Hi,
I wrote a class file ComeAgain.java with Emacs in Cygwin:
public class ComeAgain
{ private static int n;
public static void main(String[] args)
{ n = 57;
System.out.printf("Come in number %d please%n", n);
}
}
I compiled the script successfully with "javac ComeAgain.java" in
Cygwin. But when I try to invoke with "java ComeAgain", I got an error
message:
Exception in thread "main" java.lang.NoClassDefFoundError
Do you have any idea why?
Try
java -cp . ComeAgain
If that works, then you have a problem with your CLASSPATH environment
variable setting---it needs to include the current directory "."
If that doesn't work, then you may have saved your *.java file in the
wrong case. mv it to a different name and then mv it back with the
proper capitalization, then recompile and rerun.
HTH,
