creating routes dynamically
Hi,
I wanted to create routes dynamically based on the msg header I receive and
send msg to that route .
This routes can grow to thousands over the period of time. And is it feasble
to have this kind of architecture?.
Regards
Sri

Yeah, reconsider your design.
and instead of
CamelContext context = new DefaultCamelContext();
the preferred way is
CamelContext context = exchange.getContext();
if you use a processor to build your routes dynamically.
Best,
Christian

Yes, you can.
CamelContext context = new DefaultCamelContext();
context.addRoutes(new RouteBuilder() {
@Override
public void configure() throws Exception {
from("direct:start1").to("log:OUT1");
}
});
context.start();
context.createProducerTemplate().sendBody("direct:start1","Hello!");
// Now add route to the running Camel context.
context.addRoutes(new RouteBuilder() {
@Override
public void configure() throws Exception {
from("direct:start2").to("log:OUT2");
}
});
// And test it.
context.createProducerTemplate().sendBody("direct:start2","Hello!");

Camel routing. My advice is to keep your integration solution as
simple as possible. Camel routing is a powerful tool, but this power
should be used wisely.
Maybe simple RecipentList[1] will match your goals?
Best regards.

I don't get this sentence, could you elaborate it a little bit?

Sri, if this is a new topic, please start a new thread with a meaningful
subject.
If this is the same topic (creating new routes at runtime which listen on
'jms:incomingData1', 'jms:incomingData2', ...), than the solution could
look like:
RouteBuilder rb1 = new RouteBuilder() {
public void configure() throws Exception {
from("jms:incomingData1")
// put your routing logic here
.to("XXX");
};
};
RouteBuilder rb2 = new RouteBuilder() {
public void configure() throws Exception {
from("jms:incomingData2")
// put your routing logic here
.to("XXX");
};
};
// and so on...
exchange.getContext().addRoutes(rb1);
exchange.getContext().addRoutes(rb2);
// and so on...
But as I mentioned before, you should reconsider such a design...
Best,
Christian

Hi ,
I have used in following way which works creating routes dynamically.
ProducerTemplate template=exchange.getContext().createProducerTemplate();
Message msg=exchange.getOut();
System.err.println("Out msg headers " + msg.getHeaders());
for(int i=0;i<3;i++){
template.sendBody("jms:incomingData"+i,
exchange.getIn().getBody());
}
may be easy one. How ever I wanted to read the messages from these routes
and But no clue how to inform this routes the which is going to be consumed?
Any Ideas
Sri

Yeah, I suggest to evaluate Dynamic Router and Recipient List for your
case. In many cases when somebody wants to create routes dynamically
at runtime, she actually needs these two patterns :) .

You could use a Dynamic Router:
