I have a little calculator applet that uses RMI calls to a compute
server engine. What is driving me nuts is the RMI stubs don't always
seem to work. Sometimes they do, the next compile (with no change
to the source) they don't.
Here is some relevant output:
local:~> rmiregistry&
[1] 6623
local:~> cd myjava
local:~/myjava> javac engine/ComputeEngine.java
local:~/myjava> rmic engine.ComputeEngine
local:~/myjava> comp
ComputeEngine exception: RemoteException occurred in server thread;
nested exception is: java.rmi.UnmarshalException: error unmarshalling arguments;
nested exception is: java.lang.ClassNotFoundException: engine.ComputeEngine_Stub

Engine ready.
^C
local:~/myjava> alias comp
comp='java -Djava.security.policy=java.policy
-Djava.rmi.server.cobebase=. engine.ComputeEngine'
local:~/myjava> cat java.policy
grant {
permission java.security.AllPermission;
};
local:~/myjava>
Sorry for the long lines.
As I said before, this is totally inconsistent, as far as I can tell. I
haven't changed the source at all, and I usually run in the same
directory all the time. Any ideas?
