Jonahthan, Thanks for the tip! I just figured out that firewall provented accessing port 4160 and 8081 on the master machine. After getting registrar object back, however it has lookup problem now. see the attached exceptions. The jini services(includeing JavaSpace) are on host "s04", but worker machine(s03) tries to lookup javaspace object at localhost instead of from s04. Here is my /etc/hosts file:
192.168.0.4 s04.meng.com s04 127.0.0.1 localhost 192.168.0.3 s03 what did I miss? Thanks a lot, Andrew INE: main: name = "com.sun.jini.reggie.RegistrarProxy", codebase = "http://s04.meng.com:8081/reggie-dl.jar http://s04.meng.com:8081/jsk-dl.jar";, defaultLoader =
