I successfully compiled my source using this command:

javac -classpath "..\lwjgl-2.7.1\jar\lwjgl.jar" Game.java

However, when I try to run it using:

java -classpath "..\lwjgl-2.7.1\jar\lwjgl.jar" Game

, it gives me an error:

Error: Could not find or load main class Game

What have I done wrong!? :(

I am certain that there are no syntactical errors and class labeling anomalies.

EDIT: I've also tried running the program using this command, but still nothing. T.T

java -cp "..\lwjgl-2.7.1\jar\lwjgl.jar" -Djava.library.path="..\lwjgl-2.7.1\native\windows" Game

  • it has to be java -classpath "jarpath" <classname>. Commented Aug 11, 2011 at 7:27
  • Sorry, I mistyped the question, but it's revised now. The command I used to run it was java -classpath "..\lwjgl-2.7.1\jar\lwjgl.jar" Game Commented Aug 11, 2011 at 7:39
  • Does your Game class has a main() method? Commented Aug 11, 2011 at 7:41
  • Yes, it does. I even tried a blank source with just the imports, the constructor method and the main method, but still nothing. Commented Aug 11, 2011 at 7:47
  • Does the Game class reside in some package? If so, you've to specify it. Commented Aug 11, 2011 at 8:29

Here is the answer, after endless hours of sitting on my toilet...

java -cp "..\lwjgl-2.7.1\jar\lwjgl.jar"; -Djava.library.path="..\lwjgl-2.7.1\native\windows" Game

Note the semi-colon after the -cp. The SEMI-COLON. That was all that I was lacking. A FRIGGIN' SEMI-COLON.

I hope nobody commits the mistake I did.

Oh, sorry about that. That's the command I used, I just mistyped the question.

Is Game.class inside of that jar file? If not, you probably need to include the path to the class file as well. For the current working directory, try:

 java -classpath "../lwjgl-2.7.1/jar/lwjgl.jar:." Game

(Maybe that : should be a ; on Windows).
