Ok, no problem.

The Appia framework (http://appia.di.fc.ul.pt) is 100% java and the
next release will be fully compliant with this interface: http://
jgcs.sf.net, which (for end applications) is more simple than the
current Appia interface.

I would like to implement Shoal using Appia and possibly contribute
with the code, if it is welcome. Can you give me some guidelines (or
links) for me to start? I just have to implement the SPI (classes of
the package com.sun.enterprise.ee.cms.spi)? If it is only these
classes, after the implementation how Shoal does to distinguish
different implementations? Can the same Shoal application choose Jxta
or Appia implementations by being configured to use one or another?

Thanks and king regards,
