JDBC problem in Java RMI

[Siddhartha]

I am developing a project in Java RMI. I am using (JDBC) Oracle thin drivers and they are in a.zip file called classes.zip. Now when i add a CLASSPATH (setenv CLASSPATH /u/home/sijain/1aman/classes12.zip) in .cshrc to access this file I get wierd problems.
These are the errors its giving to me:-
posImpl.java:7: cannot resolve symbol
symbol : class posIntf

public class posImpl extends java.rmi.server.UnicastRemoteObject implements posIntf

What I feel is ur class is not getting the interface. Did u import the package ? If u can provide the source code of both the interface and the impl class, that could be a help.
