Exception in thread "main" java.lang.NoClassDefFoundError

[baltimore]

Hi, for my class lab assignment I had to copy files from one directory and put them in my /Java/Lab4/inventory/ directory, I can compile my Inventory.java file by typing

javac -classpath $HOME/Java/Lab4 Inventory.java

that then creates Inventory.class file in that same directory... and i want to run it; that's where the problem is; to run it I'm typing

java -classpath $HOME/Java/Lab4 Inventory.class

I've also tried
java Inventory.class

The error I'm getting is

Exception in thread "main" java.lang.NoClassDefFoundError: /users/klepeis/Java/Lab4

Thanks.

When running the class don't include the .class like so

java -classpath $HOME/Java/Lab4 Inventory
