Java classpath, class not found

Question

I'm trying to be able to do homework on my work computer for a Java class. I see an old jdk is installed and I created a .bat to have my environment variables set up. I can do a simple "HelloWord" example, but now when I try to do a simple example where I create a FileOutputStream object, I get class not found on my FileOutputStream. Is this because my classpath is not set up, or because it can't find the io Package? Thanks.

Edit:

Here is my work directory structure:
C:\dmd\jdk1.3.1
within jdk1.3.1 ->
bin
jre
lib
src (my files)

in my bin folder, i have this .bat file:
@echo off
SET TOOLS_HOME=c:\DMD
SET JAVA_HOME=%TOOLS_HOME%\jdk1.3.1
SET PATH=%JAVA_HOME%\BIN;%PATH%
SET CLASSPATH=.;

Give us a chance! Show us your .bat and/or your Java code. We're not telepaths! — Carl Smotricz

mumble, java.io.FileOutputStream is part of java language since 1.0. I do not think that your jdk is older than that. — andcoz

PATH looks good, JAVA_HOME is irrelevant, that means it's probably in the coding, as Tom Tresansky hints. — Carl Smotricz

Do you have an import java.io statement in your source file using the FileOutputStream?

Or import java.io.FileOutputStream. I thought mentioning you need to import from java.io might be a more general way of saying that both are acceptable.

Yes, the import java.io.* is there.

Both - it cant find the IO package because your classpath isnt set up correctly. Do you have JAVA_HOME set correctly?

We don't know just how old this Java installation is, but since version 1.3 Java doesn't need or respect JAVA_HOME any more.
