How to use unique queue for different camel-vm endpoint
Hi Guys,
I am working on a project that requires using multple camel-vm endpoints.
See an example of my flow:
camelContext-vm-endpoint 1 = A
camelContext-vm-endpoint 2 = B
camelContext-vm-endpoint 3 = C
When I send a message from A -> B -> C
when C returns with a response, the response is sent to A and B
simultaneously as well i.e. instead of only C to get the response, and then
send its response to B and B sends to A in that order, all A,B,&C gets the
response at once.
How can I avoid this?
Regards.

Its the simple pipeline pattern.
I have differnt osgi bundles (camel application), which are exposed as
endpoints to Servicemix as vm endpoints. Each of them do a specific
function.
I am just calling each function in a sequential order.
e.g. endpoint A - is a REST protocol consumer
endpoint B - is a functional component that verifies order (it listens on
the ESB using the vm component)
endpoint c - is a functional component that processes order (it listens on
the ESB using the vm component)
endpoint D- is a service provider (it listens on the ESB using the vm
component)
so, when A receive a request over REST, it sends 2 endpoint B through vm,
and B forwards to C and C to D through vm as well. The problem is, when D
returns a response, both B, C gets the response from D and returns, instead
of C only to get a response from D and B to get response from C.
Regards.
But the problem is, when C fin

Naira-
Can u describe in a little more detail the process you are trying to implement? Perhaps there is a pattern better suited for your assignment.
Thanks,

What version of Camel are you using?
camel 2.2.0
Have you actually looked at the SEDA/VM documentation which has a warn
about using multiple VM/SEDA queues?
http://camel.apache.org/seda
http://camel.apache.org/vm
I read those pages before making this post and I didnt see any such thing
about multiple VM/SEDA queue.
MultipleConsumers is not enabled by default (according to the doc), and so I
did not expect messages to be sent to multiple consumers.
Kindly point me in the right direction if I have used this component the
wrong way.
Regards.
