Hi there. I've just installed Jonas 2.1.1 on a Windows NT machine with Sun JDK 1.3 and J2SDKEE 1.2.1. The examples compile fine, but when I try to run EJBServer.bat, I get the error output below. I've taken a quick look at the jonas.common.RemoteObject source and there doesn't seem to be anything strange going on there -- is this a Sun bug? Has anyone else run into it? (And, P.S., does anyone know of an easy way to turn the JONAS source into "clean" Java source without all the #ifdefs and things?) d:\java\local\jonas-2-1-1\examples\src\eb>java -Dinstall.root=d:\java\local\jona s-2-1-1 -Djava.security.policy=d:\java\local\jonas-2-1-1/java.policy org.object web.jonas.server.Server JOnAS Server, version 2.1.1, running on rmi.
