(newbie) compiling problem

[Gary]

OK, I decided to try RMI, but I'm getting stuck on compiling. I've
relied so long on Forrte and Eclipse that I can't remember how to
compile.

I have two classes: Foo, and Bar. Bar extends Foo. The point is that I
have one class that needs the other to compile.

I've tried Textpad and the command line, and neither works, although I
have no problem when I do it from Eclipse.

I've put the in the dedfault package and trry this:
javac Foo.java
javac Bar.java

Foo compiles OK, but when I go to compile Bar, I get this message:
---------------------------------
C:\eclipse\workspace\MyTest\Bar.java:2: cannot resolve symbol
symbol : class Foo
location: class Bar
public class Bar extends Foo {}
^
1 error

Tool completed with exit code 1
---------------------------------

I've also triedd putting them in a package together. Nothing works.
I'm sure this is something simple. I know I've done this a million
times, but I can't remember what I did different.

Thanks for the help, and let this be a warning to any of you who think
an IDE is going to solve all your problems.

 

[D Goldman]

you propably don't have foo.class in your classpath.

do something like that in your console:

javac -classpath Path/To/Foo Bar.java

If both Foo and Bar are in the same directory, then you can just do the following:
javac -classpath . Bar.java

Make sure you incluse the ".", since it points to the current directory.

Assuming the following source:

File Foo.java:
package a;

class Foo
{...}
-----
File Bar.java:
package a;

class Bar extends Foo
{...}
-----
Afterwards Bar.java and Foo.java have to be in a subdir named a.
Preferably you should run javac as

javac -da a/Bar

now from the dir below a. This would compile both files (it does it
for me).

Other option: remove the package statements and start the javac from
the same dir the *.java file are in.
