Re: Embedded Felix giving NumberFormatException

2007-04-27 Thread Sameera Withanage 

Hi,

The services are the exact ones I get when I install the bundle to
standalone Felix. But in embedded version there are no services for this
bundle.

Still no success even with you suggestions.

Thank you

If so, I am seeing that:

- services 32

Simple-Service-Sample (32) provides:

Bundle-SymbolicName = org.springframework.osgi.samples.simpleservice
Bundle-Version = 1.0
objectClass = org.springframework.osgi.samples.simpleservice.MyService
org.springframework.osgi.beanname = simpleService

So, I am not really sure if I am on the right track, since I don't use
Spring-OSGi at all.

 Below you appear to read Felix' configuration properties from the
 roland.properties, which sets the org.osgi.framework.system.packages
 property inside of it, including all of the packages exported from
 the underlying JRE. Your code below then overwrites this value and
 sets it to only export the core OSGi packages along with your
 simpleservice package.

 The end result is that no JRE packages are being exported any more
 after you overwrite the value. To remedy this situation, you should
 either:

   1. Add your simpleservice package to org.osgi.system.packages
  property in roland.properties or
   2. Append your simpleservice package to the existing value in the
  code below.

 I am not sure if this will solve anything, but I am still working to
 get your example to compile since the pom files included with it are
 not working for me.

 One other minor thing I noticed below, you have an extraneous ';'
 character when you add your simpleservice package.  I think Felix
 would ignore this, but you should probably still remove it. The ';'
 is used to separate packages that share attributes or to separate the
 attributes themselves.

 I will keep trying to build your code. Let me know if any of the
 above makes a difference or if you discover the issue in the meantime.

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...

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

services[].

Re: Embedded Felix giving NumberFormatException

2007-04-26 Thread Stuart McCulloch 

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.
You might want to turn on debug logging in log4j.

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.

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.

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.


Send it to me off list.

2007-04-26 Thread Richard S. Hall 
Well, I sort of take back what I said below...since you are not 
launching with the standard launcher, property substitution does not 
happen in the roland.properties file, so you have to overwrite that 
value with a real value.


I will keep playing with it...

Richard S. Hall wrote:

Below you appear to read Felix' configuration properties from the 
roland.properties, which sets the org.osgi.framework.system.packages 
property inside of it, including all of the packages exported from the 
underlying JRE. Your code below then overwrites this value and sets it 
to only export the core OSGi packages along with your simpleservice 
package.


The end result is that no JRE packages are being exported any more 
after you overwrite the value. To remedy this situation, you should 
either:


  1. Add your simpleservice package to org.osgi.system.packages
 property in roland.properties or
  2. Append your simpleservice package to the existing value in the
 code below.

I am not sure if this will solve anything, but I am still working to 
get your example to compile since the pom files included with it are 
not working for me.


One other minor thing I noticed below, you have an extraneous ';' 
character when you add your simpleservice package.  I think Felix 
would ignore this, but you should probably still remove it. The ';' is 
used to separate packages that share attributes or to separate the 
attributes themselves.


I will keep trying to build your code. Let me know if any of the above 
makes a difference or if you discover the issue in the meantime.

2007-04-26 Thread Richard S. Hall 

After yet even more poking around, I am not sure what is going on...

I am definitely seeing some errors from Spring...looks like some class 
loading issues...I am not sure.


However, am I supposed to be seeing bundle 32 offering a service?

If so, I am seeing that:

- services 32

Simple-Service-Sample (32) provides:

Bundle-SymbolicName = org.springframework.osgi.samples.simpleservice
Bundle-Version = 1.0
objectClass = org.springframework.osgi.samples.simpleservice.MyService
org.springframework.osgi.beanname = simpleService
service.id = 26

objectClass = org.springframework.context.ApplicationContext
org.springframework.context.service.name = 
org.springframework.osgi.samples.simpleservice

service.id = 27
-

So, I am not really sure if I am on the right track, since I don't use 
Spring-OSGi at all.

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?

Re: Embedded Felix

Hi Asaf,

The main problem you would probably face when getting your hands on
something inside the OSGi framework is ClassLoading issues: You will have to
use a class (usually and interface) which is loaded from a class laoder
commoner to both the OSGi framework and the outer world.

On the other hand, you might want your inside objects make themselves known
to the outside world through - for example - a bridge service, which is
registered by a BundleActivator given to the Felix constructor. This is how
the Equinox HttpService to Servlet bridge works.

The details - as always - depend on what exactly you want to achieve.

Anyway, I would not hold on to the BundleContext given to an Activator for
this.

Hope this helps a bit.

Felix

Yes, by listing such packages in the org.osgi.framework.system.packages
property given to the Felix constructor, you may make external packages
visible inside the framework and hence use and share objects created from
those classes.

To be precise, you don't pass in BundleActivator instances to the Felix 
constructor, but to Felix.start().


Regardless, this is the appropriate way to embed Felix and get access to 
the System Bundle context object, because each passed in BundleActivator 
instance is treated as an extension of the System Bundle, where start() 
and stop() on each will be invoked when the System Bundle is started and 
stopped, respectively.


This is the approach for your host application (i.e., the embedding 
application) to get a context to interact with the framework and any 
installed bundles/services, such as installing/removing bundles or 
using/providing services.


All is not roses however, there is a catch. If the host application 
wants to use services from bundles or provide services to bundles, the 
service interface classes must come from the class path so that the host 
application and the bundles use the same class definitions. As Felix 
points out elsewhere, you can use the org.osgi.framework.system.packages 
property to export packages from the class path via the System Bundle.


There is one alternative, which is if you just want to use services in 
the host application, you can instead use reflection to invoke service 
methods, then the host application does not need access to the class 
definitions at all.
