Hi Gunnar,

Thx for the suggestion.

BTW ( maybe it was not clear as i've not specify it in my previous messages ):

1) i'm not using  javax.activation and mail packages  *only for sending/receive mail* but in general to handle
 *attachments in general..

2) this would work if you've the total control on your client code... but if for example you're usinf
third pard libraries it would not.

Looking around in the net the problem is in the implementation details of activation and mail packages.

The solution of keeping activation and mail together was a suggestion that has been confirmed
on osgi-dev mailing list too... so would make sense for me.

The only solution i've found is to merge activation and mail packages in 
the same bundle and make this bundle exporting a specific
version of the two packages and then adjust all my client bundles to 
import this version.
    

I'm using a different approach. Basically, javax.activation allows to
set a custom CommandMap. This allows to inject an OSGi-aware CommandMap.

private void doSend(final Email email) throws EmailException {
  final ClassLoader tccl = Thread.currentThread().getContextClassLoader();
  try {
    // make sure to use *our* bundle class loader

Thread.currentThread().setContextClassLoader(getClass().getClassLoader());
    CommandMap.setDefaultCommandMap(getMyCommandMap());
    email.send();
  } finally {
    CommandMap.setDefaultCommandMap(null);
    Thread.currentThread().setContextClassLoader(tccl);
  }
}


Then I re-used the CommandMap implementation from Geronimo
(org.apache.geronimo.javax.activation.GeronimoMailcapCommandMap).
