Waiting for namespace handler, even though it is available.

[tellisnz]

Can anyone tell me why my bundle is entering into GracePeriod here:

camel-blueprint exposes the camel blueprint namespace:

JBossFuse:karaf@root> list | grep 135
[ 135] [Active     ] [Created     ] [       ] [   50] camel-blueprint (2.10.0.redhat-60024)
JBossFuse:karaf@root> ls 135


camel-blueprint (135) provides:
-------------------------------
objectClass = org.apache.aries.blueprint.NamespaceHandler
osgi.service.blueprint.namespace = http://camel.apache.org/schema/blueprint
service.id = 353

But my bundle is in a GracePeriod waiting for it:

14:07:14,721 | INFO  | NAPSHOT-thread-1 | BlueprintContainerImpl           | 22 - org.apache.aries.blueprint.core - 1.0.1.redhat-60024 | Bundle com.mycompany.mybundle is waiting for namespace handlers [http://camel.apache.org/schema/blueprint]
14:07:14,721 | DEBUG | NAPSHOT-thread-1 | BlueprintEventDispatcher         | 22 - org.apache.aries.blueprint.core - 1.0.1.redhat-60024 | Sending blueprint container event BlueprintEvent[type=GRACE_PERIOD, dependencies=[(&(objectClass=org.apache.aries.blueprint.NamespaceHandler)(osgi.service.blueprint.namespace=http://camel.apache.org/schema/blueprint))]] for bundle com.mycompany.mybundle

Definition of the namespace in my bundle's blueprint:

    <camelContext id="myRoute" trace="false" xmlns="http://camel.apache.org/schema/blueprint"
        xsi:schemaLocation="http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-blueprint-2.10.0.xsd">
        <routeBuilder ref="myRouteBuilder" />
    </camelContext>

This turned out to be due to having camel-core as a dependecy specified in the pom without provided scope and deploying via fab. Adding provided fixed this.

Hello Tom,

thank you for the answer. Would you mind elaborating on the details of the fix.

1. We use parent pom

2. We reference the camel-core component in the parent pom

What exactly do you want us to change. I tried adding

	<dependency>
				<groupId>org.apache.camel</groupId>
				<artifactId>camel-core</artifactId>
				<version>2.10.0.redhat-60024</version>
				<scope>provided</scope>
			</dependency>

to the POM (not the parent pom) to no avail.

Thanks in advance

Frank
