rMI ran once and then crashed

I wrote asmiple rMI client /server each accessing one method on each side. I ran it last night.Tonigh without touching the programs I compiled them again using javac...and they are not compiling. It doesnt recognise the interface.strange.

I should add that the client is in a diff package and server in a diff package.and in the server side I import the client package and that is the first error I get on the server compliation that the client package does not exist.

You must specify codebase parameter in both server and client instances. To do that, just use -Djava.rmi.codebase=<codebase directory>.
