Compiling interfaces

Question

Hi,
I have an interface Compute.java
package compute;
import java.rmi.Remote;
import java.rmi.RemoteException;
public interface Compute extends Remote {
Object executeTask(Task t) throws RemoteException;
Also there is one more interface in the same package "Task.java".
package compute;
import java.io.Serializable;
public interface Task extends Serializable {
Object execute();
Now these two files are placed in compute directory whose path is
C:\sharvan\src\compute
I tried compiling Compute.java interface using the follwing command
C:\Myjava\mine\sharvan\src> javac compute/Compute.java
But ended up getting the following error
compute/Compute.java:7: cannot resolve symbol
symbol : class Task
location : interface compute.Compute
Object executeTask(Task t) throws RemoteException;
I downloaded these interface files from RMI trail in the Java tutorial.
Any idea how to rectify this error.
Thanks,
sharvan

sharvan,
MAHIM_MISHRA's comments are incorrect. The order in which you compile the classes is irrelevant when using javac.
The problem is that your src directory is not on your compile-time classpath or sourcepath. The fact that Task.java is in the same directory as Compute.java is irrelevant if that directory cannot be found by searching the classpath.
For now, use the following command line to compile:
C:\Myjava\mine\sharvan\src> javac -classpath . compute/Compute.java
Then look up classpath and sourcepath in your Java books and online. Search these forums and you'll find plenty of old threads about it.
