Hi ,
I would like to send my example to help those who are starting with easybeans. I've used a EZB + EJB on OSGI Equinox . This sample includes a HelloWorld example containing an SLSB and a client for invocation. This example was only possible with EkkeHard Gentz's help.

Hi Missias,
In this example I used easybeans version 1.0.2. Follow the Ekke's blog. You should to use the same versions. Best Regards Fernando 2009/3/23 Missias <josecarlosmissias@...>
