BeanCreationException when starting bundle using JBoss Fuse

Question

I created maven project to expose rest web service to jboss fuse:

pom.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</build>

        <ref bean="employeeService" />
    </jaxrs:serviceBeans>
</jaxrs:server>

<bean id="employeeService" class="com.javainuse.beans.EmployeeServiceResource" />

EmployeeServiceResource.java

package com.javainuse.beans;
@Path("/")
public class EmployeeServiceResource {

public EmployeeServiceResource() {
}

@GET
@Path("/employees/{name}/")
public String getCustomer(@PathParam("name") String name) {
    return "Welcome " + name;
}

}

JBoss Fuse commands:

JBossFuse:karaf@root>install mvn:com.javainuse/apache-camel-jaxrs/0.0.1-SNAPSHOT

Bundle ID: 333

JBossFuse:karaf@root> START 333 -> give me this exception: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'restService': Initialization of bean failed; nested exception is java.lang.NullPointerException

I am using JBoss Fuse 6.3 and java 1.8

Your Maven POM needs to specify bundle as the packaging type:

<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <modelVersion>4.0.0</modelVersion>

    <groupId>com.javainuse</groupId>
    <artifactId>apache-camel-jaxrs</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>bundle</packaging>

    ...
</project>
