technically
a full-blown HTTP server, you don't have to use it that way.

Can the embedded broker parse the incoming http request and post the message
to the queue? It does not need to be a full blown http server, it just needs
to be a socket server with the capability to parse http post requests.
It may not make much sense most of the time, but it can come handy for
certain cases.

How else do you propose to deal with HTTP without at least a Java
library which actually parses HTTP like Jetty?

No - the http and ajax connectors for ActiveMQ depend on at a minimum
a servlet engine and typically Jetty which is a pure Java web server.
By definition if you are reading http then you are a web server so
its pretty hard to avoid it :)

You could launch some java code in an applet, or use a javascript stomp
client
(I don' t think one has been written yet).
Or start a jetty web server colocated with your local activemq broker and
post to it.
In all cases, if you want to use HTTP, you need an http server to parse and
process
the request. Jetty is the really good candidate here.
