Description

I have attached a small sample project (using fabric3-samples-spring-restcalc project from Spring samples) that configures Camel context in Spring configuration file (META-INF/camel-context.xml) and creates a simple Camel route with Java DSL.

This is the Spring configuration for Camel:

	<bean id="properties"
		class="org.apache.camel.component.properties.PropertiesComponent">
		<property name="location"
			value="camel.properties" />
	</bean>
	<bean id="helloBean" class="org.fabric3.samples.rs.calculator.HelloBean" />
	<bean id="routeBuilder" class="org.fabric3.samples.rs.calculator.CamelRouteBuilder" />
	<camel:camelContext id="camel">
		<camel:routeBuilder ref="routeBuilder" />
	</camel:camelContext>

Even though properties bean should not be mandatory for Camel to work (actually there is no such property file even camel.properties) Fabric3 gives this error if it is missing:

[INFO main 2012-02-16 09:52:42,067] Fabric3 ready [Mode:VM, Environment: production]

When adding properties for Camel that error goes away. But we get another (even though similar and routing to the same cause I think) error later.

This is the Camel route:

from("timer:hello?delay=1000").beanRef("helloBean", "sayHello").to("stream:out");

It simply just calls helloBean.sayHello() (which returns String "hello") and routes it to System.out.

This works when run in eg. a JUnit test (test is included in attached Maven project) but when trying to deploy it to Fabric3 I get this error:

Exception in thread "main" org.fabric3.runtime.standalone.server.Fabric3ServerException: org.apache.camel.RuntimeCamelException: org.apache.camel.FailedToCreateRouteException: Failed to create route route1 at: >>> Bean[ref:helloBean method: sayHello] <<< in route: Route[[From[timer:hello?delay=1000]] -> [Bean[ref:helloBean ... because of java.lang.NullPointerException
