The no classes error is normal, there actually is nothing to run.
If you add some statement :
import system.CharColor
say "Hello world"
Then the compiler announces :
error: File jcurses.jar(system/CharColor.class) does not contain type system.CharColor as expected, but type
jcurses.system.CharColor. Please remove the file, or make sure it appears in the correct subdirectory of the class path.
/home/xx/src/nrj/jc.java:1: Class system.CharColor not found in import.
/* Generated from 'jc.nrx' 25 Sep 2013 12:13:06 [v3.00] *//* Options: Crossref Decimal Java Logo Trace2 Verbose3
*/import system.CharColor;
^
2 errors
Compilation of 'jc.nrx' failed [javac failed]
Thus, you need to jar the class files from the jcurses directory (jar cvf jcurses/*/*class)
and code
import jcurses.system.CharColor
say "Hello world"
All this, because the original java file has the following package statement:
package jcurses.system;
..
public class CharColor {
You have to respect directory structure, even in the jar.
