Excetion: waiting for namespace handlers [http://camel.apache.org/schema/cxf

2016-08-26 09:19:06,451 | INFO  | -7.0.0.M2/deploy | BlueprintContainerImpl           | 28 - org.apache.aries.blueprint.core - 1.6.1 | Bundle com.xxxx.yyyyyyy.esb/0.0.1.SNAPSHOT is waiting for namespace handlers [http://camel.apache.org/schema/cxf]

When I was developing an Apache Camel REST project using CXFRS with the blueprint schema in XML DSL, above INFO log was appeared and bundle went to a Grace period. When the issue occurred my xml namespace configurations as below.

<?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" xmlns:util="http://www.springframework.org/schema/util xmlns:cxf="http://camel.apache.org/schema/cxf"     
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/cxf http://camel.apache.org/schema/cxf/camel-cxf.xsd"> 

I verified several times for the existence of the camel-cxf.xsd in the schemas of the camel-cxf dependency.

And also verified servicemix container contains the camel-cxf feature installed.

Finally I understood name-spaces and XSD locations should be as follows since I am using the blueprint schema.

xmlns:cxf="http://camel.apache.org/schema/bluprint/cxf" 

http://camel.apache.org/schema/blueprint/cxf http://camel.apache.org/schema/blueprint/cxf/camel-cxf.xsd

Then issue resolved.
