Execute Java Classes from command line

Hi everybody,
I created a project with 2 packages , and no external libraries required , that works well on eclipse.
But when I try to run it from command line java give me strange errors : (note that java is correctly set to the path).

My project is located at C:\thesis\thesis\classes
then I have 2 packages "app" and "agentLibrary".
I have simply to exectute the Main class in "app" (which cointains reference to some "agentLibrary" classes).(The main class has a void main method with no parameters).
I tried this : C:> java -classpath C:\thesis\thesis\classes\ app.Main
but I get errors...Exception in thread "main" java.lang.NoClassDefFoundError app/Main
How do I solve this problem?

Does the file C:\thesis\thesis\classes\app\Main.class exist?

java -classpath C:\thesis\thesis\classes\ app.Main

Remove the backslash at the end of the classpath (after "classes").
