Could someone please tell me how to use the policy tool to set

Hmm. Well the program that gave me the security exception WAS an RMI
program, and one of the exceptions what for not having permissions to
resolv/connect to a host, but I also got a security exception when trying
to open a file.

I'm getting this too. rmiregistry prints it out whenever something calls
Naming.rebind() and any program prints it out when doing Naming.lookup().
I'm using 1.2.2 rc3. Everything does appear to work though (mostly).

All applications can listen on sockets on the localhost for ports 1024

And this is a big security problem? Access specifiers are meant to
protect programmers from doing stupid things, not protect security. Of
course if you hack the jvm you will be able to get access to a private

Uh, yeah, that's right. Sun's jdk says that it doesn't work on smp
kernels. You'll have to use the latest blackdown version. The rc4
version didn't work on smp kernels because the jit it shipped with
couldn't handle native threads, but supposedly the final release has
fixed those bugs. Release

May doesn't mean should. I imagine the spec was so loose because it
could be expected that fine control over the threading might not be
available to the implementors of the jvm on every platform, not because
the writers of the spec didn't think Thread.yield() would be
