karaf - mongodb - com.mongodb.Mongo - ClassNotFoundException - mongodb

Question

I would like to use mongodb component in my camelContext. I have already installed feature camel-mongodb in karaf and when I do bundle:list I get
156 | Active | 50 | 2.11.3.RELEASE | MongoDB Java Driver
To show Mongo Java Drivers are installed and running.Here's my camelContext
<?xml version="1.0" encoding="UTF-8"?>

</route>
</camelContext>
<!-- Mongo DB -->

</bean>
</beans>
When I deploy this exception, I get following exception

I have also included
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>2.11.3</version>
</dependency>
in the pom.xml of my camel-bundle project
Please help me. I am not sure what is missing here.

Answer 1

I fixed this by adding the required package in the pom.xml of by camel bundle project under the <Import-Package> tag
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>1.4.3</version>
