A.10. Static Routing Slip

Overview

The static routing slip pattern in the ServiceMix EIP component is used to route an InOut message exchange through a series of endpoints. Semantically, it is equivalent to the pipeline pattern in Apache Camel.

Example ServiceMix EIP route

Example A.19, “ServiceMix EIP Static Routing Slip” shows how to define a static routing slip using the ServiceMix EIP component. Incoming messages pass through each of the endpoints, test:procA, test:procB, and test:procC, where the output of each endpoint is connected to the input of the next endpoint in the chain. The final endpoint, test:procC, sends its output (Out message) back to the caller.

Example A.19. ServiceMix EIP Static Routing Slip

<eip:static-routing-slip service="test:routingSlip"
                         endpoint="endpoint">
  <eip:targets>
    <eip:exchange-target service="test:procA" />
    <eip:exchange-target service="test:procB" />
    <eip:exchange-target service="test:procC" />
  </eip:targets>
</eip:static-routing-slip>

Equivalent Apache Camel XML route

Example A.20, “Apache Camel Static Routing Slip Using XML” shows how to define an equivalent route using Apache Camel XML configuration.

Example A.20. Apache Camel Static Routing Slip Using XML

<route>
  <from uri="jbi:endpoint:http://progress.com/demos/test/routingSlip/endpoint"/>
  <to uri="jbi:service:http://progress.com/demos/test/procA"/>
  <to uri="jbi:service:http://progress.com/demos/test/procB"/>
  <to uri="jbi:service:http://progress.com/demos/test/procC"/>
</route>

Equivalent Apache Camel Java DSL route

Example A.21, “Apache Camel Static Routing Slip Using Java DSL” shows how to define an equivalent route using the Apache Camel Java DSL.

Example A.21. Apache Camel Static Routing Slip Using Java DSL

from("jbi:endpoint:http://progress.com/demos/test/routingSlip/endpoint").
    pipeline("jbi:service:http://progress.com/demos/test/procA",
             "jbi:service:http://progress.com/demos/test/procB",
             "jbi:service:http://progress.com/demos/test/procC");
