I have classes in this directory structure:
C:\portalbean\portal

All classes in this folder are package as so:

package portal;
class PortalTest implements PortalReadWrite
{
...
}

I have tested the application on the command prompt as so:
C:\portalbean>java portal.PortalTest

This Works.
My problem is that I now want to move the PortalTest.java file to a folder called TestDrivers. This is because I want to have PortalTest2.java ...PortalTestN.java

So thus now PortalTest2.java is in a folder called:
C:\portalbean\portal\TestDrivers

import portal.*; //note this is the only line I have changed
class PortalTest2 implements PortalReadWrite
{
...
}

However the class does not compile. Gives errors such as:

C:\portalbean\portal>cd TestDrivers

C:\portalbean\portal\TestDrivers>javac *.java
PortalTest1.java:1: package portal does not exist
import portal.*;
^
PortalTest1.java:17: cannot resolve symbol
symbol : class PortalReadWrite
location: class PortalFtpTest
class PortalTest1 implements PortalReadWrite

PortalTest1.java:19: cannot resolve symbol
symbol : class PortalFtp
location: class PortalTest1
PortalFtp ftp;
^
PortalTest1.java:25: cannot resolve symbol
symbol : class PortalFtp
location: class PortalTest1
ftp = new PortalFtp();

Please help,
