Description

When a simple java RouteBuilder that creates a component and adds it to the context in the configure method is used in a blueprint, the context cannot find the component.

Example Builder:
public class TimerRouteBuilder extends RouteBuilder {
@Override
public void configure() throws Exception

{ TimerComponent timerComponent = new TimerComponent(); getContext().addComponent("my-timer", timerComponent); from( "my-timer://test-timer") .log("Timer Fired") .to("mock://result"); }

}

Example Blueprint:
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.osgi.org/xmlns/blueprint/v1.0.0 https://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-blueprint.xsd">

<bean id="timer-route-builder" class="com.pronoia.camel.builder.TimerRouteBuilder"/>

<camelContext id="blueprint-context" xmlns="http://camel.apache.org/schema/blueprint">
<routeBuilder ref="timer-route-builder"/>
</camelContext>

</blueprint>

This test fails:
public class BlueprintTest extends CamelBlueprintTestSupport {
@EndpointInject(uri = "mock://result")
MockEndpoint result;

@Override
protected String getBlueprintDescriptor()

{ return "/OSGI-INF/blueprint/blueprint.xml"; }

@Test
public void testRoute() throws Exception

{ result.expectedMessageCount(5); assertMockEndpointsSatisfied(10, TimeUnit.SECONDS); }

}

But this test passes
public class CamelTest extends CamelTestSupport {

@EndpointInject(uri = "mock://result")
MockEndpoint result;

@Override
protected RoutesBuilder createRouteBuilder() throws Exception { return new TimerRouteBuilder(); }

@Test
public void testRoute() throws Exception { result.expectedMessageCount(5); assertMockEndpointsSatisfied(10, TimeUnit.SECONDS); }

}
