rmi and Tomcat 5.5 - Malformed URLException: no protocol: Files

Im running tomcat 5.5 on win64 with jdk1.5.0_07.

I have a problem with a simple RMI server/client test. It works fine if I start the server and client via main methods (I can see my port is listening in netstat).

If I start the server via tomcat it seems like everything is ok, but when I run my client I get the following exception on client side lookup:

java.rmi.UnmarshalException: error unmarshalling return; nested exception is: no protocol: Files
at sun.rmi.registry.RegistryImpl_Stub.lookup(Unknown Source)

... 4 more

Server code:
private static final int serverPort=20000;
private static final String regLookup="RmiExecuteUtilServer";
Registry registry = LocateRegistry.createRegistry(serverPort);

Client code:
registry=LocateRegistry.getRegistry(serverUrl, Integer.valueOf(serverPort));
rmiServer = (RmiExecuteUtilServerInterface)registry.lookup(regLookup);

Funny enough... If I change my server code to:
Registry registry = LocateRegistry.createRegistry(serverPort);

Hashtable env=new Hashtable();

env.put(Context.PROVIDER_URL, "rmi://"+Initialize.getServerIp()+":"+serverPort);
InitialContext c=new InitialContext(env);

I get similar problem when I start the rmi server via tomcat:

Root exception is java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is: no protocol: Files]][

Any suggestions?

If you must post to multiple forums at least let people know so they don't waste time replying to something that was answered elsewhere.

Personally, while it's not OK to cross-post to multiple JavaRanch forums, I think it's OK to cross-post to completely different bulletin boards, like JGuru. It is nice to say you've done so, to save others' time.

Sorry, I haven't done RMI for ages (just CORBA), so can't help with your actual problem.

Betty Rubble? Well, I would go with Betty... but I'd be thinking of Wilma.

Problem solved... I changed the tomcat installation directory so it didn't have any spaces in it. /J
