I do not have a %CLASSPATH% set up. As I understand, this should not be a problem because Javac will assume a classpath of the current directory.

As you can see below, javac is unable to find my Case class even though it's in the same exact directory. Any thoughts on why this is happening? This code works fine when I use Eclipse.

C:Documents and SettingsjoepMy DocumentsGCJsrccodejam2011Round0D>dir /B
Case.class
Case.java
EntryPoint.java

C:Documents and SettingsjoepMy DocumentsGCJsrccodejam2011Round0D>javac EntryPoint.java

Update 1:

After trying to compile from my package root (src), I get a new error (even after deleting the Case.class file)

C:Documents and SettingsjoepMy DocumentsGCJsrc>javac -cp . codejam2011/Round0/D/EntryPoint.java

codejam2011Round0DEntryPoint.java:16: cannot access codejam2011.Round0.D.Case

bad class file: .codejam2011Round0DCase.java
file does not contain class codejam2011.Round0.D.Case
Please remove or make sure it appears in the correct subdirectory of the classpath.
                ArrayList<Case> cases = new ArrayList<Case>();
                          ^

Update 2: It appears to be grabbing the Case.java file from a different package.

C:Documents and SettingsjoepMy DocumentsGCJsrc>javac -d ../classes codejam2011Round0D*.java

.codejam2011Round0DCase.java:4: duplicate class: codejam2011.Round0.C.Case

       ^

bad class file: .codejam2011Round0DCase.java
file does not contain class codejam2011.Round0.D.Case
Please remove or make sure it appears in the correct subdirectory of the classpath.
                ArrayList<Case> cases = new ArrayList<Case>();
                          ^

You need to compile from the package root, not from inside the package.

So, cd to the src folder and compile from there.

javac -cp . codejam2011/Round0/D/EntryPoint.java

Update: as per your new problem, you need to recompile Case.java the same way. It was apparently compiled the same wrong way (from inside the package).
