Re: Re: Re: Strange ClassCastException when looking up SLSB RemoteHome from "external" .war webapp

unzippped the nightly build,
created a new jonas_base,
set local.registry to FALSE,
set security.manager to TRUE,
deployed my datasources and the ear and the axis2-war

---> now the exceptions are gone, works for me now. thank you guillaume!


regards,
HANS
