thanks, Willem, but that didn't improve my results.
According to the stream-caching page you referenced, the Multicast
component "will implicitly cache streams to ensure that all the
endpoints can access the message content"; setting it explicitly does
not change the behavior.
Also, the <to uri="http://0.0.0.0:9080/send/license"/> endpoint in the
route is a second instance of the service running at <to
uri="http://192.168.22.95:8135/transform-service/send/license"/> -- the
goal of this route is to recceive a service call and multicast it. The
second instance is simply running on my local machine (on a different
port than the Jetty server that's hosting my route).
To simplify the route, i dropped the multicast component, so it looks
like this:
<route id="myRoute" streamCache="true">
<from uri="servlet:///license"/>
<to uri="http://192.168.22.95:8135/transform-service/send/license"/>
</route>
When i post to the servlet, i still get the same error:
"[CamelHttpTransportServlet.service]: No consumer to service request
[POST /send/license" - to me, it looks like the request isn't reaching
the servlet.
thanks again,
Joe

First you need to cache the stream[1] for posting it across different
endpoints.
<to uri="http://0.0.0.0:9080/send/license"/> will create a producer, it
doesn't listen to the address as you want.

I'm trying to configure a multicast route that receives an HTTP POST and
POSTs it to multiple instances of a service.
From reading the documentation, the book, this list, and playing with
the camel-example-servlet-tomcat, it looks like it should be simple, but
i'm stuck.
Here's my web.xml for configuring the Camel Servlet:
<web-app>
<!-- location of spring xml files -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<!-- Camel servlet -->
<servlet>
<servlet-name>MulticastServlet</servlet-name>
<servlet-class>org.apache.camel.component.servlet.CamelHttpTransportServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- Camel servlet mapping -->
<servlet-mapping>
<servlet-name>MulticastServlet</servlet-name>
<url-pattern>/send/*</url-pattern>
</servlet-mapping>
<!-- the listener that kick-starts Spring -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<welcome-file-list>
<welcome-file>WEB-INF/index.xhtml</welcome-file>
</welcome-file-list>
</web-app>
Here's my camel context and route:
<camelContext trace="true" id="multicastCtx"
xmlns="http://camel.apache.org/schema/spring";>
<route id="multicastRoute">
<from uri="servlet:///license"/>
<multicast stopOnException="false">
<to uri="http://192.168.22.95:8135/transform-service/send/license"/>
<to uri="http://0.0.0.0:9080/send/license"/>
</multicast>
</route>
</camelContext>
The service expects data in request parameters. i can post directly to
both endpoint URIs with an http tool ("Poster" plugin for Firefox)
successfully.
However, when i post to this webapp (running in Jetty), at the URI
"http://localhost:8080/send/license"; i get a 404 error. In the Jetty
debug log, i see "DEBUG [CamelHttpTransportServlet.service]: No consumer
to service request [POST /send/license]"
I suspect i'm missing something obvious in configuring the URI for the
Camel servlet.
thanks in advance,
Joe
