Re: Can I route OSGi calls in SMX4?

[Gert Vanthienen <ge...@skynet.be>]

Juan,

If you register an endpoint for your service in the NMR, you can access 
it from you camel orchestration bundle.  The camel-nmr shows you how 
different Camel routes can communicate over the NMR, but you can connect 
anything there.  A service that has an endpoint registered on the NMR, 
is not necessarily available for remote calls.

Whether or not you expose a service to remote calls, is entirely up to 
you.  Many applications only expose a few (web)services to the outside 
world, while working with a lot of different services for the 
implementation. 

For the log: endpoint, that actually refers to a Camel component 
(http://activemq.apache.org/camel/log.html) which uses the 
commons-logging API.  The only thing OSGi does here is provide the 
classes from the logging bundle to the camel-core bundle.  If this is 
what you want to, just take a look at any components in Camel for an 
example. 

Regards,

Gert

Hi Gert,

First of all, thank you so much for helping me. Now I have a better
understanding of NMR.

But, how can I register an endpoint for my OSGi service?

I mean, in camel-nmr example  "nmr:ExampleRouter" endpoint is implicitly
created by NMR Component, but i need to link a NMR endpoint with my service,
a simple HelloWorld OSGi service:

<osgi:service interface="com.santalucia.esb.primer.osgi.HolaMundoOSGi" >
		<bean id="holaMundoBean"
class="com.santalucia.esb.primer.osgi.HolaMundoOSGiImpl">
			<property name="mensaje"><value>Hola Mundo OSGi</value></property>
		</bean>
</osgi:service>

I could use 
http://fusesource.com/docs/esb/4.0/fsf_se/ESBFSFSEDeployService.html
EndpointExporter  to expose the bundle as a JBI Service Unit, and use the
JBI endpoint in the orchestration bundle through NMR, but I think there is a
simpler way (without JBI) to do it, it is possible?

I had thought camel log component used the NMR-OSGi linking i was looking
for but I realized it's a native Camel component 

Cheers,

Juan
