in fact, physicalrep.jar (containing WSIFDynamicProvider_Physicalrep ) and
wsif.jar (containing WSIFServiceImpl) are in the same directory!!! It's the
common lib directory of Websphere. That's why I'm confused. I don't
understant why it doesn't work. Furthermore, WSIFPluggableProviders and
WSIFServiceImpl are in the same package.
