Communication between two processes without using external
messaging systems or files
Hi,
We have a requirement where we are having two processes. The output of one process will be the input for the second one. We do not want to use the external messaging systems like active MQ etc and also we do not want to use file component.
We want something like first process will dump the message in some internal queue(or something else) and the second process will be polling this queue for the messages.
Is there any component available in camel to achieve this requirement.
Thanks in advance.
Regards,
Shadab

I'm not sure if it is possible, but perhaps you can do it with a quartz poller doing an enrich from a direct endpoint.
Something like this (out of my head)
from("direct:processOne")
.to("direct:processTwo");
from("quartzPoller")
.pollEnrich("direct:processTwo")
.bean(otherProcessors...);
http://camel.apache.org/content-enricher.html
http://camel.apache.org/quartz.html
It's perhaps something to try.
Otherwise I also believe you'll have to use some external mechanism (jms, file, database).

hi Shadab,
it really sounds like you really should be using ActiveMQ. You can run it embedded - collocated with your producing process - and you don't need to use persistence
see here how to set it up - http://activemq.apache.org/how-do-i-embed-a-broker-inside-a-connection.html and here's an example with camel - http://camel.apache.org/walk-through-an-example.html
I know you don't want to use ActiveMQ - but the best way to do what you want is actually with ActiveMQ :)
thanks,
Rob

OK - understood in which case both Christian and Charles' suggestions are best -
look at http://camel.apache.org/direct.html - for the a good example of chaining routes together and SEDA - http://camel.apache.org/seda.html

Hi Robert,
With two different processes I mean two different camel routes.

Shabad,
If you don't want to use a JMS broker, then you should consider to use
camel seda component (http://camel.apache.org/seda.html) which uses an
internal queue (
http://docs.oracle.com/javase/1.5.0/docs/api/java/util/concurrent/BlockingQueue.html)
for async exchange. For sync exchanges, then direct must be used (
http://camel.apache.org/direct.html)
