Finding the potential error via "SEE" through the text is hard work for me :)

Can you just attach your eba here? so that I can quickly have a local try with your eba.

Can you attach your sample here for a check?

I have my SampleApi (interface) exported it.  I don't believe I'm suppose to export the implementation (SampleServer) and web bundle(Sample Web).  But, i just tried exporting them both just to see if it will work and I'm still getting the same error.  I'm somewhat following the CounterApp example.  My web bundle is pretty much the same as the CounterWebBundle (same required import packages and no exports).

Have you exported your application classes in Export-Package of MANIFEST.MF?

Thanks, Ivan.

I added the javax.naming to the import and now getting this error:

I've created a SampleApi(interface), SampleServer(implementation) and SampleWeb(servlet) bundles.  It's using Blueprint.  I ran it in the Apache Aries container and it was fine.  I tried to run it in Geronimo and got
