netbeans IDE 5.5 RUN（RUN出）
RUN出，是什程序
的程序程序：
public class NewClass {

/** Creates a new instance of NewClass */
public NewClass() {
}
public static void main(String args[]){
System.out.println( "asdasdasdasd ");
}
}
RUN出:
ERROR - Ant is misconfigured and cannot be run.

我以前用bate版本,也有这样的问题.
换了版本就OK了!
