h1. servicemix-camel

h2. Overview
The servicemix-camel component provides support for using Apache Camel to provide a full set of Enterprise Integration Patterns and flexible routing and transformation in both Java code or Spring XML to route services on the Normalized Message Router.

h3. Namespace and camel-context.xml
When creating a servicemix-camel service unit, we reuse the default Camel namespace {{http://camel.apache.org/schema/spring}}.

This is an example {{camel-context.xml}} which uses the Spring DSL to define the Camel routes
{code}
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
         http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
         http://camel.apache.org/schema/spring
           http://camel.apache.org/schema/spring/camel-spring.xsd">

          <camelContext xmlns="http://camel.apache.org/schema/spring">
            <route>
              <!-- route defined in the Spring DSL -->
            </route>
          </camelContext>

</beans>
{code}

It is also possible to use the Java DSL inside a servicemix-camel service unit by referring to the package that contains the {{RouteBuilder}} classes.  An example: this {{camel-context.xml}} file will activate all routes defined by {{RouteBuilder}}s in the {{org.apache.servicemix.example.camel}} package.

          <camelContext xmlns="http://camel.apache.org/schema/spring">
