I see two potential problems.
1. Did you mean to type colons? I suspect you need a space between -ea and propjsp and a period between propjsp and SpellCheck. (I'm not familiar with -ea, so I don't know what affect it may have.)
2. Where is your command prompt when you try to run it? If your source code files are in "C:\Kevin\Java Projects\", then the compiled files should end up in "C:\Kevin\Java Projects\projsp", but you will need to run the command prompt while in "C:\Kevin\Java Projects\".
Try java -ea propjsp.SpellCheck from "C:\Kevin\Java Projects\"
