Direct Component
The direct: component provides direct, synchronous invocation of any consumers when a producer sends a message exchange.
This endpoint can be used to connect existing routes in the same camel context.
Asynchronous
The Seda component provides asynchronous invocation of any consumers when a producer sends a message exchange.
Connection to other camel contexts
The VM component provides connections between Camel contexts as long they run in the same JVM.

Samples
In the route below we use the direct component to link the two routes together:
from("activemq:queue:order.in").to("bean:orderServer?method=validate").to("direct:processOrder");
from("direct:processOrder").to("bean:orderService?method=process").to("activemq:queue:order.out");
And the sample using spring DSL:
<route>
<from uri="activemq:queue:order.in"/>
<to uri="bean:orderService?method=validate"/>
<to uri="direct:processOrder"/>
</route>
<route>
<from uri="direct:processOrder"/>
<to uri="bean:orderService?method=process"/>
<to uri="activemq:queue:order.out"/>
</route>
See also samples from the Seda component, how they can be used together.
