Does Aries Blueprint require cglib or asm?

When trying to use Aries blueprint (and jpa) from within Pax Exam I get the
following error message:

[RMI TCP Connection(1)-192.168.0.3] ERROR
org.apache.aries.blueprint.container.ServiceRecipe - Error retrieving
service from
ServiceRecipe[name='.component-2']org.osgi.service.blueprint.container.ComponentDefinitionException:
Interceptors have been configured but neither asm nor cglib are available

Does Aries Blueprint require cglib or asm? What version? What bundle do you
recommend?

Thanks Joe,

You're right I use declarative transactions. I tried cglib version 2.1_3_4
and it solved the problem.

Thanks,

Hi Bengt,

Our transaction support uses an interceptor and hence it requires either 
cglib or asm to be available.  From the message below I suspect your 
dependency might be caused by the interceptor required for declarative 
transactions ... but that's just a guess.

In the equinox assemblies that we provide for the Blog and AriesTrader 
samples we use asm version 3.2 (we specifically use asm-all-3.2.jar).  I 
think we use cglib version 2.1_3_4 in other places.  I suspect either of 
those should work.

Hi Bengt,

Blueprint does not require asm or cglib for standard functionality. But some of the extra stuff in particular interceptors need the ability to proxy classes rather than interfaces. In such a case either asm or cglib is required. Also, I believe if you want to export classes rather than interfaces to the service registry.

The versions we use (in the itests) are either (from blueprint/pom.xml):

<dependency>
    <groupId>org.apache.servicemix.bundles</groupId>
    <artifactId>org.apache.servicemix.bundles.cglib</artifactId>
    <version>2.1_3_4</version>
</dependency>

or

<dependency>
    <groupId>asm</groupId>
    <artifactId>asm-all</artifactId>
    <version>3.2</version>
</dependency>

I imagine you need interceptors for declarative blueprint transactions, correct?

Regards,

Valentin
