Java command not working in console

I am completely new to programming and use a public computer. I've been running java console programs without issue but recently when I pull up the console window it won't run the java command against the class file. Compiling and creating the class file works fine however. The message returned says "File not opened". Is this a DOS window parameter that got changed somewhere or a java setting? typical input would be something like below for me....

console window

set path=C:\Program Files\Java\jdc1.6.0_11\bin


java SampleClass
"File Not Opened"

Thanks for help!

Welcome to JavaRanch.

Does it literally say "File not opened"? What is the exact error message? Did the file compile successfully (without errors)? Do you have a file SampleClass.class in the directory where you're running the command?
