Well, I didn't do anything special to get that service to appear...I am
just using your Main...
The only thing I did was in your FelixHost.callService() where it prints
out the length of the services references array, I added a check for
null so that it doesn't throw an NPE:
Object[] services = m_tracker.getServices();
if (services != null)
System.out.println("sevices length :" + services.length);
else
System.out.println("sevices length :" + services);
After doing this the service does appear, even though I am seeing class
load errors from Spring-OSGi.
Perhaps you are just invoking the method too quickly...I am not sure if
Spring-OSGi uses asynchronous events or not when listening for bundles...

Re: Embedded Felix giving NumberFormatException
Ultimately, I am at a loss to explain what is going on... Perhaps, you could package the minimal set of pieces to reproduce the issue and I can try to look at it locally. Basically, I would need your launcher source with any necessary bundles to install and start.

Which version of Felix and Spring-OSGi are you using? There was an issue where Spring-OSGi was making assumptions about the URL format being returned for bundle resources which was causing it to not correctly discover the Spring resource tiles, which ultimately led to it not creating Spring components/services, etc. Perhaps this is what you are seeing, but I thought it was fixed now. -> richard > > Sameera > > > > On 4/26/07, Sameera Withanage <[EM

You should ensure all the core Spring-OSGi bundles start first.
If you still don't see the spring service then it may be that for some
reason
loading the bundle via the embedded app is not triggering the bundle
event.
You might want to turn on debug logging in log4j.

Re: Embedded Felix giving NumberFormatException
Here's a thought - Spring-OSGi uses a bundle event listener to detect spring
powered bundles (listener is registered by the spring-osgi-extender bundle).
If this bundle is not started when your client bundle starts then it won't get
the STARTED event and so won't wire up the necessary Spring services.
You should ensure all the core Spring-OSGi bundles start first.
If you still don't see the spring service then it may be that for some reason
loading the bundle via the embedded app is not triggering the bundle event.

Re: Embedded Felix giving NumberFormatException
Firstly thank you for all the help.
I checked out the latest code and able to run it without that numberformat
exception. I think I've done something wrong.
But the spring service registration issue is still there. When I launched
Felix from command line I can see the registered services of my sample
spring bundle, but in embedded application it still returns null for

Re: Embedded Felix giving NumberFormatException
I cannot see what is going wrong...it definitely appears to be getting a
different manifest file, because the bundle version number giving you an
exception is ${pom...} rather than a real version.
Perhaps you should let us see your code for launching Felix and
installing the bundle.

Looks like it's using a manifest that hasn't been filtered by maven
and still has the ${pom} variable, which of course is not valid.
The warnings from spring-osgi are possibly related - build issue?
Are you loading this bundle from a jar or directory?
Could you provide a jar / directory listing along with the manifest?
