Problems running a simple RMI

Question

Hi there,
I have had alot of problems running a small RMI program.
It has now boiled down to a java.lang.NoClassDefFoundError
when i try to use my policy file.
The program complies, when i run javac *.java
It also creates the stub, when i run rmic.
I have trawled alot of forums and the closest answer i got was "add your classpath".
As im a student of java, this does not really tell me much.
The class/java files are in
C:\Documents and Settings\MONDARIZ\workspace\RmiHello\server
The policy file is also in the folder.
I must add, that the program is from an example, so i would not think there is any coding errors.
Also when i run it en eclipse, i get "Hello server failed: java.security.AccessControlException: access denied (java.net.SocketPermission 127.0.0.1:1099 connect,resolve)"
So it seems something is running.

The answer you found is correct. Java needs to know where to find the class files for execution.
For starters, use the environment variable CLASSPATH. Set the value to:
C:\Documents and Settings\MONDARIZ\workspace\RmiHello\server
This way whatever you run (RMI Registry, Server, Client) has the proper class path. When you get everything running ok, then you can look into other methods of specifying where the class files are found.
Eclipse, as well as command line Java starts, need to find the policy file. Set up this:
-Djava.security.policy=C:\Documents and Settings\MONDARIZ\workspace\RmiHello\server\your_policy_file.xxx
