camel cxfrs blueprint namespace issue

[Sriraman Gopalan <sr...@gmail.com>]

Dear All,

I am trying out a simple jaxrs service with camel 2.16-SNAPSHOT / cxf 3.1.2
and karaf 4.0.0. I am running into a problem while deploying a camel cxfrs
blueprint into karaf. The blueprint definition is as follows:

<blueprint default-activation="lazy"
	xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:cxf="http://camel.apache.org/schema/cxf"
	xmlns:camel="http://camel.apache.org/schema/blueprint"
	xsi:schemaLocation="
        http://www.osgi.org/xmlns/blueprint/v1.0.0
http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
         http://camel.apache.org/schema/cxf
http://camel.apache.org/schema/cxf/camel-cxf-blueprint.xsd
       http://camel.apache.org/schema/blueprint
http://camel.apache.org/schema/blueprint/camel-blueprint.xsd">

	<cxf:rsServer id="adapterServicesRestEndpoint"
address="/pgadmin/services/rest/"
		serviceClass="org.example.rest.impl.PGAdminRestImpl"
		loggingFeatureEnabled="true">
		<cxf:providers>
			<ref component-id="jsonProvider" />
		</cxf:providers>
		<cxf:extensionMappings>
			<entry key="json" value="application/json" />
		</cxf:extensionMappings>
	</cxf:rsServer>
	
	

	<camel:camelContext xmlns="http://camel.apache.org/schema/blueprint">
		<camel:package>
			org.example.rest.routes
		</camel:package>
	</camel:camelContext>

	<bean id="jsonProvider"
class="com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider" />

	<reference id="pgAdminRestApi"
		interface="org.example.services.rest.api.PGAdminRestApi" />

</blueprint>

Karaf Exception:

Status: GracePeriod
Blueprint
8/8/15 2:38 PM
Missing dependencies: 
(&(objectClass=org.apache.aries.blueprint.NamespaceHandler)(osgi.service.blueprint.namespace=http://camel.apache.org/schema/cxf)) 

The cxf namespace looks okay to me:
xmlns:cxf="http://camel.apache.org/schema/cxf"
The actual location of the xsd file also looks okay:
http://camel.apache.org/schema/cxf/camel-cxf-blueprint.xsd

However, I doubt the CxfNamespaceHandler is trying to pick up the xsd from
the wrong 
location:

public URL getSchemaLocation(String s) {
        return
getClass().getClassLoader().getResource("schema/blueprint/camel-cxf.xsd");
}

It should have been:

public URL getSchemaLocation(String s) {
        return
getClass().getClassLoader().getResource("schema/cxf/camel-cxf-blueprint.xsd");
}

Also, the namespace registration looks wrong in this file:
trunk
<https://github.com/apache/camel/blob/master/components/camel-cxf/src/main/resources/OSGI-INF/blueprint/camel-cxf.xml>  

The namespace registration is pointing to
<service-properties>
      <entry key="osgi.service.blueprint.namespace"  
               value="http://camel.apache.org/schema/blueprint/cxf"/>
</service-properties>

whereas it should have been:
<service-properties>
      <entry key="osgi.service.blueprint.namespace"  
               value="http://camel.apache.org/schema/cxf"/>
</service-properties>

I will try to apply the above changes to confirm if my assumptions are
right. Will update shortly.

best regards
Sriraman.

Dear All,

Apologies for the confusion.

It was my problem. The xmlns declaration in my blueprint was wrong. The
fixed blueprint header is this:

<blueprint default-activation="lazy"
	xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:cxf="http://camel.apache.org/schema/blueprint/cxf"
	xmlns:camel="http://camel.apache.org/schema/blueprint"
	xsi:schemaLocation="
        http://www.osgi.org/xmlns/blueprint/v1.0.0
http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
         http://camel.apache.org/schema/blueprint/cxf
http://camel.apache.org/schema/cxf/camel-cxf-blueprint.xsd
       http://camel.apache.org/schema/blueprint
http://camel.apache.org/schema/blueprint/camel-blueprint.xsd">
 ...
</blueprint>

best regards
Sriraman.
