Hi!

I'm trying to serialize an object and pass it to another via RMI, it works while I'm using the same NFS but when trying to work with external machines I get this error message:

java -Djava.security.policy=file:/users/research/hectorgh/generic/policy
-Djava.rmi.server.codebase=file:/users/research/hectorgh/genserver/client/
generic.Client
Client: Montecarlo instance = rmontec
Client: lookup for genericServer in rmi://electra:1880/genericServer
Client: Connection Established

Trying to get results...Error in processing Montecarlo java.rmi.ServerException:

I'm suspecting that it's a User privileges Error, but I don't know how to fix it, If any Ideas please let me know, thank you.
