I have created below bat file to run my RMI server

@echo Off

set classpath=C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\RMI_Server\bin\;
set classpath=C:\policy.all;
set classpath=C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\RMI_Server\log4j-1.2.12.jar;
set classpath=C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\RMI_Server\log4j-1.2.15.jar;

set classpath=%classpath%;.

I am able to run my RMI server but when RMI tries to connect to RMI server I get following exception

Execption in RMI...java.rmi.UnmarshalException: error unmarshalling return; nest
ed exception is:
        java.lang.ClassNotFoundException: ExecutorInterface (no security manager

I have give policy file and code base while running.I am not getting what I am missing here. How to add lcass in rmiregistry's path?

Solution
    1. Setting the CLASSPATH to 10 consecutive values doesn't work. It only takes the last value. You need to set it =%classpath%;. You also need to quote all those directories with spaces in their names.
    2. Putting policy.all on the CLASSPATH is pointless.
    3. java.lang.ClassNotFoundException: ExecutorInterface says exactly what is wrong. That class is not present at the client.
