I Can't reference a class that's in the same package

[Tom Purl]

I have the following two classes. First, I have the Field class.

 
package ff2db.flatfile.data;
public class Field
{
  ...
}

Next, I have the Record class that references the Field class.

 
package ff2db.flatfile.data;
import java.util.HashMap;
class Record
{
  public void addField(Field f)
  {
    ...
  }
}

Both classes are in the same folder, which is /home/tom/Dev/Java/ff2db/flatfile/data. My classpath variable contains the following text:
CLASSPATH=$CLASSPATH:.:$HOME/Dev/Java/Scratch
... so I don't have to use the "-classpath ." switch if I'm compiling a class in the current directory.
When I compile the Field class, I don't have any problems. However, I'm trying the following command to compile the Record class:
[tom@localhost /home/tom/Dev/Java/ff2db/flatfile/data] javac Record.java

 
Record.java:22: cannot resolve symbol
symbol  : class Field  
location: package data
public void addField(Field f)
                                                ^
1 error

Here's what I've tried to fix this problem.

I tried to compile the class from the /home/tom/Dev/Java directory. One newsgroup posting said that this may work. It didn't.

I tried to explicitly reference the Field class by using the folloiwng signature: public void addField(ff2db.flatfile.data.Field f). This also didn't work.

Since both classes are in the same package, I don't know why I'm having this problem. Any help would be greatly appreciated!
Thanks,
Tom

hi Tom,
u have written that you have your classes in,
/home/tom/Dev/Java/ff2db/flatfile/data
folder, but in the CLASSPATH u have
$HOME/Dev/Java/Scratch
i guess that is the problem. don't you have to have $HOME/Dev/Java in the classpath instead?

I also have the "." directory in my classpath. This means that when I compile a program, it adds the current directory to my classpath. So if my java file is in the /foo/bar directory and I use the following command:
[/foo/bar tom@localhost] javac test.java
or in Windows...
C:\foo\bar> javac test.java
...the javac program should add the /foo/bar directory to the classpath.
Thanks for the quick reply Maulin! Does this make the problem clearer? Does anyone else see what could be wrong?
Thanks again!

In case anyone else was trying to figure this out, I think I've finally figured this out.
All I had to do was compile the program from the directory that was the parent of the first element in the package name. So if my package name was tom.test, and my files were in C:\tom\test, I needed to compile my program from C:\. I tried this before on my Linux box but it didn't work. I guess either I forgot something or this behaves differently on Linux.

Hi Tom,
well, it does put current directory but if u've a package structure then it doesn't really work the way u expect it to be....
finally u got urself that what u should do...i ALWAYS use parent dir of the package to compile...
if my package is maulin.apps and i have,
c:\java\test\maulin\apps
then i do cd c:\java\test
then, javac maulin\apps\*.java

now the current dir that is "java\test" is in the classpath where my package resides "maulin.apps" so i don't need to do any explicit settings...
