RMI and Java1.2

[Juan C. Estrada]

I'm trying a simple RMI example on Java1.2 which was origianlly written
for Java1.1 It's a basic remote method call to a "hello" method that
prints out "Hello World". Anyway, I keep on getting this error stack
trace. Anyone have any idea if there's a difference in the RMI package
between 1.2 and 1.1? btw, it works with Java1.1

mystation 10> java -Djava.rmi.server.codebase=file://home/rmi/hello/
hello.HelloImpl

HelloImpl error: access denied (java.net.SocketPermission sun.moon.com
resolve)

I would be happy to provide the code if needed. Thanks in advance for
any help!

Hello Juan,

You need to implement a java security policy on the command line for jdk1.2.
See the following url for an explaination:

Good luck.
