Chapter 46. Using OSGi blueprint with Camel

The XML schema is mostly the same as the one for Spring, so all the xml snippets throughout the documentation referring to Spring XML also apply to Blueprint routes.

Here is a very simple route definition using blueprint:

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0">

    <camelContext xmlns="http://camel.apache.org/schema/blueprint">
        <route>
            <from uri="timer:test" />
            <to uri="log:test" />
        </route>
    </camelContext>

</blueprint>

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0">

    <camelContext xmlns="http://camel.apache.org/schema/blueprint">
        <route>
            <from uri="timer:test" />
            <to uri="log:test" />
        </route>
    </camelContext>

</blueprint>

There are a few limitations at this point about the supported xml elements (compared to the Spring xml syntax):

However, using blueprint when you deploy your applications in an OSGi enviroment has several advantages:

To leverage camel-blueprint in OSGi, you only need the Aries Blueprint bundle and the camel-blueprint bundle, in addition to camel-core and its dependencies.

If you use Karaf, you can use the feature named camel-blueprint which will install all the required bundles.
